LiFeBlue Battery

12 Volt, 100AH

Model LB12100D

Lithium Iron Phosphate (LiFePO4)


The LB12100D is ideal for deep cycle energy storage in recreational vehicles (RV) and boats. In addition to RV and Marine use, it is well suited for all 12, 24, 36 or 48 Volt off-grid use, industrial applications and more.

Our "drop in" replacement battery is unlike any other on the market. The automatic BMS system offers 10 different protection modes including, over and under voltage, over and under temperature, over current, short circuit, fault events and more. We have specially designed the BMS for RV and Marine use where there are multiple charge sources with different charge profiles and voltages. Our battery can be charged directly from ANY PV solar controller, ANY inverter/charger and with properly sized wiring, ANY alternator can be used without the need for a special regulator or DC-DC converter. You do not need a special "Lithium" capable charger. Some multi-stage converters will not work but any standard CV converter that can output 13.8 Volts or higher will work.

Our New Design

This is our newest D model battery, Version 3, that has the latest battery cell development and our new BMS, designed with the future in mind. A dual Modbus data port allows us to update firmware should it become necessary or to add new features. Comminications development is ongoing now that will let you use Smart Connect WIFI App from anywhere you have an internet connection. With Push Notifications, you will be kept up to date about your battery condition and State of Charge (SoC). A top mounted reset button has been added to check the SoC or to reset the MCU should that need occur.

Smart Connect Bluetooth Monitoring

Every LiFeBlue Battery has Wireless Bluetooth communications built in. Our free Aple IOS or Android App called Smart Connect keeps you informed about the functioning of your battery from your tablet or smart phone. No internet connection is needed!

Our App includes Battery Monitoring so you will always know the State of Charge (SoC) or how much energy is left in the battery. This feature is not available in most other batteries and will save you hundreds of dollars buying an external battery monitor.

The Event page will list any fault event to help diagnose any problem you may have.
