Dyson V6 Extended Life Battery Replacement

Is your Dyson V6 or DC35 battery getting tired and not lasting very long? Well, your lithium-ion battery may need to be replaced. These high-performance batteries only last around 500 charge cycles until they start to lose their charge.
Usually, this is not a big deal as you may only use your vacuum cleaner every few days. This means your battery should last around 4 years.
But you have to make sure you get the correct type of Dyson V6 extended battery  This is because there are 3 versions or redesigns of batteries for the different types of Dyson cordless vacuums. I will explain the differences further down in the article.

How to tell if you Dyson Battery is failing?

The biggest telltale is the runtime. Usually, you should get around 26 minutes of vacuuming on the standard setting. By pressing the boost button on the back of the Dyson V6 you will get extra suction but your runtime will be reduced to around 6 minutes.
This is a big difference and it shows how much power the boost function is pulling from the battery.
If you find that your cleaning time is less then you should look at a few simple problems before replacing your battery.
  • Are you stuck in boost mode? Shown by the blue indication on the back. Press the button while running to take it out of boost mode.
  • Do you have a blockage in the vacuum tube or canister? Empty the canister trap and clean any blockages in the tube.
  • Is there a jam or excess hair wrapped around the motorized v6 brush bar head? Remove the V6 head and remove any hair or string. 
  • Is your wall charger plugged in and turned on?
  • Is your cloth filter clean on the top of the V6 hand stick? 

How to remove the battery from Dyson V6 cordless.

The only tool you will require to remove the Dyson V6 battery is a Philips screwdriver.
dyson dc59 battery removal
First, make sure that you empty and remove the rubbish cannister. Then unscrew the 2-star screws from the top and bottom of the handle and then pull out the battery. It may be a little stiff the first time due to all the years of dust build up in the handle.
Make sure to only replace the same type and size of Dyson V6 battery. It should look identical and slide right in with a slight tap to seat it fully.
how to remove dyson replacement battery dc59
If you are having trouble inserting it have a look why. Has something fallen into the handle slot or is the battery protector contacts cover still on.
Don’t forget to replace the two screws which will secure the new battery to the V6 handle. It’s now time to fully recharge your new battery before use.
Charging should take around 3 1/2 hours from a fully discharged battery. A blue light will illuminate when charging begins and turn off when the battery is full. It’s now ready for cleaning duties again.

Difference between DC35 Vs Dyson V6 Cordless Battery

These two batteries from the Dyson DC35 and the V6 are not interchangeable. They are a slightly different shape. Both use the high power internal lithium-ion batteries and replacing the battery pack with a new one is really easy.
Lithium-ion batteries only have around 500 charge cycles until they start to degrade. Now, this doesn’t seem like much but if you only use your battery-powered vacuum cleaner every second day you still will get around 3 years of usage.
The symptoms of the Dyson V6 battery failing are less runtime than the usual 20+ minutes or the battery will not charge at all. Just remember that using the power MAX boost vacuum button will only give you around 6 minutes of runtime due to the extra power draw.
But it sure does have a great deal of extra power in the max position. This is why its great to carry a spare.

Tattu Dyson v6 extended battery replacement 3000mAh– DC58, DC59, DC61, DC62, DC72, and DC74

The Dyson V6 uses another redesign of the previous version batteries. It’s a shame that if you have two different cordless handheld vacuum cleaners you would need 2 different batteries.
The Dyson replacement battery dc59 shown above is the current model for all V6s handsticks or cordless vacuums. I wish they would stick with a simple naming method for their vacuum cleaners.

  • Lipo battery, 3Ah Real Capacity, 22.2V, which is made with high-quality lipo.
  • Compatible With Dyson Models: Dyson V6, Dyson 595, 650, 770, 880, DC58, DC59, DC61, DC62, DC72, DC74.
  • with weight only 338g but more capacity than the original battery.
  • 30% extra run time than the original 
Having a spare or two is very handy, and it only takes a minute or two to remove the screws and push in a new Dyson replacement battery dc59. Many people think that this is like maintenance or should only be done at a repair center. Anyone can do it, in fact, my 8-year-old daughter removes the battery herself when she cleans the house for some pocket money.
There is no real way to charge the battery when it is out of the V6 vacuum cleaner. That’s why we do the quick swap out and leave the screws out until all of the spare batteries are charged and then we screw in the final battery.
This was the cheapest way I could work out to get extra life out of my Dyson V6 rather than buying another vacuum cleaner. I guess this is the future now with them scaling back their research on corded vacuums and diverting their whole attention the cordless handsticks.

Tattu FunFly LiPo review: Perfect for daily practice

GensTattu recently launched a new product line, called “FunFly”. Unlike the “R-Line”, it is available only in 4S version and with two capacities. Both, FunFly 1300mAh and FunFly 1550mAh are 100C rated. In the past, we already reviewed couple of Tattu LiPos, including the R-Line HV 1550mAh 100C and now it’s time to have a closer look on the new Fun Fly series.
GensAce claims that their new Tattu Funfly series was specifically designed for daily training and freestyle, which requires medium performance. In order to allow long service time (many charging cycles) it has standard LiPo cells (~3.7V) not high voltage ones (~3.85V) ones.
Tattu FunFly features and specs:
– Available in 1300mAh and 1550mAh versions;
– Designed for daily training and freestyle;
– 4 cells of 3.7v. Total voltage of 14.8V;
– 100C discharge rate;
– JST-XH charging plug;
– XT60 discharge (drone) plug.
Tattu_FunFly_review_introductions
Tattu FunFly batteries review:
Like usually, GensAce did a great job regarding packaging. In order to avoid any damages that can occur during shipping, the batteries came in a large box with lots of foam peanuts.
Both LIPOs (1300 and 1550mAh) come in the same type and sized box. Along the battery, a safety instruction is included as well. They arrived half charged (3.81v/cell – optimal voltage for long time storage).
Tattu_FunFly_review_box_content
While the FunFly 1300mAh 4s 100C measures around 73 x 35 x 28 mm (L, W, H) and weights 153 grams, the FunFly 1550mAh 4s 100C measures around 72 x 35 x 36 mm (L, W, H) and weights 178 grams. BTW, the price difference between them is only 1 dollar.
Tattu FunFly vs Tattu R-Line
Being a bit confused whats the sens of a new series, when the R-Line does such a great job, I contacted the manufacturer in order to find more insights about their Fun Fly LIPOs. Firstly, I got this feedback “Our Funfly Batteries are mainly for daily practice and for those who fly for fun. Different recipes with Tattu R-lines” Asking again for more details “Sorry, but I really could not explain more. The FunFly batteries comes out for the pilots who fly for fun. I mean the punch of FunFly may be less than R-lines in some points“.
Tattu_FunFly_vs_Tattu_R-Line
Tattu R-Line VS Funfly
Tattu FunFly review: Test
Prior to any tests, I performed 3 circles of charging/discharging. As you can see in the comparison table bellow, both 1300 mAh and 1550 mAh LIPOs finished the charging process at 16.81V. The cells were almost perfectly balanced (4.20~4.21V). While the 1300 mAh LiPo ended with 1387mAh, the 1550mAH did it with 1597mAh. Both batteries remained cold during the charge (20~24 °C).
Test data
Tattu_FunFly_review_testing_tools
For the real world tests I used my Kopis 2SE drone, which is a powerful machine that can heavily stress any LIPO.
While the FunFly 1500mAh provided bout 1 minutes extra play time over the 1300mAh one, I felt like the extra weight made the drone less agile. Normal flight seemed the same, but flips/rolls seemed faster with the lighter pack. Both LIPOs have stable power to perform super fast punch-outs.
Tattu_FunFly_review_test_Kopis_2SE
Last but not less important, at the end of my test fights, the battery packs remained well balanced in both cases.
Considering that these batteries are less than $20 and perform almost like R-Line packs, they seem like a good deal. Both versions can be ordered from here (you can opt for US and DE warehouse).
Tattu_FunFly_review_verdict
What I liked:
– Excellent build quality;
– Nicely priced;
– 100C, ultra high discharge rate;
– US/EU availability.
What I didn’t liked:
– Available only in 4S configuration.

LiHV (4.35v) vs Lipo(4.2v) for RC Model

We have been hearing good things about LiHV batteries, which is reportedly better than traditional LiPo, especially for mini quad racing. I ran some tests and tried to find out which battery is better.
Many thanks to Aircraft-World.com for sending me the Hyperion HVLi batteries for testing.

What is LiHV battery?

LiHV (or HVLi) stands for “High Voltage LiPo”. It’s a similar to LiPo battery but allows you charge it up to 4.35V per cell safely.
When you charge LiHV batteries like standard LiPo to only 4.20V per cell, they perform pretty much similar. However when you charge them fully to 4.35V per cell you get the following advantages:
  • With a fully charged HVLi battery, voltage is higher than normal LiPo’s (on a 4S, HVLi is 17.4V,  LiPo is 16.8V), therefore your motors will run harder at higher RPM, and your quad can fly faster theoretically
  • Secondly, LiHV can store more energy than LiPo per weight, so theoretically (again) you get longer flight time. Hyperion (the company that makes these HVLi batteries I am testing) states there is a 10% increase in capacity than standard LiPo’s of the same size and weight
  • Lastly, good quality HVLi has lower voltage sag on high throttle

Can you charge your normal lipo to 4.35V?

So you might wonder: “can I over-charge my normal lipo to higher voltage like 4.30V or even 4.35V, to get more power and longer flight time? ” The answer is NO!!! That’s extremely dangerous and very likely to cause fire because of the different cell chemistry.

How to charge HVLi?

Before you buy any HVLi batteries, you should check your charger first as not every existing charger can charge HVLi batteries.
Some chargers don’t have HVLi as a battery type, but allows you to charge up to 4.3v/cell. Still, It’s best to have a charger that has a setting for LiHV specifically, for example this IMAX X150.
You should NOT charge HVLi together with standard lipo, when you over charge LiPo over 4.2V per cell you might get a fire. Chargers are unable to detect whether you have plugged in HVLi or normal LiPo so be extra careful not to mix them together.

HVLi Batteries I am testing

These Hyperion HVLi packs come with standard XT60 Main connectors, with JST-XH Balance connectors. The discharge lead is 14AWG silicon wire.
Hyperion 1800mah 4S HVLi battery 4.35V 40-80C
When comparing to normal LiPo of the same capacity, LiHV’s are smaller and lighter due to the higher energy per weight.
  • Hyperion 4S 1800mAh 40C – 178g
  • Turnigy Nano-Tech 4S 1800mAh 65C – 228g
Hyperion 1800mah 4S HVLi battery 4.35V compare to turnigy nano tech size
And here is the smaller 1400mAh pack.
Hyperion 1400mah 4S HVLi battery 4.35V 40-80C
Hyperion 1800mah 4S HVLi battery 4.35V compare to drone-lab size

Testing and Comparing of HVLi and LiPo

So with the help of my KISS FC + KISS ESC 24A setup, I was able to monitor voltage and current draw at the same time while flying.
kiss fc osd display esc telemetry data hyperion-hvli-lipo-excel-battery-data-analysis
I tested and compared the Hyperion 4S 1800mAh and Turnigy Nano-Tech 4S 1800mAh. I ran the test twice, the first time I was just hovering, and the second time I did some med-high speed cruising.

Hover Test

Here I hovered the quad at one place, and only landded when “consumed mA” reached 1800mA – the specified battery capacity. (I removed the GoPro to get a bit longer hover time)
  • Hyperion: 10:45
  • Turnigy: 9:09
I was expecting they would land at about the same time, given both are the same 1800mAh capacity, but interestingly NO! The Hyperion lasted about 96 seconds longer than the Turnigy.
My guess is the weight of the batteries, the Hyperion is 50g lighter than the Turnigy, and the motors pull less current when just hovering. The power graph confirmed this, as you can see the quad has to work harder (higher power) to stay in the air when carrying the extra weight.
Another thing to notice is the voltage of the batteries throughout the whole discharging cycle. The voltage of the HVLi is higher than the LiPo initially, but towards the second half of the process, it was gradually getting closer to that of the LiPo.
Fun fact: After we have drawn 1800mA from the Turnigy Nano-tech, its voltage was still pretty high at 14.4V (3.6V per cell). That suggests it actually might be larger pack than specified by manufacturer. (maybe 1900mAh?)
FormatFactoryhvli-vs-lipo-battery-hover-test-graph-capacity-voltage-power

Fast Flying Test

In this test I was flying around with 70% to 80% throttle constantly. The higher voltage improved the responsiveness and speed of the quad. You can see that from the power graph, the quad was able to pull out more power from the LiHV than LiPo overall.
However I didn’t notice much improvement on flight time compared to the Nano-Tech LiPo, probably because I was pushing the quad too hard.
Similar result to the hover test, where we see higher voltage at the beginning, but they converged towards the end. That suggests the battery would give your motors higher RPM and less voltage sag, thanks to the higher initial voltage, but probably similar performance to the LiPo’s in the 2nd half of the pack. I think this is something you need to take into account when doing endurance races, where you need to decide when is best to change batteries.
*Note that the Turnigy battery I was comparing against with is nearly a year old so discharge rate is worse than new packs. I don’t have any new 1800mAh LiPo packs so that’s it.
FormatFactoryhvli-vs-lipo-battery-flight-test-graph-voltage-power

HVLi for your Fatshark Goggles

I also tested a 2S HVLi pack, which is designed for Fatshark FPV goggles – 2S 1300mAh 2C-4C. They look exactly the same to the original LiPo pack that comes with the Dominator Goggles I have, but the HVLi can power on your Goggles for much, much longer!

Hyperion 1300mah 2S HVLi battery for fatshark FPV Goggles connectors
I tested the following 3 x 2S batteries, and here is the result:
  • Fatshark 2S 1000mAh (Stock Lipo) : 0:50:10
  • Turnigy 2S 1300mAh: 2:37:26
  • Hyperion HvLi 2S 1300mAh: 2:52:42
The Hyperion is able to power the goggle on for nearly 3 hours straight! Very impressive :)
Note that I did this battery mod on my goggles batteries for easier charging.

Where to buy?

Where to find the high voltage lipo battery for sale? go to Genstattu Lihv Now, find LiHV for RC cars, FPV etc!

Update Feb 2017 – Longevity Issue

After some use of these HVLi, they seem to have pretty short life cycle: after about 30-40 discharge cycles, the cells are starting to swell, and they don’t hold full charge anymore. They get really hot after a fast session. Normally for a decent standard LiPo they should hold up 300+ cycles.
So at this point, I don’t think I will buy anymore HVLi for day to day flying and practice due to the lack of longevity. However for special events like races, I might still consider them for the outstanding performance.
