SOK Bluetooth BMS current accuracy?

[turkington]

I have noticed that the current reading from the new BMS (Bluetooth version) in the 206Ah SOK is about an amp higher than that reported from my Victron shunt. I have zeroed the current on the Victron shunt and tend to trust it's reading more than the BMS. When the battery is disconnected the BMS reads 0A flow and I've tried to zero the current but it wants a parameter for Dynamic current and won't proceed.

My gut says that the BMS reading for SOC is an estimate as well as the Victron shunt but I can't explain the 1A more current reading from the BMS... IS anyone else experiencing this?

Same effect on charge as observed on discharge... SOK BMS reads ~14% higher on current.
