Little more work done. Built the end plates yesterday and still performing the initial cell voltage balance. The batteries are so high capacity it takes a few hours for each to bring them down 0.2 volts each! This will likely take most of the weekend. Not something you can walk away from, if the voltage gets too low you can ruin a cell. By balancing the cells so they are each within +/- 0.001 volts this will give the largest capacity. Since the BMS will shut down on high or low voltage of any cell if they are out of balance you either won't get the other cells to full charge or get a full discharge before the BMS shuts down the system. So it's worth the time to do this. Of course I could have paid 150% more and bought a drop in system from Lithionics....
Once I'm done with the balancing I'll install them in the compartment and start wiring the cells.
