    efficient bms with active balancing system using fliback tra

    to nubuo, paasive cell balancing use resistors to drop the extra charge from higher cells dissipate by heat with the resistors, many energy is lost on that process, flyback converters use the proper power from the batteri to power the lower cells . Nothing in power control means 100% of...
