Hope someone can help… The issues I’m have are hard to explain… I have 4 12v 100a bluetooth/heated SOK’s hooked to a Victron Multiplus ll. When on shore power they all read 100% and the CMOS is gray and everything works fine. If I unplug from shore power - and continue to run the A/C in my Motorhome on solar/battery, the Multiplus shuts down the AC power and the ‘low battery’ and ‘overload’ red lights on the Multiplus come on. The SOK-BMS app shows BOTH the CMOS and the DMOS have switched to gray and only the DC power works in the Motorhome. Then, if I plug back into shore power, eventually the CMOS and DMOS go to green. Is this an issue with my SOK batteries or with the Victron Multiplus? Any solution/suggestions are welcome. TIA, Craig.

I am seeing a similar problem.
- 2 SOK 100-Heated in parallel
- A BMV 712 battery monitor
- A 12V, 2K Multiplus.
If the Current as read by the BMV712 gets much above 100A, the batteries shut down. (With 2 in parallel, I should be able to draw 200A)
When I put a load on that draws about 80A as read by the BMV712, the BMS in each battery reports 75A (for a total of 150A). This tells me the current sensor in the BMS is off by nearly a factor of 2!!
