Mega Power Supply for field charging!

This is a project I did with great help from my pal Birger. It's a do-it-yourself power supply project! It powers my field chargers to charge my Lipos for my RC Planes. Massive 100,000 mA of Lithium-ion rechargeable power! On-board balance boards keep my Lithium-ion's happy. There are 120 each Samsung 50S 21700 5000mAh 25A cells.
