Putting final configuration parameters in a new system and noticed a difference in voltage measurements between a Victron SmartShunt and a JK B2A24S15P.
Battery measures 53.33v between cells 1-16. (Using two different multimeters.)
BMS measures 53.33v.
SmartShunt measures 52.89v and manual measurement confirms that.
Measurement across the B- & P- of BMS shows 420mv. (Using two different multimeters.)
The math between 53.33v & 52.89v is 440mv (not 420mv) but I can accept a 20mv measurement error, connection and cable losses.
Is that sort of voltage drop in a JK BMS to be expected?
What do other forum members experience wrt BMS voltage drop?
Note that the SmartShunt is connected to the P- side of the BMS.
