Battery Management System (BMS)
Thanks to years of research and development your
OzCharge
®
Lithium battery has state of the art
technology monitoring the battery. Internally within your battery, an active Battery Management System
or BMS constantly monitors the individual cells for voltage, temperature, state of charge, cell balance,
discharge loads, charge voltage and charge current.
