More progress, the high current switch pcb's arrived today, so will make up a board and do some tests over the next week or so.



Back to the original topic, I have made up the 16 small cpu based cell modules that fit atop the main carrier board.



Have been waiting for replacement right angle 2 pin connectors to arrive, originally made the modules for straight connectors... and after fitting a couple for testing, you cannot do up the socket screws, bugger! (Kiwi Expression); anyway have made them up now with the new connectors.

These little pcbs take forever to build and I need another 64 for this project, so I think a re-design maybe is in order (new topic pending). Will get this lot going, software is almost completed, well it works 100% with 2 modules, and use it on my small battery bank for the EV charger.

Host board:

The vertical pcbs soldered to the main board with RT angle pins, don't have room to screw up the terminals.

Cheers
Mike
