I am building lithium battery packs and want to connect the power lines securely to each pad on the printed circuit board of the battery monitoring system (BMS) board. I am using braided wires with silicon sheathing to connect to each pad.

The wires need to be removable so that field servicing the batteries is possible without the need to solder/unsolder each wire.

I'd like suggestions on possible connector solutions - I've been digging through Digikey but no joy. Here are views of the BMS card. Thanks!

  • \$\begingroup\$ Do you know how much current is expected through the connectors? \$\endgroup\$ – jonathanjo Jan 27 at 18:34
  • \$\begingroup\$ I would expect up to 40 Amps from the main power connectors & significantly less from the others as I assume they're mainly for monitoring battery voltages but I could definitely be wrong. \$\endgroup\$ – cpuguru Jan 27 at 19:35

How about a ring crimp connector?

Nice and robust and, properly screwed on, won't come off. Or perhaps a spade connector. Pictures at Wikipedia. Long catalogue at TE
