От jj60431/07/2019This is neither a 50mAh cell nor a high rate cell suitable as a LiPo flight pack for most indoor planes (despite the convenient connector).
It arrives very well protected in an individual plastic box and the assembly is good quality, but the test results are disappointing.
This is a 42mAh cell at best and ONLY if you keep the discharge below 100mA. It will be fine for very small low load applications like the Plantraco Carbon Butterfly or the TY Model Indoor Airplane Hummingbird Ultra Light.
