Designed and built the 4 main I/O terminals for the pack, then punched the rest of the tabs.
The final assembly of the pack with charged batteries is very tricky, and I need to carefully consider the best way to do it. the batteries can put out hundreds of amps, so a short even between adjacent batteries is going to be very bad, so I make a shaping fixture that pre-sizes the large heat shrink I have so it nicely fits over the interconnect blocks. Hopefully this will prevent any possibility of them shorting.
Will need to tweak the process as I proceed.
