About this product

What it is, and what it is for

2 x ROCKSOLAR 12V 100Ah Deep Cycle LiFePO4 Batteries with BMS:

  • Two 12V-class (12.8V nominal) 100Ah batteries for a 24V system: 25.6V nominal, 100Ah, 2560Wh total when connected in series. Follow the battery manufacturer's installation instructions.
  • 6000+ service cycles, as listed for the ROCKSOLAR 12V 100Ah battery
  • Steady power: Flat voltage curve for consistent power output, no significant drop like traditional SLA batteries
  • Utilizes advanced LiFePO4 Battery Technology for dependable deep cycling
  • Smart Battery Management System for safety and longevity
  • Battery weight: 27 lb each; 54 lb for the pair
  • Suitable for harsh environments: Built-in BMS provides protection against temperature fluctuations, short circuits, over-discharge, over-current, and overcharge, and ensures battery cell balancing.
  • Operating temperature range for charging: 0°C to 45°C, discharging: -20°C to 60°C. BMS auto-shuts off the battery outside the working temperature.
  • Warranty: 10-year warranty and 10+ year service life

    Common questions

    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.
