The AIMS Power KIT-ISOREG Lithium Battery Regulator and Dual Battery Isolator Kit is designed for 12V alternator charging systems that need lithium battery voltage protection and automatic starter battery isolation. This kit pairs the LFP12V200AREG 200A lithium battery voltage regulator with the BATISO300 300A dual battery sensing isolator to help manage charging between a starting battery and auxiliary lithium battery bank. The regulator controls incoming DC charging voltage from alternators, wind, hydro, or other compatible 12V charging sources, while the isolator manages automatic connection and separation between the starting and auxiliary batteries. Together, the system supports work trucks, fleet vehicles, commercial food trucks, service vehicles, overland builds, and other high-demand mobile power applications. The kit is backed by a 3-year warranty and lifetime tech support.
The included LFP12V200AREG regulator continuously monitors incoming DC power from alternators up to 200A or other compatible 12V charging sources. It supplies power within the supported 9.4–14.4V range and disconnects output below 9.2V or above 14.6V to help protect lithium battery systems from unsafe voltage conditions.
The BATISO300 dual battery sensing isolator monitors both the starting battery and auxiliary battery. It automatically connects the batteries when voltage reaches 13.2V and disconnects below 12.7V to help protect the starter battery from auxiliary battery discharge.
This kit is built for demanding 12V mobile power layouts that may include high-output alternators, long drive cycles, large auxiliary lithium battery banks, and continuous electrical loads. It is a practical solution for commercial vehicles, work trucks, food trucks, RV lithium upgrades, fleet vehicles, and overland power systems.
The regulator manages charging safety by controlling voltage, while the isolator manages battery connection and separation. Used together, they provide a more complete approach to 12V lithium alternator charging than using either component alone.
This AIMS Power kit combines 200A lithium battery voltage regulation with 300A dual battery isolation for compatible 12V alternator charging and auxiliary battery systems.
Designed for work trucks, food trucks, RV lithium upgrades, fleet vehicles, and overland systems, KIT-ISOREG helps manage charging voltage while protecting starter battery separation.
