And there is a good Lipo battery very good!

Lipo battery Discharge Test By Bulb

Lipo battery discharge is a trouble things, sometimes we plane to fly outdoors with our full charge battery, but at this time you have some other reasons had to cancel this plan, you may wait a long time to flight, so a full charge lipo battery is not good for storage, Lipo battery guide said the voltage for a long time storage should be 3.6V~3.9V range per cell, so we need to discharge the battery to reduced the battery’s voltage. And there is a test about used lamp to discharge the battery.

I have bought a used Gens Ace 2600mAh 6S battery on GensTattu, this is my first time to use Gens Ace 6S lipo, but it is a used battery, the new battery need about 50$, I bought it or my Protos 500.

There are two bulbs, put them in series.

First: charge the battery; I used a 12V power to charge my battery, so the max input power is about 180W, max charge current is 7A.

This is the Internal resistance of battery.

It spend about 17mins to finished fast charge.

Because this battery is an used, I spend about 5 mins to charge my battery’s voltage form 3.8v to full, the capacity is about 1560mAh.

This is a 2600mAh battery, according to the relationship between voltage and capacity of the lipo battery, 36% capacity’s voltage is about 3.8V, the real capacity is  2600 * 36% = 936mAh. So in theory, starting from this voltage charge until full charge in about 2600-936 = 1664mAh.

Using 6S battery discharge, the Lamps are very bright.

But after a short time, the lamps get very hot;

The battery’s voltage drops quickly,

After about 20 minutes, the battery voltage drops 3.75V, you can see the b cell 3 and cell 5 still uneven,

Pull the bulb and the voltage back to 3.83V.

Then plug in the bulb for about less than 1 minute, the battery voltage below 3.71V, pull the bulb the voltage back up to 3.8V, then use the charger storage balance feature to finish it.

Through this test, I get two tips:

1. If the battery is new and the balance is good, the charger’s storage mode should be not used after the discharge has been completed;

2. In the course of the discharge, the balance plug can be connected to the battery tester, and the alarm voltage of the battery tester is set to 3.7V, so that when the discharge reaches the value, the electric battery tester alarm will be taken!

In general, use the bulb to discharge is cheaper and faster than chargers, and it will not cause any loss. If you don’t want to cost to much, this way is as good as a cheap and practical solution, it is worth a try.

Build a Fast FPV Racing Quadcopter?

If you want to win a FPV drone racing, there are two important points: one is your superb flight skill, and another is your good FPV drone. About flight skill, you need to do more flight training, but get a good FPV drone is easier than flight skill. So How to build a fast FPV quadcopter?

What’s a good FPV drone? I think a good drone must come with high speed and large acceleration. For racing drones, the acceleration is the most important. As we know FPV drone race track is very short and many track corners. As soon as possible to lift the speed is the most important after the drone pull out the track corner, so it is not a large thrust motor can help you to win a racing, you need a reasonable collocation scheme for your drone.

In the past, I used QAV 250 frame equip with 1806 motors and 3S Lipo battery can fly very fast; and now I use 2205/2305 motor, come with small and light frame, DALRC6045 propeller, the speed get 185km/h. So how to choose the FPV drone parts?

Motor:

I have used many different motors, and these are some of I used.

• 2205 motors: equip with dalrc5045 3 propeller, their thrust is about 1200g(motor’s weight is about 30g, 4 motor is 120g)
• 2206 motors: I have used it, the weight is too heavy, hard to turn the corner, and the speed is not increased significantly;
• 2305 motors: this is my new test motors, and the thrust is very good, they’re super smooth and have a good power!

Frame:

I have three requirements for select the frame:

1. Light weight;
2. Small wind resistance;
3. Strong and solid;

In the past, I sued dalrc220 frame because it is strong and solid, and needn’t consider the weight, now I like the new frame xr220, because it is light, strong solid and small wind resistance.

ESC:

I think the most ESCs have no difference, the program are similar, you just need consider the price. I’m using the Tattu ESCs, in order to match my Tattu quadcopter motors.

Lipo Battery:

To flight fast, a good lipo battery is very important; low C rate can’t discharge high current, if you want to flight fast, you need at least 60C or more lipo battery. How to choose high discharge rate lipo battery? I recommend you can choose Tattu battery, best power delivery, autonomy, reliability, long life and less sag than any other lipos, and most FPV pilots are using their battery.

I have built many FPV quadcopter, and this is one of my FPV quadcopter’s build parts;

• Frame: XR 220;
• Motor: Tattu 2305 2450KV motor;
• Propeller: dalrc 5045 3 blade propeller;
• ESC: Tattu BLHeli_S 30 AMP ESC;
• Camera: Hsh1177;
• Lipo Battery: Tattu 1300mAh 4S 75C Lipo battery;
• Flight Control: F3
