The ATOMFAIR semi-solid battery series requires strict temperature control during storage and operation to prevent thermal runaway. Use only with a compatible BMS that enforces over-discharge, over-current, and cell balancing protection.
- Thermal Exposure Limits: Never expose the battery to temperatures exceeding 65°C to prevent electrolyte degradation and thermal runaway.
- BMS Compatibility: Always connect the battery to a compatible BMS with over-discharge, over-current, and cell balancing functions.
- Charge Voltage Compliance: Charge the battery strictly within the manufacturer-recommended voltage range as per the datasheet.
- Pre-Conditioning Procedure: Pre-condition a new battery at room temperature before its first full charge-discharge cycle.
- Mechanical Protection: Protect the battery from physical impact, puncture, or compression to avoid internal short circuits.
Follow these steps to safely handle and initialize the ATOMFAIR semi-solid battery for first use. Proper preconditioning and BMS configuration ensure long cycle life and safe operation.
Required Equipment: Compatible battery management system (BMS), Manufacturer-approved charger
- Inspect Battery
Inspect the battery casing for cracks, swelling, or leakage before initial use. - Connect BMS
Connect a compatible BMS that enforces over-discharge, over-current, and cell balancing limits. - Verify Charger
Confirm the charger output voltage aligns with the battery's specified charge voltage range. - Precondition Battery
Allow the battery to equilibrate at room temperature for at least two hours before the first charge. - Initiate First Charge
Initiate the first charge cycle at a current not exceeding 0.5C rate while monitoring temperature. - Condition Cells
After full charge, perform an initial discharge cycle at 0.2C rate to condition the electrolyte. - Store Safely
Store the battery in a cool, dry environment between 0°C and 45°C to preserve cycle life.
How does the capacity selection between 20 Ah and 13 Ah models affect discharge current and physical integration for e-bike applications?
The 20 Ah model (AFEABS4820) supports a max continuous discharge of 20 A, while the 13 Ah model (AFEABS4813) supports 13 A, directly correlating with power delivery for hill-climbing and acceleration. The 20 Ah variant has larger dimensions (510×80×100 mm) versus the 13 Ah variant (230×95×75 mm), requiring more frame space. Both share 48 V nominal voltage, 13S1P configuration, and ≥1200 cycles to 80% SOH, making capacity selection a trade-off between peak current and physical footprint.
What BMS integration requirements and charge/discharge temperature constraints must be met for the ATOMFAIR Rock Solid semi-solid battery?
The battery requires a compatible BMS with over-discharge, over-current, and cell balancing protection. Charge temperature range is strictly 0 to +45°C, while discharge temperature range is -20 to +65°C. The discharge cut-off voltage is 32.5 V, and the 13S1P configuration must be respected. Pre-condition new batteries at room temperature before first full cycle to ensure proper activation.
What safety testing and storage precautions apply to the ATOMFAIR semi-solid electrolyte e-bike battery series?
The semi-solid electrolyte provides enhanced thermal stability, leak-proof construction, and passes nail penetration and overcharge tests for superior safety. Avoid prolonged exposure above 65°C. Packaging includes industrial-grade moisture-proof cartons with foam inserts, individual cell compartments, and anti-static shielding. For storage, pre-condition at room temperature before first cycle and always use a compatible BMS.
The Rock Solid Series semi-solid state battery for e-bikes delivers enhanced thermal stability and leak-proof construction via semi-solid electrolyte, with two capacity variants (20 Ah and 13 Ah) both rated for -20°C to +65°C discharge and ≥1200 cycles to 80% SOH, though charge is restricted to 0–45°C and a compatible BMS is mandatory.
Positive
- Semi-solid electrolyte safety: Enhanced thermal stability and leak-proof construction provide superior safety over conventional liquid cells, with verified nail penetration and overcharge test compliance.
- Wide temperature discharge range: Reliable discharge from -20°C to +65°C enables all-season e-bike operation, while ≥1200 cycles to 80% SOH supports years of daily commuting.
Trade-offs
- Restricted charge temperature window: Charging is only permitted between 0°C and +45°C; charging outside this range may cause performance degradation or safety issues.
- Mandatory BMS and preconditioning: A compatible BMS with over-discharge, over-current, and cell balancing is required, and new batteries must be preconditioned at room temperature before first full cycle.
