Hey guys,
Just bought Aldi 20v 5ah/40v 2.5ah battery. £24.99 with 2 years warranty. Perfect to take on airplanes (90wh). Works out to £2.50 per cell if you're harvesting. These costs £30 before covid!
Im a bit confused on how to wire 1x 40v 2.5ah battery to the controller like this guy did:
From what i can see, wiring b1- to b1+ gives you 20v, and b2- to b2+ gives you 20v as well, watch from 47:50 -
So im guessing i need to wire b2- to b1+. Then for the controller it will be b1- and b2+ for 40v 2.5ah? Would 10s1p be too harsh on the cells? Better use 2x batteries in parallel or 2x batteries in series for 40v 5ah?
