Tattu R-line battery review: 95C, more punch for your drone

Tattu R-Line 4s 1300mAh Li-Po battery review

Frankly, being my first Li-Po review, I didn’t know how 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 evolved this fast. The biggest advantage of lithium polymer (LiPo) batteries is that they have about four times the energy density of nickel-cadmium or nickel-metal hybrid batteries.

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

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 capacities depending on the size of the cell.

Tattu R-Line review - Advantage of LiPo batteries

IMHO, besides weight, the discharge rate (or “C” rate) is one of the most important specs of a Li-Po battery for racing quadcopters. I remember that a 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 the partner in no way influenced me.

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.

Tattu R-Line battery review - Whats inside the box

Battery measures around 36 x 72 x 32 mm (W, L, H) and weighs 163 grams. Due to the thick discharge cable and aluminum envelope, the Tattu R-Line weighs about 10 grams more than other 4s Li-Po batteries with the same capacity. As you can see in the image below it has a 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);
  • The maximum burst discharge rate of 190C;
  • JST-XH charging plug;
  • XT60 discharge (drone) plug;

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

Tattu R-Line 4s LiPo review - Cable thickness

I received about half of the batteries 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.

Tattu R-Line 95C 1300mAH 4S review - Charging curve

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 the battery level reached 16.81V (4.2V / cell). The Li-Po battery did not heat up at all and the stored capacity was 1258 mAh.

The 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, and punch-outs are even more impressive than with the stock battery. I could say that flight time was better, but this could hardly be determined because every flight is different. Full throttle drains the LiPo battery much faster than just hovering.

Trying a few flips, I had some crashes, too. The battery remained intact and safe for further use.

Pricing and availability

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

REVIEW OVERVIEW
Price/value ratio
Build quality
tattu-r-line-battery-reviewAs 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). <br> Pros<br> +Available to order directly from EU (Germany) and US warehouses; +95C, ultra-high discharge rate; +Well packed, with included plug protector; +Aluminum envelop for good heat dissipation and some crash protection.<br> <br> Cons<br> -Heavier than similar batteries.<br>

1 COMMENT

  1. Very good review, you are a very serious and responsible person, you spend a week time to do this review, it is very admirable. You received all the batteries about half charged (47%), because it is most suitable for storage battery.
    Good job!
