12.8V 300Ah Lithium Battery – High Capacity for Long-Term Off-Grid Power

This 12.8V 300Ah lithium iron phosphate (LiFePO₄) battery is designed for users seeking long-lasting energy storage and stable performance. With a usable capacity of up to 300Ah (over 3.84 kWh) and dimensions of 522 × 240 × 221 mm, it's ideal for RVs, marine applications, solar backup systems, mobile food trucks, and off-grid cabins.

Long-Lasting Off-Grid Power

The high capacity provides stable, long-lasting power for demanding applications. Ensuring extended runtime, it's ideal for long-distance travel, remote installations, and continuous operation without frequent recharging. It's ideal for large off-grid systems, marine operations, and commercial or industrial installations where reliability and durability are critical.

Durable ABS Housing

The high-strength ABS housing is lightweight, impact-resistant, and corrosion-resistant, making it ideal for indoor and outdoor installations. Its flame-retardant properties and rugged sealed design enhance safety and reliability, while its compact size allows for flexible installation in tight spaces.

Smart BMS with Bluetooth Monitoring

Equipped with automotive-grade BMS technology, this battery allows real-time battery monitoring via a Bluetooth app. You can view voltage, current, state of charge, temperature, and cycle count directly from your smartphone, making it ideal for outdoor enthusiasts, sailors, or technicians requiring on-the-go diagnostics.

An Ideal Lead-Acid Battery Replacement

Compared to AGM or GEL batteries, this lithium iron phosphate battery is 50% lighter, charges four times faster, and boasts over 3,000 cycles at 80% depth of discharge. It's maintenance-free, has no memory effect, and can be installed in any orientation, making it a true lead-acid battery alternative.
