BM500 Pro battery shunt

Measures battery voltage, current, state of charge and runtime for 12V to 48V lithium and lead-acid banks, up to 600A.

Part of the LIBERGRID system

TBB’s M Series batteries have their own shunt built in. For any other battery bank, the BM500 Pro measures what goes in and out, so the LIBER43 can show an accurate state of charge and time remaining.

Features

Gives a LIBERGRID system an accurate state of charge with batteries other than TBB’s M Series.
Monitors the house battery plus two starter batteries.
Programmable outputs can control external devices.
Suits RVs, boats and utility vehicles.
