Just uploaded a video to my channel with my new self-powered power shelf that I'm using to test the 20P groups I'll be using in my final battery packs:
I use one 4S20P pack to power an iCharger1010B+ and that in turn charges/discharges 1S20P groups to get capacity figures. It takes about 25% of the 4S pack capacity to charge a 1S group and then I get about 20% of that energy pumped back into the 4S pack under discharge. So I can perform perhaps a dozen charge/discharge cycles before needing to recharge the 4S pack off my solar charge controller.
