Battery substitute (CHEAP)

[cabinfourus]

I’ve measured over 44A with a Typhoon H-480, which I found surprising. The start up and camera loads are very small, averaging a little over an amp each. As you say, the flight loads are the big power drain, with hover and full throttle being the worst. One has nothing to assist lift while the other feeds motors always wanting more.

I have found the lipo cells that will build a 10000mAh battery.

Aliexpress has them for 14.50 each.
