What it is, and what it is for
ROCKSOLAR 12V 100Ah Deep Cycle LiFePO4 Battery
Cycle Life: Rated for at least 6,000 cycles under the manufacturer's test conditions: 25 ± 2°C, normal charging and 0.2C discharge at 80% depth of discharge, until capacity falls to 80% of its initial value. Actual cycle life varies with temperature, load and operating conditions. This cycle-test depth of discharge is separate from the estimated usable-energy planning figure below.
Model: R-T12100B.
Peak Discharge Current: 300A for 3 seconds. This is a short-duration peak rating, not a continuous discharge rating.
Discharge Current: Maximum 150A at 25°C; recommended 100A. The 300A peak rating applies for 3 seconds only.
Dimensions (W × D × H): 308 × 168 × 211 mm, ±2 mm per dimension (approximately 12.13 × 6.61 × 8.31 inches).
Weight: Approximately 12 kg (26.5 lb), without accessories.
Consistent Output: Delivers unwavering energy till the last drop with flat voltage curve technology.
Advanced BMS: Patented system provides comprehensive protection against temperature variations and circuit issues.
Operational Resilience: Efficiently handles diverse conditions, operating between -20°C to 60°C.
Optimal Charging: Auto shut-off outside working range, charging effectively from 0°C to 45°C.
Charging Specifications
- Charge voltage: 14.2V.
- Float voltage: 13.8V.
- Recommended charge current: 50A.
- Maximum charge current: 100A at 25°C.
Use a compatible LiFePO4 charger or solar charge controller configured to the manufacturer specifications. The maximum current is a limit, not the recommended everyday charging setting.
Protection: Includes cell balancing and over-current safeguards for enhanced safety and longevity.
Global Standards: Adheres to UN38, IEC62133, and ISO 9001:2015 certifications, ensuring international compliance.
10-Year Warranty: Comes with a trustworthy 10-year warranty, highlighting its robust build and dependability.
Versatility: Ideal for marine, solar power systems, RVs, and other high-capacity energy needs.
Nominal and Estimated Usable Battery Energy
Nominal battery energy: 1.28 kWh. Estimated usable battery energy: 1.216 kWh (95% of nominal). No separate usable-energy rating is stated in the linked ROCKSOLAR battery specification, so this is a planning estimate, not a manufacturer-tested usable-energy guarantee. Actual available energy varies with temperature, load, battery age, BMS limits and system settings. AC energy is lower after inverter losses. Always follow manufacturer charging and discharge limits.

Before you order.
If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.
What if I'm not sure this is the right product?
Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
