Hi
I am designing a system with x2 lifepo4 138ah 'powerwalls' which I bought without BMS. I am going to keep a close eye on the state of cell balance of the lifepo4's through a separate Battery Capacity Meter plugged into the 4s and balance charge them as necessary.
My system comprises the following - 300w panels, 100/20 victron smart solar mppt, victron multiplus 800/35 inverter charger, 712 battery meter, sterling B2B charger and victron battery protect.
I found the following schematic from a fellow member which Im thinking to use its pretty much the same as my own.
My question is will x1 battery protect be ok (keeping an eye on the discharge) and if so where is the best place to place it? Directly from the battery?
Im a complete newby and if this schematic is good I would use it.
Many thanks for all your help!
