The AIMS Power LFP12V135A is a 12V 135Ah lithium iron phosphate (LiFePO4) deep cycle battery engineered for demanding power applications including RVs, marine, golf carts, off-grid systems, and commercial vehicles. With a nominal voltage of 12.8V and a rated capacity of 135Ah (minimum 125Ah at 0.5C, 77°F), this battery delivers consistent, stable output voltage that maximizes the efficiency of connected loads.
Unlike traditional lead-acid, AGM, or Gel batteries, the LFP12V135A offers superior cycle life of over 4,800 charge/discharge cycles (at 1C, 77°F, 80% DOD)—up to 8 times longer than conventional battery technologies. It is a direct drop-in replacement for most 12V lead-acid battery applications and fits the same footprint while weighing significantly less.
Key Features:
- Built-In Internal Heater: Automatically activates below 50°F (10°C), drawing up to 10A of charge current to warm the cells—enabling safe and efficient charging in cold climates without any external wiring
- Battery Wake-Up Function: A dedicated button allows recovery from over-discharge or low-voltage shutdown without needing a special charger or a parallel battery to revive it
- Bluetooth Monitoring: Pairs with the free AIMSBATC app (Android & Apple) to monitor state of charge, remaining capacity, temperature, full charge capacity, and more in real time
- Rotatable Digital Display: On-board LCD can be oriented in multiple positions for easy reading in any installation—exclusive to the LFP12V135A model
- Dual-Position Mounting Feet: Flexible mounting hardware included for versatile installation configurations
- RV-C Communication: Integrates directly with modern RV systems for seamless monitoring and control
- Advanced BMS Protection: Intelligent Battery Management System guards against overcharge, over-discharge, over-current, and short circuit; includes thermal safety fusing, cell balancing, CID, and automatic fault recovery
- Individual Cell Fusing: Each cell is independently fused—if a cell fails, it is automatically isolated to prevent further damage while keeping the battery operational
- Maintenance Free: No watering, equalization, or off-gassing—sealed and spill-proof in any orientation
- Sleep Mode: Automatically enters low-power sleep after 24 hours of inactivity to preserve charge
