Cables and Connectors

Terminal Blocks
Push-in contacts, 800V/31A, 0.2-4mm cable connectors
They also have end plates, mounting clamps and numbering on their website.
I use these for connecting the BMS to my cells. For testing other BMS’s or balancers I can quickly disconnect and switch to another device.
