I’ve got two of the SOK 314 AH batteries with CAN-BMS communication. I can see in victron VRM that there are two online battery modules. I try to set an alarm to notify me if the ‘number of online modules’ goes below 2 but when I test it the alarm never triggers. I disconnect the second battery and VRM correctly identifies that there is only 1 module; but the alarm still does not go off. Bug? Thoughts? Am I somehow configuring incorrectly?
I haven’t tried that one yet … but I’ve noticed that with DVCC enabled, I frequently get alarms on the Cerbo for high cell voltage (I have 2x SOK 314Ah installed on a boat with shore charging and alternator charging).
When I get the high voltage warning, then that pack blocks charging. However, there is no Cerbo alarm for a pack blocking charging (disconnecting)… would be happy to hear about your experience with these cells… the cells themselves seem to hold up very well under high current (3000W inverter) but I have some concerns over the BMS and how it behaves with DVCC enabled…
I also get the high cell voltage alarms; but I do not have DVCC enabled. I was guessing those were due to battery cmos disconnect. I only see them when the battery reaches 100% SOC.
I’ve disabled DVCC on mine. It seems the SOK signal modulates the desired current as they become full; but Victron seems to want a modulated voltage.
