locked Re: Batteries starting to get weak - MMM - What to do -


Elja,   I am pretty sure ALL lifePo4 batteries have a built in BMS inside the casing. So each battery has one. You would NOT want one for a whole bank from what I understand. If that were to malfunction then you could lose the whole system rather than just one battery. The BMS is what regulates the charging and making sure all cells charge up evenly.
