Tattu R-line 1300mAh 4S Battery Review With Walkera F210

Do you like it ?0

Frankly, being my first Li-Po review, I didn’t know hoe to start it. I took the Tattu R-line 4s 1300 mAh battery in my hand several times hoping for inspiration. Nothing, it was like holding a banal brick. Then, I realized that 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.

Tattu R-line 95C, 4S Li-Po battery review

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 (4s, 40C, 1300mAh).

Tattu R-line 4s 1300 mAh battery technical specs

  • Higher capacity than comparable size packs;
  • Designed for professional drone FPV racing;
  • No memory effect;
  • Minimum of 1300 mAh storage capacity;
  • 4 cells of 3.7v. Total voltage of 14.8V;
  • Total power of 19.24 Wh;
  • Ultra high discharge rate of 123 A (95C);
  • Maximum burst discharge rate of 190C;
  • JST-XH charging plug;
  • XT60 discharge (drone) plug;
  • Net Weight: 172.6 grams (±20g);
  • Dimensions: 72 x 36 x 32 mm (L W H).

Charging wires are 22AWG, which according to Wikipedia?can handle up to 7 Amps. Note: Tattu allows to charger their R-Line 4s 1300mAh battery with max 5C, 5 x 1.3 = 6.5 Amps.

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 drones 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.

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 GensAce Europe or US warehouse.
