Tattu R-Line HV 1550mAh 4S 100C Review
May 12th 2018
The GensAce Tattu 4S High Voltage LiPo battery with 1550mAh capacity offers very long flight time for FPV drones. The 100C discharge rate gives you enough power for impressive acceleration and crazy punch outs. In addition to the above, the Tattu R-Line 4s 1550mAh adopts high voltage technology. Let’s discover more thoughts in our review.
In a nutshell, high voltage batteries are like nitro for racing cars. While standard LiPo packs can be charged with up to 4.2V/cell, the Tattu HV LiPo allows to safely charge it up to 4.35V per cell. While a fully charged standard 4s LiPo pack has 16.8V, a HVLi battery pack has 17.4V. Furthermore, theoretically, LiHV can store more energy than LiPo per unit of weight. Unfortunately, this increased energy density seems to have a negative impact. Many FPV pilots complain that LIHV batteries have shorter life cycle than standard LiPo packs.
As usual for Tattu’s R-Line, battery comes well packed with charging plug protector and safety instruction. The box in which came the 1550mAh 100C is almost double compared to the one in which the 1300 mAh HV 100C is packed.
Battery pack measures around 75 x 35.5 x 38 mm (L, W, H) and weights 188 grams. Most hobbyists, when they are choosing LiPOs for their drones, are looking for the cheapest ones. This is not necessarily wrong, but when it comes to racing quads they should be considering performance, weight, and size of the battery as well.
When it comes to LIPO performance, the most important thing is how it behaves on the drone. Besides the raw specs (voltage, storage capacity and C rating) it is very important the weight/power ration. During my LiPo tests, I noticed that even the shape of the battery pack can influence the flight performance and total flight time.
Like in the case of my previous LiPo reviews, I used my Kopis 1 drone. It is a very powerfull machine that can heavily stress the battery. Allowing super-fast continuous flips and rolls, it showed up the advantage of the high “C” ratting.
While I got about 1 minute of extra flight time with the Tattu 4S 1550mAh 100C HV over its smaller brother, I felt like the drone was less agile. It seems that the extra weight and larger size had some negative impact on the flight performance.
Those who need advantages of a LiHV battery, this one can be ordered from here (delivery from both, US and EU, is available). There is also available a newer version with detachable balance cable. This feature will cost you extra 5 bucks.

Tattu 4S 1550mAh 100C HV LiPo battery review
Disclosure: I received this drone battery as part of a product review collaboration with Gens Ace. Although the LiPo was offered for free, all opinions in this article remain my own and I was in no way influenced by my partner.
As usual for Tattu’s R-Line, battery comes well packed with charging plug protector and safety instruction. The box in which came the 1550mAh 100C is almost double compared to the one in which the 1300 mAh HV 100C is packed.

Charging test and real world performance?
Prior to any tests, I performed 5 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 17.41V. While the 1330 mAh LiPo ended with 1460mAh, the 1550mAH did it with 1789mAh. Both batteries remained cold (21~24 °C) during the charge.

Besides the raw specs (voltage, storage capacity and C rating) it is very important the weight/power ration.
