You may have seen my recent blog on Connecting EV Batteries. This generated a lot of interest, particularly in what was not covered- what about connecting smaller Lithium batteries? In the EV world, Lithium batteries (specifically, individual cells) are rather large, hulking items that require large connectors both for mechanical…
