The 1S 3.7V 200 mAh E-flite 30C LiPo batteries are designed for use with small scale RC helicopters such as Blade mCPX and are the original batteries made by E-fliete for that particular model, though they are also compatible with other similar models such as WLtoys v922 or Turnigy FBL100 and others. And while these batteries are quite Ok for stock batteries for these RC helicopters the question is if they are able to meet their specifications and that is exactly what we are going to check now.

Official Battery Specifications:

– Capacity: 200 mAh
– Voltage: 1S1P / 1 Cell / 3.7V
– Discharge: 30C Constant
– Discharge Plug: E-Flight Ultra Micro


We have started the tests with a 1C discharge rate (0.2A) for the 1S 3.7V 200 mAh E-flite 30C LiPo battery and we’ve managed to get 214 mAh as a maximum capacity, or a bit over the manufacturer rating for this battery. Increasing the constant current load further to 5C, 10C and even 15C and the battery still manages to provide slightly more capacity than it is rated at. At 20C discharge it is still handing quite well, at 25C is still manages to offer decent capacity though going on the low side and at 30C, the ratting that for constant current discharge that it can handle it fails. So the real rating should be more like 20C-25C constant current and not 30C, nevertheless the mCPx helicopter still works quite well it that battery as it probably does not need 6A load. You might consider going for alternative batteries with slightly higher capacity and a bit lower constant current discharge rating in order to get more flight time.

The performance of the 1S 3.7V 200 mAh E-flite 30C LiPo battery in our tests:

– 214 mAh at 0.2A load (1C)
– 206 mAh at 1.0A load (5C)
– 203 mAh at 2.0A load (10C)
– 201 mAh at 3.0A load (15C)
– 187 mAh at 4.0A load (20C)
– 120 mAh at 5.0A load (25C)
– 7 mAh at 6.0A load (30C)
