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



Each LifePo4 battery has some type of BMS. Most are internal. IT manages the charge and draw down for each of the cells inside it. Prevents overcharging, prevents draining the battery, and makes sure the cells are evenly charging and discharging among other things. ALL BMS's are not equal. There are quality issues with many on the market.
