I've had four EG4 48V batteries for a year and a half. most the time my EG4 3k inverters are set to USER, which I believe takes the BMS out of the equation. When the BMS is on, they take twice as long to charge and they will only discharge to 20%. I let them discharge to 10%, of course, now that it is cold weather, the warning lights are flashing every morning. SS says that I am harming the batteries, are they right or wrong?
