What it is, and what it is for
ROCKSOLAR 12V 200Ah 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-T12200B, non-heated version. No built-in heater or self-heating function.
Discharge Current: 200A continuous; 600A peak for 3 seconds. The peak rating is short-duration only and must not be treated as a continuous discharge rating.
Discharge Cut-off Voltage: 10V, as stated in the user manual. Follow the manufacturer’s discharge limits and use compatible system protection settings.
Consistent Power Supply: Delivers steady energy output using flat voltage curve technology.
Superior BMS: Integrated system for protection against temperature changes, over-discharge, over-charge, and short circuits.
Discharge Temperature: Operates effectively between -20°C to 60°C, suitable for challenging environments.
Charging Temperature: Charge only within 0°C to 45°C. This non-heated model has no built-in heater. Do not charge below 0°C or rely on the BMS as a substitute for following the permitted charging range.
Enhanced Safety: Features cell balancing and over-current protection for longevity.
Global Standards: Compliant with UN38, IEC62133, and ISO 9001:2015.
10-Year Warranty: Demonstrates robust construction and reliability.
Multipurpose Usage: Ideal for marine, solar systems, RVs, and other large-scale power requirements.
Charging Specifications (User Manual)
- Charge voltage: 14.4–14.6V.
- Float voltage: 13.6–13.8V.
- Standard charging current: 40A.
- Maximum charging current: 100A.
- Charging temperature: 0–45°C. This non-heated model has no built-in heater; do not charge below 0°C.
Weight and Dimensions (User Manual)
- Battery weight: Approximately 23 kg (50.7 lb).
- Dimensions (L × W × H): Approximately 485 × 172 × 231 mm (19.09 × 6.77 × 9.09 inches).
Nominal and Estimated Usable Battery Energy
Nominal battery energy: 2.56 kWh. Estimated usable battery energy: 2.432 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.
