Volthium Green BIM Lithium Contactor 225 A

The Precision Circuits Lithium Battery Isolation Manager (Li-BIM), product code 00-10041-260, is a smart battery isolator designed for RVs, motorhomes, and fifth-wheels. It connects and charges both your house and engine batteries—charging the house battery while driving and the engine battery when plugged into shore power.

Optimized for lithium house batteries and lead-acid engine batteries, it prevents overcharging, reduces alternator strain, and supports manual override for emergency starts. Handles 225A continuous (not 160A as listed in the spec sheet).

Ideal when paired with the Precision Circuits Battery Guardian!
