Description:
Experience the ultimate in energy storage with the POWERPITTAR® LK12.8-300 LiFePO4 battery. This high-performance SLA replacement lithium battery is engineered to be the perfect upgrade over traditional sealed lead-acid batteries in demanding 12V systems. It is a 100% drop-in replacement, meaning it fits into the same space and uses the same chargers with minimal configuration.
By switching to the LK12.8-300, you gain exceptional advantages: a dramatic weight reduction of approximately 60%, a doubled power output, and an unparalleled cycle life exceeding 4000 cycles at 100% Depth of Discharge (DOD) with a 1C rate. The advanced internal Smart Battery Management System (BMS) ensures safety against overcharging, over-discharging, over-current, and short circuits, while the stable LiFePO4 chemistry eliminates any risk of explosion or combustion. Its modular design also allows flexible configuration, supporting up to 4 batteries in series and up to 10 in parallel to meet your specific voltage and capacity requirements.
Applications:
- Solar / Wind Energy Storage Systems (Off-Grid & On-Grid)
- UPS (Uninterruptible Power Supply) and Backup Power
- Electric Vehicles (EV) and Electric Mobility
- Telecommunication Base Stations
- Medical Equipment
- Lighting Systems (Solar Street Lights, etc.)
- Marine and RV (Recreational Vehicle) Applications
