5. Operating Instructions
5.1 Charging the Battery
Always use a dedicated LiFePO4 battery charger. The battery supports a wide operating temperature range for discharge (-4°F to 158°F / -20°C to 70°C). For charging, the temperature range is 32°F to 149°F (0°C to 65°C).
- Connect the LiFePO4 charger to the battery terminals (positive to positive, negative to negative).
- Plug the charger into a suitable power source.
- Monitor the charging process via the Bluetooth APP. The BMS will manage the charging parameters to prevent overcharge.
5.2 Discharging the Battery
The battery is designed for deep cycle applications and can be discharged to 100% Depth of Discharge (DOD). The intelligent BMS provides protection during discharge.
- Ensure your connected devices are within the battery's capacity limits.
- The battery's low-temperature cut-off protection will automatically stop discharge if the temperature drops below -4°F (-20°C) to prevent damage.

6. Maintenance
- Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean as necessary.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place.
- Cleaning: Use a dry cloth to wipe down the battery casing. Do not use harsh chemicals or abrasive cleaners.
- Firmware Updates: Check the HumsiENK Smart APP periodically for any available firmware updates for the battery's BMS.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging. | Incorrect charger type; loose connections; BMS protection activated. | Ensure a LiFePO4 compatible charger is used. Check all cable connections. If BMS protection is active (check APP), disconnect load/charger and allow battery to reset. |
| Battery not discharging/no power output. | Low temperature cut-off; overdischarge protection; short-circuit protection. | Check ambient temperature (must be above -4°F / -20°C). Check battery voltage via APP. Disconnect load and allow battery to reset if protection is active. |
| Bluetooth APP not connecting. | Out of range; Bluetooth off; APP issue. | Move closer to the battery (within 15m). Ensure Bluetooth is enabled on your device. Restart the APP or your device. |
