Here I show how to build your own longrange lipo battery with exceptional features (large capacity, low weight) and really affordable price while those cells are of good quality (they are used by DJI!). Not sure how long this ALIExpress seller will be able to sell those cells - maybe DJI will stop this at some point?
My 4cell 3850 mah Packs weigh around 225g! and are good for 30 min flights with my planes or copters. On planes you can easily use 2 or more of these packs for even more flighttime!
Find the CELLS at ALIExpress (but not for Germany...)
(and make sure to chose the RIGHT size - 3850mah not the 2400 ones!)
Specs:
- charge up to 4.25v
- cut off at 2.8 v (land at 3v under load!)
- continuous 12A are OK, up to 28A possible (5 sec, use 2P for more demanding copters/planes)
TIPS:
Solder pads: minus pole is easy to TIN (normal solder sticks well here)
+ pole is ALU (with nickle attachment)
Good giude
