-Batteries with a BMS that blocks charge or discharge current, or sets CCL to 0 when full, cause all sorts of warnings and alarms, which can often be very confusing or misleading.  +Batteries using a BMS that blocks chargeor discharge current, or sets CCL to 0 when full, can trigger a number of confusing or misleading inverter/charger warnings and alarms

-In this case the Victron inverter/charger reports overload, and time is spent in diagnosing the Victron and understanding why it gives an overload on site, but then works perfectly when on a test bench; to find the cause is a custom BMS with a DIY battery. +
- +
-Another common example is Victron requires the BMS to change the Charge Voltage Limit to restrict power flowing to the battery as it gets full. If the BMS attempts restriction using the Charge Current Limit without adjusting the Charge Voltage Limit it can cause Overcharge, Overvoltage or Overcurrent warnings+
  
 +For example the Victron inverter/charger reports overload conditions with little load, resulting in a lot of time and effort troubleshooting the fault, only for the inverter to work perfectly when on a test bench, and then discovering the actual cause is a custom BMS with a DIY battery.  
  
 +Another common problem as a battery becomes fully charged, Victron requires the BMS to change the Charge Voltage Limit (CVL) to restrict the power flowing to the battery. If, however, the BMS attempts to restrict power using the Charge Current Limit, without adjusting the Charge Voltage Limit, this can trigger Overcharge, Overvoltage or Overcurrent warnings.
