Large Portable Battery

18 July 2019


This is a fairly large, briefcase style, portable battery pack that can be used for drone operations, camping, or emergencies. The pack is comprised of 3 cells of 60 18650 LiIon batteries, for a total of 180 batteries and about 1.6kw of power.

I spot welded the pack myself using a spot welder I built from Malectrics Arduino Spot Welder Kit.

The self-contained battery unit has a BMS capable of 100A output, many USB ports, 12v out, a 1000w inverter, and an automotive fuse board.
