300AH 12V LiFePO4 series connection capable battery

Crafted out of Lithium Iron Phosphate (LiFePO4) technology, this 300AH 12V LiFePO4 series connection capable battery built to last. With 2,000+ recharge cycles (and up to 7,000 under ideal charging conditions) the 300 Ah provides 5 X the lifespan than your typical SLA battery– providing exceptional lifetime value. 300 Amp hours of capacity provides a full day of power for high amp draw trolling motors or for long days on the open road in your RV. Combine 2 for 24 Volts or 4 for a 48 Volt system. ideal for industrial purposes where you need a long lifespan battery that charges quickly, or for outdoor uses like trolling motors, solar energy storage, or boating.

Best Battery IP65 Waterproof Box

These ip65 waterproof battery box are made from hard plastics that ensure better durability and are strong enough to protect items kept inside them.

300AH 12V Series Battery Longer-lasting, MoreLlightweight And Safer Than Lead-acid Batterie

300AH 12V LiFePO4 series batteries are lighter, take less space and last longer. While the up-front cost is higher than Gel, AGM or Lead-Acid the overall cost of ownership is lower over time because they require no maintenance and they have up to 10x longer life.

Battery Management Systems – BMS

All kEHENG Batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, safe handling – and high-accuracy State of Charge (SOC) calculations.

300AH 12V LiFePO4 Series Battery USE Grade A Cell

Brand new Grade A+ Cell. Premium “CALB Quality”; Factory test and data report available based on QR code & Serial Number upon request.

Batteries In Series And Parallel

The main difference in wiring batteries in series vs. parallel is the impact on the output voltage and the capacity of the battery system. Batteries wired in series will have their voltages added together. Batteries wired in parallel will have their capacities (measured in amp-hours) added together.

Applications

Solar/wind Energy storage system
Golf carts
Recreational Vehicles(RVs)
Marine machine
UPS Backup power system
Solar street light

The 300AH 12V LiFePO4 series connection capable battery offers high, reliable performance in any climate or condition for RVs, campers, sailboats and battery-based solar systems.
