Review - Gens Ace 2S 5000mAh HardCase 100C LiPo Battery

Remember Gens Ace batteries? Yes, that is the same company that won not one, but two, of our LiPo battery shootouts back in the day. Now days, they are cranking out batteries of all shapes and sizes to help keep your truck running as fast as it can.
It has been a while since we tested a Gens Ace pack, so we grabbed one of their 2S 5000 LiPo Batteries to put it through the gauntlet. Does it have plenty of power? What about runtime? Can it take a standard basher style beating? Read on to find out…
From: Gens Ace
Direct Link: RS 2S1P 5000 100C LiPo

Quick Specs:
  • Capacity – 5000mAh
  • Voltage – 7.4
  • Discharge Rate – 100C
  • Max Burst Discharge Rate – 200C
  • Cell Configuration – 2S1P
  • Net Weight – 305
  • Length – 139mm
  • Width – 47mm
  • Height – 25.1mm
  • Connector Type – 4.0mm bullet to Deans
  • Wire Gauge – 12
  • Balance Connector Type – JST-XHR
  
 
 
Set-Up Notes: We used the Gens Ace in a variety of vehicles to check out its power. The trucks used included an RC4WD Marlin Crawlers Edition TF2 RTR, a Pro-Line PRO-MT 4×4, and a Losi SCTE.
Fit: The Gens Ace uses a standard sized case. This allows it to be used in a plethora of different bash oriented vehicles. As far as fit goes, we didn’t have an issue with the pack’s form factor. It fit excellent in all three of the trucks that we used it in. Because the Gens Ace uses bullet connectors at the case, that can cause issues in some tighter installs where height is limited (because of how the bullets stand up), otherwise, if your truck has a standard sized battery tray, you shouldn’t have any issues.
Power: Ya, this is what most people care about when looking at a battery pack. The Gens Ace we got for testing was a “normal” LiPo, meaning it was not a LiHV design. Its maximum voltage is set at 8.4 volts, just like every standard LiPo.
The heaviest load that we put on the Gens Ace was when using it in our Pro-Line PRO-MT 4×4. The Pro-Line is a 4wd monster truck, which means it sports a whole lot more rotating mass than something like a 2wd buggy or touring car. When using the Gens Ace in our Pro-Line truck we noticed that we had some Serious power on tap. From a dead stop the Gens Ace provided some pretty spectacular torque (can you say wheelie monster?) and it kept on pulling like a beast until the motor ran out of gearing. Later we went on to use the pack in our SCTE and TF2. The Trail Finder 2 draws very little current, but we appreciated the pack’s solid power and runtime. In our SCTE, the Gens Ace also did a fantastic job of trying to blow all four tires off the rims.
We were not able to compare the Gens Ace directly with a brand new pack from another company. However, from memory we could just tell that the Gens Ace was certainly at no loss for yank.
Runtime: We measured capacity on our test pack at 5088mAh (on a 1C charge/discharge), which is a good thing. Too much over, or under, either means poor quality control or marketing shenanigans, thankfully the Gens was fairly close to spot on.
While driving, we received good runtimes with the pack. We saw around 18 minutes on our Castle powered SCTE, which is right where it should be compared to other packs we’ve driven it with.
Durability: Yes, we put the Gens Ace through our normal testing. It withstood several roof jumps, multiple hard slams, plus plenty of water action when we used it in our TF2. At the end of the review, the Gens Ace was still working fine, we experienced no issues of any type. Also, we are nearing 50 cycles on our test pack and it still puts out plenty of voltage while under a load, just like a good pack should.
Final Verdict: From our testing, it looks like Gens Ace has not lost a step from the days when they were winning our LiPo battery shootouts. We found the 100C Gens Ace 2S 5000 to be a solid battery pack. It put out great power, it had solid runtime, and it put up with our abuse without venting internally or dying. If you are in the market for a great quality, yet affordable, 2S LiPo, we think it is well worth your time to try out the Gens Ace.

What is in car emergency kit

As anyone who has ever broken down on the interstate, or even worse, on a rural back-road. There are few situations remotely as helpless and frustrating. Virtually all vehicles come with a basic car jack and spare tire, however, there are countless situations where these necessities are exceedingly useless.
There are plenty of tried-and-true tools to have at your disposal when you break down, and even a few lesser-known gadgets and tricks. With these helpful utilities, you’ll be able to stay cool under pressure, even if you are a little overheated under the hood. Here are xxxx essentials to pack in your car's emergency kit.

#1 Reflectors

One of the most dangerous aspects of being stuck on the side of the highway is the risk of collision with passing vehicles. Placing reflectors at successive distances behind your vehicle will help warn other drivers and create a buffer between your vehicle and oncoming traffic.

#2 First aid kit

If you're involved in a minor collision, having a first aid kit at your disposal is crucial. Be it a car accident or a misstep on the trail-head, gauze, bandages, antiseptics, and pain relievers are all handy items to have around during an accident.

#3 Power bank with a flashlight

The power bank with a flashlight is one of the most important items in any emergency kit. Whether you're changing a tire roadside or simply trying to flag down help, a little light can go a long way in an emergency. Power bank give your cellphone more juice power. Tattu 10400mAh power bank is good choice.

#4 Fire extinguisher

When dealing with combustibles such as gasoline, it's probably a good idea to have a fire extinguisher handy. After a car crash, a small fire can escalate into a much bigger problem in no time.

#5 Ponchos

Breaking down is bad enough, but having to change a tire roadside in the rain is even more frustrating. While a basic poncho probably won't save your life during an emergency, it will certainly make your life easier if you need to walk a small stretch in the rain to find help.

#6 Stinger USB Emergency Tool

The Stinger USB Emergency Tool is certainly something to have at your disposal when things go awry. After a major accident, car doors and seat belts may be jammed. The Stinger packs a powerful punch to shatter the dashboard or nearest window allowing you to quickly exit the vehicle. The backside of the device incorporates a blade to cut through a malfunctioning seat belt as well.

#7 A Car Jump Starter

When you car battery bad, you can use jump starter to starter your car. Also most of jump starter include jumper cables, that are so great if there are other car nearby to give you a friendly jolt. The Tattu Car Jump Starter is one of the most reliable options on the market.

Anything else?

What is difference between X-Frame and H-Frame?

FPV quadcopter racing becomes more and more popular, most of pilots like to diy FPV drones, but many beginners are hesitant what they choose the FPV frame: H frame or X frame? What is difference between X frame and H frame?

H-Frame

H-frames as the name suggest form extended arms from the body that form a shape of the letter H. The H-frame drones were the first drones and have continued to become popular to many over the years. They boast of very strong but heavy frames, they are capable of carrying maximum lots of FPV gear and running a LiPo battery. They have a relatively wider base guaranteeing them stable rolls.
I would confidently say they are good if you are a starting FPV race due to the capability and durability factors especially the batteries of H-frame drone tend to last longer since their positioning ensures they are not easily damaged.
It also makes a suitable best drone frame for racing as it offers plenty of room for easy build and modifications.

X-Frame

X-frames stand out as the big names in racing and freestyle. Configured in an X shape that characterizes its arms it guarantees stability from the centralized center of gravity.
They comfortably perform stunts, rolls and flips. They are also characterized by a symmetrical pitch and roll axis.
Their battery is however more vulnerable in case of a crush due to its location at the base of the done.
X-frames are the best FPV racing frames due to flexibility and predictability in their handling.
H-frames may stand out for beginners in FPV racing but X-frames are rated the best drone frame for racing.
Other popular frames include the v-tail, hybrid X and stretched X frames that are modified for different capabilities and performances. A disadvantage of the unpopular racing drones is that they require custom motors and some parts. That could be a real hustle when you require replacements and spares.
The different frame you need to choose the different battery. For H frame, you'd better to choose long size batteries, such as Tattu 450mAh 2S or 3S or 4S 75C lipo batteries, they all fit H frame perfectly. For X frame, I recommend Tattu 1300mAh or 1550mAh 4s 95c square lipo batteries.

Which battery for Mini FPV Drone: 2S or 3S?

Last week I received from Gens Ace two Li-Po batteries for review. The Tattu 2s 800 mAh and Tattu 3s 450 mAh. Firstly, I thought about making an individually test of each battery, but latter I found it more helpful to make a side by side comparison of them.
Both Li-Po batteries are suitable for micro class FPV drones like the Blade Torrent 110 and KingKong ET series. Weighing about the same (~42 grams), I'm curious to find out which one will perform better (top speed vs flight time).
For my tests I will use the KingKong ET125 drone, which weights about 120 grams and it is equipped with 4-in-1, 10 Amps ESC (2-3s rated) and?7500 KV brush-less motors. Roughly, the number before "KV"; represents RPM/Volt (under no load!), so higher battery voltage means more RPM, respectively higher speed.

Which battery is best for micro racing drones, 2s or 3s one?

Disclosure: I received these two LIPOs as part of a product review collaboration with Gens Tattu. Although the batteries were offered for free, all opinions in this article remain my own and I was in no way influenced by the partner.
Both batteries came well packaged and, as I requested, with JST discharge plug. While both LIPOs weights about 42 grams, they have a bit different form factor. As usual for Tattu batteries, they came half charged, about 3.82 V/cell.

Tattu 2s 800 mAh LiPo specs

  • Number of cells: 2 (2s);
  • Voltage: 7.4 V (3.7/cell);
  • Capacity: 800 mAh;
  • Max Continuous Discharge: 45C (36A);
  • Discharge Plug (drone side): JST-SYP-2P;
  • Max Burst Discharge: 90C (72A);
  • Dimensions: 51.6 x 25.6 x 21 mm;
  • Weight: 42 grams.
As the stock battery of the KingKong ET125 has only 550mAh, I'm expecting at least 1 minute bonus of flight time for the extra 250mAh. Weight difference between 550mAh and 800mAh is about 7 grams only.

Tattu 3s 450 mAh LiPo specs

  • Number of cells: 3 (3s);
  • Voltage: 11.1 V (3.7/cell);
  • Capacity: 450 mAh;
  • Max Continuous Discharge: 45C (20.25A);
  • Discharge Plug (drone side): JST-SYP-2P;
  • Max Burst Discharge: 90C (40.5A);
  • Dimensions: 54 x 29 x 13 mm;
  • Weight: 41 grams.

Tattu 2s 800 mAh vs Tattu 3s 450 mAh

First off all, powering your drone with higher voltage batteries (like 3s instead of 2s) can produce permanent failure of electric parts. My suggestion is to check the "s" ratting of each individual component. For example, the motors and ESCs could be rated for 3s, but the VTX only for 2s.

After five charging/discharging cycles, I fully charged the batteries at 1 Amp. As you can see in the comparison table bellow, both LIPOs ended well balanced.

Real world test

Next day, with confidence I went out to do some real world test. Firstly, I loaded the 2s LiPo into the KingKong ET125. As you can see in the video bellow, due the strong wind gusts, my flight was pretty erratic, so the results are not too relevant. I need to repeat it in more calm day.
https://www.youtube.com/watch?v=WRLrwzKxodM

Although, KingKong clearly says that is risky to use 3S LiPo batteries with the ET125, it worked very well. I noticed some improvements, but you need to be a damn good pilot to take advantage of the extra speed provided by the Tattu 3S 450 mAh. IMHO, 7500 KV motors are just fine with 2s batteries, especially with a light weight frame.
Tattu's "Less is more" aka "Less weight, more flight time" slogan, proved to be pretty fair. While their 2s 800mAh LiPo has ~19.05 mAh/gram storing capacity, the 550 mAh Gaoneng LiPo has only ~15.71 mAh/gram. Compared to stock battery I got more than 1 minute extra flight time.

Final words

Whether you are looking for extra power for outdoor racing and freestyle or extended flight time for indoor practice Gens Ace Tattu has the proper battery for your micro FPV drone (Blade Torrent 110 / KingKong ET125). You can find the 2s 800 mAh for $9.99 and the 3s 450 mAh for $9.89. Free shipping to US is available for orders over $49.

Tattu 1800mah 4S 75C Battery review: long flight time for FPV drones

Today we’re going to find out how long it takes to charge the Tattu 4s 1800mah 75c and what the real world flight time is, in comparison to 1300 mAh batteries which are more common for racing drones.

When it comes to racing quadcopters, flight time is not as important as it is in the case of cruising drones. More important is the take-off weight and you need to keep it as low as possible. More weight means less agility and lower speed.

By comparison, the Tattu 4s 1800mah 75c has 193 grams and the Tattu R-Line 4s 1300mAh has only 165 grams. I’m very curious to find out if the extra capacity (500 mAh) will counteract the increased weight.

Review of the Tattu 4s 1800 mAh 75C Li-Po battery

Although I received the Li-Po about a month ago, only now I had the time and mood to review it. You know, battery testing/review is pretty time consuming.
Battery comes well packed with charging plug protector and safety instruction. At first look it seems very well made with good quality terminals.

Battery pack measures around 90 x 33 x 30 mm (L, W, H). Due to the aluminium envelope, the Tattu 1800 mAh weights a bit more than other 4s Li-Po batteries with same capacity. After a bit of research I found out that this producing technique provides not just better heat dissipation and impact resistance, but also compression, in order to minimize puffing during high discharge.

Tattu 4s 1800 mAh 75C battery technical specs

- Suitable for FPV racing drones;
- Minimum of 1800 mAh storage capacity;
- 4 cells of 3.7v. Total voltage of 14.8V;
- Total power of ~ 26.64 Wh;
- Up to 5C charging rate (do not exceed this value!);
- High discharge rate (75C);
- Max Cont Current of 135 A;
- Maximum burst discharge rate of 150C;
- Max Burst Current of 270 A;
- JST-XH charging plug;
- XT60 discharge (drone) plug;
- Net Weight: 198 grams;
- Dimensions: 90.30 x 33.27 x 29.90 mm (L W H).
Battery came about half charged (48%), which is recommended for storing. I measured 15.34V on the XT60 plug. Cell 1 – 3.83V, Cell 2 – 3.845, Cell 3 – 3.83V and Cell 4 – 3.83V.

Is it worth to upgrade from 1300mAh to 1800mAh?

In order to make a fair compassion I used same charger (SkyRC iMAX B6 Mini) with same settings. Both batteries I used for the test had less than 10 charging cycles.


Firstly, I fully discharged both batteries, rest them for 1 hour, then charged them up at 0.5 A. As you can see in the comparison table bellow, the R-Line 95C finished the discharge process more balanced. At the end of charging, both batteries were well balanced. The two batteries remained cold during the charge.
In order to test how these two behave in the real world I used my Kopis 1 racing drone. I tried to fly them with similar amount of throttle in order to get the most accurate results.
As I'm not a Pro racing pilot, I haven't noticed significant performance dropping from 95C to 75C while flying at top speed. Also, the extra weight doesn't seem to be an issue for the 2450KV brush-less motors. Frankly, it's hard to get an objective measurement of true "C" rating without professional tools.

I ended my test flights when OSD shown 14 volts (~ 3.5V/cell). While my flight with the 1300 mAh LiPo lasted about 5 minutes, the one with the Tattu 4s 1800 mah ended after almost 7 minutes. Unfortunately, I forgot home my infrared thermometer and I can’t confirm if motors and ESCs became hotter after the longer flight.
Those who need extra flight time for their FPV racing drone, this Tattu 1800 mAh LiPo can be ordered from EU and USA (delivery from both, EU and US, is available). Now genstattu Black Friday Sale coming soon. Begins 22nd and ends 30st Nov. Don’t miss! More the biggest sale is HERE

Pros

- Well packed, with included plug protector;
- Aluminium envelope for good heat dissipation;
- Longer flight time over 1300 mAh batteries.

Cons:

- Suitable only for larger FPV drones (210mm and up).

While Tiny Whoop use 1S 150-205mah LiPo batteries and flight time is about 1-2 minutes, but use Tattu 220mAh 1S can fly about 3-4minutes, it is really the best Tiny whoop lipo battery.

What Is Tiny Whoop?

Tiny Whoop is a small FPV micro brushed quadcopter, its propellers are protected by EDF ducts that also makes it a very efficient little machine, we can fly FPV around people and kids safely. It allows some insane indoor FPV flying: chasing people, annoying your pets, cruise around the house without hurting anyone or damage anything. Compared to mini quads, the tiny size opens the horizon for new possibilities in FPV hobby. It’s more fun than I’ve ever had.

What are their advantages?

  • Tiny size, making them ideal for flying indoors, through shelves, under desks, wherever.
  • They are Efficient, with up to 4 minutes of flight from a tiny battery.
  • Acrobatic Performance, capable of flips, rolls and fast climbs due to their power to weight.
  • Robust, their ducted design also allows them to shrug off most wall impacts.
  • Inexpensive to purchase and repair. Even the bigger-budget bundles represent great value.
  • Many on the market are ready to fly, and such accessibility is rare when it comes to FPV.
  • They are just awesome fun, seriously even if you just want to fly and not tinker.

What do we need know when we build a Tiny whoop?
You can choose to go full-blown with 2S motors and batteries, or even opt for brushless motors (more on this another time!).
A typical build will contain the following parts:
  • A frame (80-100mm should be good)
  • A flight controller (the SPRacing F3 Brushed is a great choice)
  • Motors (8.5mm brushed) & propellers
  • Battery (400-750mAh; 1S/2S)
  • Receiver (depends on what transmitter you have)
  • AIO (all-in-one) camera (the FX798T is a proven champ)
You can read our Quadcopter frame, lipo battery, motor and propeller size matching table to know more about how to build quadcopter.
Batteries
Tiny Whoop use 1S 150-205mah LiPo batteries and flight time is about 1-2 minutes. Between different brands and discharge rates there might be a difference in flight time. It’s best to get loads of them. I think 10 to 15 of them is a good number to for a living room FPV racing session.
Motors
There are two types of upgrade 0615 motors sold by micro-motor-warehouse: medium & fast. Type of upgrade motors has an impact on performance and battery life. Because stock PIDs on the Inductrix main board are not adjusted to fly with neither medium nor fast so when flying in acro mode motors sound like they struggle and also there are some oscillations. I didn’t have a chance to test the stock motors with FPV gear on so can’t confirm how they perform in acro.
