1S 3.7V 160 mAh Turnigy Nano-tech 25-40C LiPo Battery Tests

27 Nov


The 1S 3.7V 160 mAh Turnigy Nano-tech 25-40C LiPo batteries are designed for use with small scale RC helicopters as a replacement batteries for the originals upplied with the compatible radio controlled model. The Turnigy brand by Hobby King (one of the largest online RC model stores) so far got us with mixed results when testing different batteries, for example LiPos often turn out to be with overrated specs than what they really can provide, but with the Turnigy AA/AAA NiMHs for example we got very good results. So let us see what this Turnigy Nano-tech LiPo battery can provide in our tests…

Official Battery Specifications:

– Capacity: 160 mAh
– Voltage: 1S1P / 1 Cell / 3.7V
– Discharge: 25C Constant / 40C Burst
– Weight: 4.3g (including plug & case)
– Dimensions: 39x7x11mm
– Discharge Plug: 2 Prong Align Style (Fits Align Trex 100)


We have started the tests with a 1C discharge rate (0.16A) for the 1S 3.7V 160 mAh Turnigy Nano-tech 25-40C LiPo battery and we’ve managed to get 158 mAh as a maximum capacity, or almost what the battery is rated by the manufacturer. The 2 mAh shorter than the rating of 160 mAh should not be much of a problem if the battery manages to meet its other specifications, especially considering the very good price. Up to about 15C discharge rate or 2.4A constant current load the battery seems to handle very well, then a bit of a hiccup at 20C, but still managing to provide decent capacity. And at 25C discharge rate – 4.0A constant current load the battery is no longer able to provide stable power for more than a moment before it reaches the cutoff voltage. So again we are a bit short from the manufacturer rating of the battery claiming 25C constant discharge as we can clearly see that the real rating should be more like 20C constant and 25C burst discharge instead of 25-40C.

The performance of the 1S 3.7V 160 mAh Turnigy Nano-tech 25-40C LiPo Battery in our tests:

– 158 mAh at 0.16A load (1.0C)
– 142 mAh at 0.8A load (5.0C)
– 138 mAh at 1.6A load (10.0C)
– 130 mAh at 2.4A load (15.0C)
– 111 mAh at 3.2A load (20.0C)
– 9 mAh at 4.0A load (25.0C)
