The ROCKSOLAR 12V 10Ah is a small deep-cycle lithium iron phosphate battery with a built-in BMS, rated for at least 2,000 cycles at 100% depth of discharge. It stores about 128 Wh nominal, roughly 122 Wh usable by ROCKSOLAR's estimate, and weighs about 1.2 kg. That makes it a compact, long-lived alternative to a sealed lead-acid block of similar size, which typically lasts a few hundred cycles and weighs several times more. It suits light, low-draw jobs rather than powering an inverter or a trolling motor.

This is a rechargeable 12V deep cycle battery that uses lithium iron phosphate (LiFePO4) chemistry. It has a built-in battery management system (BMS). Nominal voltage is 12.8 V and nominal capacity is 10 Ah.
Nominal energy is 128 Wh (0.128 kWh), based on 12.8 V × 10 Ah. Estimated usable energy is 121.6 Wh (0.1216 kWh), calculated at 95% of nominal energy. This is an estimate, not a rated usable capacity. Actual delivered energy depends on operating conditions and any conversion losses.
For solar charging, use a compatible solar charge controller set to this battery's charging voltage and current limits. Do not connect an unregulated solar panel directly to the battery. Charge only within the specified 0°C to 45°C range.
