The AIMS Power LFP12V200AREG Lithium Battery Voltage Regulator is engineered for 12V DC systems that charge lithium batteries from an alternator or other compatible DC charging source. Using solid-state technology, this 200 amp regulator monitors input voltage and disconnects output when voltage moves outside the supported operating range. It helps protect lithium battery banks from overcharging, unsafe voltage conditions, and charging-source spikes in demanding vehicle and mobile power applications. This model is designed for 200A alternator or DC device applications, with a 100A version available separately for smaller systems. It is backed by a 3-year warranty and lifetime tech support.
This AIMS Power voltage regulator is built for 12V lithium battery systems charged from alternators, wind, hydro, or other compatible DC sources. It is especially useful in work trucks, commercial food trucks, fleet vehicles, service vehicles, RV lithium upgrades, overland builds, and systems using high-output alternators with large lithium battery banks.
The regulator supplies power within the 9.4–14.4V DC operating range and disconnects output below 9.2V DC or above 14.6V DC. Once voltage returns to the supported range, the unit automatically resets after a 2-minute delay and resumes normal operation.
The LFP12V200AREG supports continuous-duty charging applications where high-output alternators, large lithium battery banks, and long drive cycles can place extra demand on the system. Its low-voltage, high-voltage, and over-current shutdown behavior helps add a layer of protection during demanding charge cycles.
The unit is designed for 12V battery systems and common 2-wire DC applications. Follow AIMS Power installation guidance carefully, including port labeling and system layout, before connecting the regulator into any alternator, battery, wind, hydro, or DC charging setup.

This AIMS Power 200A lithium battery voltage regulator helps manage 12V alternator charging for compatible lithium battery systems in commercial vehicles, RVs, work trucks, and mobile power builds.
With solid-state operation, low and high voltage protection, over-current shutdown behavior, and automatic reset, the LFP12V200AREG supports safer charging control for demanding 12V DC applications.
