EXTRA DIGITAL LiFePO4 Battery 12.8V 20Ah Deep Cycle with BMS

Unlike conventional lead-acid batteries that fade after a few hundred cycles, this LiFePO4 battery delivers over 2000 deep cycles at 80% depth of discharge. It stores 256Wh of energy in a compact, maintenance-free ABS housing and weighs a fraction of an equivalent AGM or gel battery. The built-in Battery Management System protects against overcharge, over-discharge, overcurrent and short circuits, making it a safe, long-lasting power source for solar installations, RVs, marine electronics and backup systems.

Highlights

• Lithium Iron Phosphate (LiFePO4) chemistry for superior safety and thermal stability
• Nominal voltage 12.8V, capacity 20Ah, total energy 256Wh
• Integrated BMS with cell balancing and comprehensive protection
• Supports up to 4 batteries in series or parallel for flexible system design
• M5 threaded terminals for secure, low-resistance connections
• Wide operating temperature range: -20°C to 60°C (discharge)

In daily use

Connect the battery to your solar charge controller, inverter or DC load using the M5 terminals. The BMS automatically manages charging and discharging, so you can leave the system unattended without worry. With a maximum continuous discharge current of 20A (1C) and peak current of 40A for short bursts, it handles most 12V appliances, LED lighting, pumps and communication equipment. The low self-discharge rate of less than 3% per month means the battery retains its charge during storage, ready when you need it.
