    90kwh battery - Multiple JKBMS

    Hey guys, we have recently taken our house offgrid. We have been at it a while but recently we switched to Prismatic Lithium cells instead of premade lithium batteries. We have arranged our batteries in 3 shelves of 16s2p. each shelf has a JK bms 200/350 can/heat (not that we need the heat in AU) any way our inverter is a victron based system with both AC and DC coupled solar. we have been keeping our charge current low (250amps) because the victron has no indication that a shelf (or more than one shelf) might not be accepting charge. so before we ramp up the charge current (we want to get to 400amps) we need to establish some feedback to the cerbo controller.

    Has anyone had any luck (other than the serial library) integrating a JKbms in to a victron system ?

    we have been taking videos of the process they are here:
