The 2S 7.4V 800 mAh Gens Ace 20C LiPo batteries are intended for use in various RC models such as helicopters and planes. These compact LiPo batteries have a pretty high discharge and charge ratings that we need to confirm in our tests. What is important to note is that the maximum discharge rates mentioned in the specifications are for quite high Amps and the small cables and connectors of the battery may not be able to handle them well.

Starting the tests with a 1C discharge rate (0.8A) for the 2S 7.4V 800 mAh Gens Ace 20C LiPo battery we’ve managed to get 793 mAh as a maximum capacity which is a bit short from the rated capacity of 800 mAh though at less than 1% it is not a problem. Going for higher discharge rate the battery still manages to offer very good capacity even at 20C it handles pretty well with 749 mAh useable capacity. The problem however is that at 20C constant current discharge rate the cables of the battery get way too hot, we’ve measured 98 degrees Celsius and that is way too high. The cables getting hot are just an indication that the current passing through them is more than what they can safely handle.

The performance of the 2S 7.4V 800 mAh Gens Ace 20C LiPo Battery in our tests:

– 793 mAh at 0.8A load (1C)
– 784 mAh at 4.0A load (5C)
– 774 mAh at 8.0A load (10C)
– 765 mAh at 12A load (15C)
– 749 mAh at 16A load (20C)

While the 2S 7.4V 800 mAh Gens Ace 20C LiPo batteries are capable of handling a constant discharge rate of 20C as their specifications say the battery cables used are not desgned to properly handle the 20C constant discharge rate!
