Nice work Gary & Richard!
I hope it's not too much to ask but Is it at all possible to get a good resolution copy of the final artwork (1:1 300dpi+ or Gerber files) and/or schematic?
I've been making two-sided circuit boards at home for years - no nice plated holes like yours unfortunately so...
Has multiplexing ever been discussed?
I know I'm a bit late here (OK waaay too late) but it would appear that multiplexing both the LVC and BMS would reduce component count dramatically and the circuit would scale much better.
BMS charging could take place just one cell at a time at a much...
