The battery cells in the Smart Lithium batteries are protected against over-charge, under-charge, charging at too low temperatures as well as charging at too high temperatures.
As part of the protection the battery has an integrated Balancing, Temperature and Voltage control system, the BTV. The BTV connects to an external Battery Management System, the BMS.
In case of multiple batteries, the BTVs of several batteries are daisy chained and then connected to the BMS.
You will need a Victron VE.Bus BMS or a Victron smallBMS to use this battery.
