Unleash heavy-duty, long-lasting power with the CELLWATT™ 12V 20Ah Lithium Iron Battery Pack. Specially engineered for high-drain applications and deep-cycle performance, this high-capacity powerhouse is the ultimate modern upgrade to replace heavy, inefficient 12V 20Ah lead-acid (SLA) batteries. Whether you are running agricultural equipment, solar systems, or demanding backup setups, CELLWATT™ delivers consistent, rock-solid energy every single time.
Military-Grade Safety with Smart Built-in BMS
When handling high-capacity power, safety is everything. The CELLWATT™ 20Ah pack features a heavy-duty, integrated Battery Management System (BMS) that acts as an intelligent internal shield. It monitors every single cell in real-time to offer automatic protection against:
- Over-charging and deep, damaging over-discharging
- High-current surges and dead short circuits
- Thermal overloads and uneven cell balancing
This advanced engineering allows the pack to comfortably smash through 2,000 to 3,000+ complete charge-discharge cycles while retaining peak efficiency. It outlasts traditional batteries by nearly a decade!
Maximum Performance, Minimal Weight
Why haul around heavy lead plates? The CELLWATT™ 20Ah pack gives you double the usable energy at less than half the weight of a standard SLA battery. Thanks to its flat voltage discharge curve, it delivers 100% of its rated capacity with steady, unwavering voltage. Your devices won’t slow down or fade, even when the battery is running low.
