I've got 2 lifepo4 160ah battery:
- one old (non smart)
- one new (with smart option
Both are managed with an external BMS ve.bus.
I don't want to put the battery in parallel because one is more than 3 year old and the other is brand new. So I decided to put a 3 way switch for choosing between the first or the second battery.
Can I monitor my state of charge of the both battery with a BMV 712 ?
I make a scheme for better understanding:
Is my wiring good ?
