Integrated Protection Features
The built-in BMS provides safety monitoring for:
- Overcharge and Over-discharge
- Over-current and Short circuit
- Temperature protection
Dealer Maintenance & Storage Guidelines
- Storage Maintenance: Charge and discharge the battery pack once every 2 months to prevent over-discharge. Maintain voltage between 13.28V and 13.6V during storage.
- Installation: Install in a well-ventilated, dry, and clean environment. Ensure terminal polarities are correct to avoid fire or equipment damage. Do not exceed specified torque when fastening M8 terminals.
- Usage Tip: Shallow charging and discharging (discharging to 80% of nominal capacity) is recommended to improve overall cycle life. Ideally, recharge the battery pack within 12 hours of use to maximize service life.
