12.8V 100Ah LiFePO4 Battery

Key Features

  • Bluetooth Smart Monitoring
    Track voltage, state-of-charge, temperature, and cycle count wirelessly via the GreatVolt mobile app.

  • Auto-Heating Function
    Built-in heater engages below 0 °C to safely enable charging down to 0 °C.

  • Extended Cycle Life
    ≥ 3,000 cycles at 80 % DoD—roughly 7–10 years of typical use.

  • High Discharge Capability
    100 A continuous (1C) and 200 A peak (2C for 30 s) to power heavy loads.

  • Advanced BMS Protection
    Safeguards against over-charge, over-discharge, over-current, short-circuit, and temperature extremes.

  • Lightweight & Compact
    At just 12 kg—over 60 % lighter than equivalent lead-acid banks—boosting efficiency and ease of installation.

  • Fast-Charge Support
    20 %→100 % in ~4–5 hours with a 20 A charger (up to 50 A max).

FAQ

  • Inspect for any transit damage.

  • Fully charge with a compatible 12 V LiFePO₄ charger (14.6 V float) before initial use.

  • Power on Bluetooth monitoring to confirm starting voltage, state-of-charge, and health status.

Bluetooth lets you view real-time battery parameters—voltage, state-of-charge, cell temperature, and cycle count—and receive low-voltage or temperature alerts directly on your device.

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

  • Maximum charge current is 50 A; at 20 A, a 20 %→100 % fill takes ~4–5 hours.

  • Do not charge below 0 °C—activate heating first (see Q 4).

heating function to allow charging under ambient temperature below 0°C/32°F, heating pad will be turned on automatically and heated up by the energy from charger when the sensor(s) detects the temp. over cells below 0°C/32°F, it turns off automatically when the temp. over the cells reach at 5°C/41°F.

  • Discharge: −20 °C to +70 °C

  • Charge: 0 °C to +50 °C (heating active below 0 °C; charging disabled until ≥0 °C)

Rated for ≥2,000 cycles at 80 % DoD—equivalent to 7–10 years of typical RV, marine, or solar use.

  • Series: Up to 4 × 12.8 V units (25.6 V, 38.4 V, 51.2 V systems)

  • Parallel: Up to 4 × 100 Ah units for increased capacity
    Always match capacity, age, and state-of-charge, and use a balancing BMS.

None—LiFePO₄ is truly maintenance-free. Simply inspect terminal torque occasionally and clean contacts if corrosion appears.
