LiFePO4 12V/12.8V 100Ah LiFePO4 Battery

12.8V 100Ah LiFePO4 Battery | LiFePO4 Technology | Long-Lasting Power & Fast Charging

Product Overview

Replace your heavy, maintenance-hungry lead-acid bank with the GreatVolt 12.8V 100Ah LiFePO4 battery, engineered for extended cycle life, enhanced safety, and reliable performance in demanding environments. With built-in low-temperature protection, this drop-in solution ensures uninterrupted power down to freezing temperatures—perfect for RVs, marine vessels, and solar energy systems.

12.8V 100Ah LiFePO4 Battery

Key Features

  • Low-Temperature Protection: Automatically suspends charge below 0 °C and resumes at safe thresholds to safeguard cell integrity.

  • 3,000+ Cycle Life: Delivers up to 10× the lifespan of conventional lead-acid batteries at 80% DoD.

  • High Discharge Rate: Supports continuous 100 A discharge (peak 200 A) for heavy-load applications.

  • Lightweight Design: At just 12 kg—over 60% lighter than a comparable lead-acid bank—improves handling and fuel economy.

  • Built-In BMS: Advanced Battery Management System provides over-charge, over-discharge, over-current, and short-circuit protection.

  • Fast Charging: Charge from 20%→100% in 4–5 hours using a compatible 12 V LiFePO4 charger.

  • Maintenance-Free: No watering, no equalizing—set it and forget it.

12.8V 100Ah LiFePO4 Battery2

Applications

  • RVs & Camper Vans: Power lights, appliances, water pumps, and HVAC—without the bulk or upkeep of lead-acid.

  • Marine & Boating: Ideal for trolling motors, navigation electronics, and deck lighting with stable voltage under load.

  • Solar & Off-Grid: Stack in series or parallel to build custom 12 V, 24 V, or higher-voltage banks for cabins and remote installations.

Installation & Use

  • Drop-In Replacement
    Our 12.8V 100Ah LiFePO4 battery shares the same footprint and mounting points as a standard 12V lead-acid, so you can swap it into your RV, boat, or solar cabinet with no modifications needed.

  • Plug-and-Play Terminals
    Fitted with color-coded M8 threaded studs, connection is foolproof—simply match positive to positive and negative to negative, tighten, and you’re ready to go.

  • Scalable Battery Banks
    The integrated BMS safely supports series (up to 4 × 12.8V for higher voltage) and parallel (up to 4 × 100Ah for greater capacity) configurations. Detailed wiring diagrams for 12V, 24V, 36V, and 48V setups are included.

  • Quick-Start Guide
    Arrives pre-charged to ~35%, ready for immediate installation. The step-by-step manual walks you through the first full charge, system integration (charger/inverter hookup), and best-practice maintenance.

  • Expert Technical Support
    Along with the printed installation guide, you get direct access to GreatVolt’s support team—via phone or email—to answer any questions and ensure a smooth, hassle-free setup.

FAQ

  • Inspect the carton and battery for any transit damage.

  • Fully charge the battery using a compatible 12 V LiFePO4 charger before initial use.

  • Verify voltage with a digital voltmeter to confirm a full charge (~14.6 V).

  • Use a charger with a LiFePO4 profile: constant-current until 14.6 V, then float at 14.6 V.

  • Maximum recommended charge current is 50 A; a 20 A charger will take ~5 hours from 20 %→100 %.

  • Do not charge below 0 °C—wait until the battery warms above freezing.

Yes. A LiFePO4-specific charger prevents over- or under-charging.
❌ Do not use standard lead-acid or AGM chargers, which can damage the cells.

  • None. LiFePO4 is a true “set-and-forget” chemistry—no watering, no equalizing cycles.

  • Periodically check terminal torque and clean corrosion with a non-conductive spray.

Rated for ≥2,000 cycles at 80 % depth-of-discharge—translating to 7–10 years in typical RV, marine, or solar service.

  • Discharge: –20 °C to +60 °C

  • Charge: 0 °C to +45 °C (charging is disabled below freezing to protect the cells)

  • Series: Up to 4× 12.8 V units for higher voltages (25.6 V, 38.4 V, 51.2 V).

  • Parallel: Up to 4× 100 Ah units for increased capacity.
    Always use batteries of identical age, capacity, and state-of-charge, and install a proper balancer or BMS.
