Now most drones are all using Lipo battery, without the Li-Po technology drones could have not evolve this fast. Biggest advantage of lithium polymer (LiPo) batteries is that they have about four times the energy density of the nickel cadmium or nickel-metal hybrid batteries.

As you probably already noticed, Li-Po batteries have usually 3 ~ 4 marks: number of cells (like: 4s), voltage (like 14.8V) discharge rate (like: 95C) and charging rate (not always specified).

In order to obtain higher voltage or higher current, Li-Po arrays are made from several cells, serially connected respectively in parallel. Li-Po cells have always 3.7V nominal voltage but can have different storing capacity depending on the size of the cell.

IMHO, besides weight, the discharge rate (or “C” rate) is one of the most important spec of a Li-Po battery for racing quadcopters. I remember that few years ago Li-Po’s were rated with max 15C. Now, Gens Ace Tattu R-Line (Racing-Line) promises 95C, higher “C” means more punch respectively more fun.

Disclosure: I received this battery 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.

Although I requested only one R-line 95C 4s Li-Po, I received 3 pieces. Nice surprise, thanks again. Batteries were well packed in a huge box. Each battery comes with its own safety instructions and charging plug protector.

Battery measures around 36 x 72 x 32 mm (W, L , H) and weights 163 grams. Due to thick discharge cable and aluminium envelope, the Tattu R-Line weights about 10 grams more than other 4s Li-Po batteries with same capacity.

As you can see in the image bellow it has similar size and form factor with the Walkera F210’s stock battery (1300mAh 4S lipo).

I received all the batteries about half charged (47%). I measured 15.34V on the XT60 plug. Cell 1 – 3.84V, Cell 2 – 3.84V, Cell 3 – 3.82V and Cell 4 – 3.84V. BTW, 3.8 V/cell is the voltage recommended for storing Li-Po batteries.

Tattu R-line 4s 1300 mAh review: Test

Being a responsible guy (and also afraid of explosions), before any test I read the instruction guide. I know that Li-Po batteries require special handling but it was shocking to read that I need to use a fireproof cement concrete bunker to store the battery : -S.

After I discharged the Tattu R-line 4s 1300 mAh to about 10% I started to charge it with 0.7A using my SkyRC iMAX B6 Mini charger. The charging process stopped after about 2 hours, when battery level reached 16.81V (4.2V / cell). The Li-Po battery did not heat up at all and the stored capacity was of 1258 mAh.

Second day I went out with my Eachine Racer 250 Pro and  Walkera F210 racing drone in order to do some punch tests.

The Tattu R-Line 4s 1300mAh battery performed very well, punch-outs are even more impressive than with stock battery. I could say that also flight time was better, but this could be hardly determined because every flight is different. Full throttle drains the LiPo battery much faster than just hovering.

Trying few flips I had some crashes too. Battery remained intact and safe for further use.

Summary

As I didn’t have fancy gears to measure the exact spec of the battery, I can’t confirm that the R-Line truly delivers 95C but, in my opinion, if it has only 75C is still far enough for most of the racing drones.

I liked that the battery was carefully packed and it came with detailed safety instruction (En, DE and CH).

Because lately ordering Li-Po batteries from China became more and more difficult, is good to know that now you can order it directly from Gens Ace Europe or US warehouse.
