I have installed a BMV-712 on my 2023 EZGO Golf Cart - which has factory lithium batteries - two packs - each pack is 54.66ah. So I have a total of 110ah.
However - when the golf cart is parked and the key is turned to off - the system cuts the power coming from the main power terminals - thus cutting the power to the BMV.
Once the cart is powered back on - the voltage reading is correct - however the system synchronizes and assumes the batteries are back to 100%.
1. - is it ok for the BMV-712 to have the power cut off like this every time the golf cart is turned off?
2. - is there any other way for the BMV-712 to "remember" the last state of charge when power was cut off? When the cart is charging - the main terminals are turned back on so the BMV-712 does see "charge" coming to the batteries.
