I have an F-450 quad with Emax MT2216-810kV motors and 1045 props. Currently, Im using a 3S, 5000mAh, 50C LiPo battery in it.
I’m considering to use LG HG2 18650 Li-Ion cells (20A CDR/3000mAh). The max current draw of my copter in Mission Planner logs is 25A during takeoff (nominal is 15-20A) and I have also measured it using a power analyzer (turnigy 150A, props inverted) and obtained similar values.
Since LG HG 2 is rated at 20A CDR, 30A burst, i think using it in 3S2P config can help my copter fly and i still have a safe margin of 10-15A.
Is there anyone who has experience of working with Li-Ion cells and can help me if my design is wrong somewhere?
