Isolator & Lithium Battery Regulator Kit Designed For Alternator Charging

Lithium Battery Regulator with Dual Sensing Battery Isolator – 12V

Industrial Grade 12V lithium charging and battery protection system for commercial vehicles, fleet installations, and high demand mobile power applications.

This 12V lithium battery regulator and dual battery isolator kit safely manages alternator charging while automatically protecting and separating starting and auxiliary batteries for reliable daily operation.

How the System Works

Safe Voltage Control – Lithium Battery Regulator (LFP12V200AREG)

The regulator continuously monitors incoming DC power from alternators up to 200 amps, wind, hydro, or other 12V charging sources.

Voltage Protection Functions

• Operating range: 9.4V – 14.4V
• Disconnects battery from alternator if output below 9.2V or above 14.6V
• Automatically reconnects when voltage stabilizes
• Prevents overcharging from high-output alternators
• No time-limited charging restrictions, ideal for large battery banks
• Protects lithium and mixed battery chemistries
• Protects LiFePO4 lithium batteries from voltage spikes and charging surges

Unlike basic charging systems, the regulator controls voltage continuously, preventing damage caused by modern high-amperage alternators during extended operation.

This protection is critical for commercial vehicles running long shifts where sustained alternator charging can stress lithium battery systems.

Intelligent Charging & Isolation — Dual Battery Sensing Isolator (BATISO300)

The dual battery sensing isolator automatically manages power flow between the starting battery and auxiliary lithium battery.

Automatic Battery Management

• Connects batteries automatically at 13.2V
• Disconnects batteries below 12.7V
• Protects starter battery from deep discharge if the secondary battery is heavily or continuously discharged
• Allows charging from alternator, solar, or external chargers
• No ignition wire or manual switching required

In work trucks, service vehicles, and food trucks running refrigeration, lighting, or inverters continuously, automatic isolation ensures the vehicle always retains starting power.

Why the Regulator and Isolator Work Better Together

Using only a regulator or only an isolator leaves gaps in system protection.

Combined, this kit creates a complete dual battery charging system

• Alternator over-voltage protection
• Low voltage disconnect protection
• Automatic starter battery isolation
• Safe charging for large lithium auxiliary battery banks
• Protection for sensitive 12V electronics and inverter loads
• Fully automatic, hands-off operation

The regulator manages charging safety.
The isolator manages battery connection and separation.

Together, they form a commercial grade 12V power management solution.

Built for Long Shifts & Continuous Operation

Designed for demanding mobile power environments

• Commercial work trucks
• Fleet vehicles
• Food trucks
• Emergency and service vehicles
• Overland and mobile power systems

Handles

• High-output alternators
• Continuous electrical loads
