The Rock Solid Series semi-solid battery must be stored and operated within strict temperature and electrical limits to preserve safety and cycle life. Exceeding these limits can result in capacity fade, degradation, or hazardous failure.
- Temperature storage constraint: Store the battery in a dry environment between -20°C and 65°C to prevent permanent capacity loss.
- Charge temperature limit: Only charge the battery when the ambient temperature is between 0°C and 45°C to avoid internal damage.
- Discharge cut-off voltage: Discharge must cease at 32.5 V to prevent over-discharge and irreversible cell degradation.
- Continuous discharge current limit: Exceeding 20 A (AFEABS4820) or 13 A (AFEABS4813) continuous discharge can cause thermal runaway.
Follow these steps to ensure safe charging and discharging of the semi-solid battery. Adherence to the specified current and temperature limits prevents damage and maintains cycle life.
Required Equipment: Standard e-bike battery charger
- Inspect the battery
Inspect the battery housing for cracks, swelling, or leakage before installation or use. - Verify operating temperature
Ensure the ambient temperature is within the discharge range of -20°C to 65°C before connecting the load. - Set charge parameters
Confirm the charger output voltage matches the nominal 48 V and limit charging to temperatures between 0°C and 45°C. - Monitor discharge current
Verify the continuous discharge current does not exceed 20 A for model AFEABS4820 or 13 A for model AFEABS4813. - Connect and disconnect safely
Connect the battery to the motor controller only when the system is powered off to avoid arcing.
How does the semi-solid electrolyte in the Rock Solid Series affect continuous discharge current capability compared to conventional liquid electrolyte e-bike batteries?
The semi-solid electrolyte enables a maximum continuous discharge of 20 A for the AFEABS4820 model and 13 A for the AFEABS4813 model, which is comparable to high-quality liquid electrolyte packs. The trade-off is that the semi-solid design provides enhanced thermal stability and leak-proof construction, reducing the risk of thermal runaway under sustained high-load conditions like hill-climbing, while maintaining a stable discharge temperature range from -20°C to +65°C.
Can the ATOMFAIR Rock Solid Series battery be integrated into existing e-bike frames designed for standard 48 V lithium-ion packs without modifying the battery management system?
Integration requires a compatible BMS with over-discharge, over-current, and cell balancing functions, as specified in the product notice. The AFEABS4820 measures 510 × 80 × 100 mm and the AFEABS4813 measures 230 × 95 × 75 mm, so physical fit depends on frame geometry. Both models use a 13S1P configuration at 48 V nominal, matching standard e-bike voltage, but the BMS must be verified to handle the respective 20 A or 13 A maximum continuous discharge.
What are the specific storage and preconditioning requirements for the Rock Solid Series semi-solid battery before first use to ensure cycle life exceeds 1200 cycles?
Pre-condition new batteries at room temperature before the first full cycle, as stated in the product notice. Store in industrial-grade moisture-proof packaging with anti-static shielding, avoiding extended exposure above 65°C. Charge only within the recommended voltage range (0°C to +45°C) and use a compatible BMS to prevent over-discharge below 32.5 V cut-off, ensuring the ≥1200 cycle life at 80% SOH.
The Rock Solid Series semi-solid battery delivers enhanced safety and thermal stability for e-bike applications, with a wide discharge temperature range and cycle life exceeding 1200 cycles, though charging is restricted to 0-45°C and prolonged high-temperature exposure should be avoided.
Positive
- Semi-solid electrolyte safety: Enhanced thermal stability, leak-proof construction, and superior safety compared to conventional liquid cells, with validated nail penetration and overcharge test passage.
- Long cycle life at 80% SOH: ≥1200 cycles retaining 80% capacity, providing durable performance for years of daily commuting and reducing replacement frequency.
Trade-offs
- Narrow charge temperature range: Charging is only permitted between 0°C and 45°C; charging below freezing is not supported, requiring temperature-controlled storage or pre-conditioning in cold climates.
- High-temperature exposure limit: Extended exposure to temperatures above 65°C must be avoided, as it may degrade performance and compromise safety, necessitating thermal management in hot environments.
