A complete explanation on how to initially "Bottom Balance" Lithium Iron Phosphate battery cells. No need for an expensive (and possibly dangerous) BMS. I will show you how to accomplished this with 100aH Calb CA series (grey) cells. This was done prior to ever putting them into full-time usage. Two plus years later, several blackouts around us (Those on Grid power had blackouts, not us on Solar) and nothing to write home about. The battery bank just performs. No noticeable cell drifting whatsoever. Learn how to wire up your off grid battery bank. Series? Parallel? C ratings? huh?
