Oops!

I’m having a bit of difficulty getting my packs balanced to start an experiment to see how well they remain that way. I think an easy way to do this would be to connect the 7 packs in parallel and leave them overnight to exactly equalise voltages, but this will require some new “bus bars”. I grabbed a wire this evening and held it roughly in place to check what length I need, and then POP, FLASH!

I’d absentmindedly touched the bare wire onto my pack connectors for two packs, shorting them out and instantly blowing all their fuses.

My battery project time today has been used up with replacing 20 fuses.
