I am trying to configure my JBD bms with Venus OS (rpi) Large and dbus-serial battery
LouisVDW suggests setting the
MAX_CELL_VOLTAGE to 4.0v (so 7s would be 28v)
MIN_CELL_VOLTAGE to 3.6v (so 7s would be 28v)
I have set the dbus-serial battery driver to these parameters,
Now to change my JBD bms settings using SShoecrafts awsome JBDtool.
I can see that MAX_CELL_VOLTAGE is FullChargeVol listed below as 4150
MIN_CELL_VOLTAGE is i guess ChargeEndVol currently 3000
My question is What other parameters do i need to change to account for these lover voltages?
I guess BalanceStartVoltage needs to be lowered. But do i need to change the VoltageCap settings?
Any advice gratefully received.
