  Hello, I have a 4S unit. I am using the REC software. On the screen, I see the Vbat meter showing 34 volts at full scale deflection. I would expect the full scale to be around 18 volts. Are the full scale ranges on Vbat and Ibat adjustable? original post lost during upgrade, reposted @patrick-miller

  I am not sure if this configurable or not.  Al, any ideas on this one? Rick OGSS @al-thomason

  Hello,   I do not believe the scale dynamically adjusts  - and is fixed for both 12v and 24v deployment.  The Color bands seem to be the same situation.

  Why would full scale for a 4S configured BMS be set at 34 volts?  Isn’t 4S by definition a BMS for 4 cells with a max voltage somewhere around 18 volts no matter the chemistry of the cells? This would seem to be a bug to me.
