The Victron Energy Battery Management System BMS 12/200 lets you safely connect any size 12V alternator (and start battery) to Victron LiFePO4 Smart Batteries. This all-in-one Battery Management System, Current Limiter, Battery Combiner and Battery Protector is a robust and compact solution, specifically designed for 12V systems with 12V alternators, such as vehicles and boats.
The BMS 12/200 monitors and protects each individual battery cell within the battery (or battery bank) and will disconnect the alternator, charge sources or DC loads in case of low battery voltage, high battery voltage or over temperature.
The dedicated alternator connection provides current limiting and one-way traffic from the alternator into the battery, this so any size alternator (and start battery) can be safely connected to the Smart Lithium battery or batteries and the starter battery is protected from excessive discharge.
The dedicated load connection will disconnect loads and charge in case of low battery voltage, high battery voltage or over temperature.
The BMS is also equipped with a remote on off connector, to turn the BMS (and the system) off via a remote switch.
