The AIMS Power 12V 135Ah LiFePO4 Battery is a lithium iron phosphate battery designed for RVs, boats, commercial vehicles, golf carts, off-grid systems, battery backup power, and other properly sized 12V stored-power applications. This battery includes a built-in heater, wake-up button, Bluetooth monitoring, state-of-charge display, smart BMS protection, and RV-C/CAN communication support for compatible system integration. With 12.8V nominal voltage, 135Ah nominal capacity, and 1728 watt hours, it provides a compact lithium storage option for systems that require stable DC power delivery. The Group 31 format, dual-position mounting feet, IP65 rating, and removable carry handles support flexible installation planning. This battery is not intended for use as a starting battery and should be used with approved LiFePO4 charging equipment.
This AIMS Power lithium battery provides 135Ah capacity and 1728 watt hours for properly sized 12V power systems. Its LiFePO4 chemistry supports stable output voltage, long cycle performance, and a lighter footprint compared with many traditional lead-acid battery options.
The built-in heater supports charging in cold conditions when an external charger is connected, while the wake-up button helps reactivate the battery from sleep or low-voltage conditions. These features help simplify recovery and cold-weather charging support in compatible systems.
Bluetooth monitoring allows users to review battery status through the AIMSBATC app, including voltage, current, state of charge, cycles, temperature, and remaining capacity. The LFP12V135A model also includes RV-C/CAN communication support for compatible RV and power system integrations.
The integrated smart BMS supports cell balancing and protection against short circuit, overcharge, over-discharge, low and high temperature conditions, over-current, and high voltage. The IP65-rated design provides added splash and dust resistance for suitable installations.
This 12V 135Ah LiFePO4 battery is designed for stored-power applications where lithium performance, cold-weather charging support, Bluetooth visibility, and RV-C communication are important system considerations.
With dual-position mounting feet, removable carry handles, smart BMS protection, and a Group 31 format, the LFP12V135A supports properly designed RV, marine, commercial vehicle, and off-grid battery systems.
