5. Operating Instructions
5.1 Charging the Battery
Use the provided Redodo 14.6V 40A LiFePO4 charger. Connect the charger to the battery, then plug the charger into a standard AC outlet. The charger's pre-charge mode can reactivate a battery that has been discharged to 0V. Charging times vary based on battery capacity:

Figure 5: Reference charging times for various battery capacities using the 14.6V 40A charger. For example, a 100Ah battery takes approximately 2.5 hours, and a 200Ah battery takes about 5 hours.
Other recommended charging methods include:
- 12V (14.6V) 20Amp LiFePO4 Battery Charger (approx. 5 hours for 100Ah)
- Solar Panels (400W+ MPPT, within one sunny day)
- Generator (20A AC-DC Charger, approx. 5 hours for 100Ah)
- Alternator (20A DC-DC Charger, approx. 5 hours for 100Ah)

5.2 Discharging
The battery is designed for deep cycle applications and can be discharged to 100% Depth of Discharge (DOD). The 100A BMS protects against over-discharging. Ensure your load does not exceed the battery's continuous discharge current rating.
5.3 Parallel and Series Connections
For increased capacity or voltage, multiple Redodo LiFePO4 batteries can be connected in parallel or series. Refer to the specific guidelines for parallel/series connections to ensure proper balancing and safe operation. It is recommended to use batteries of the same model and state of charge for optimal performance.
6. Maintenance
- Regular Inspection: Periodically check 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. Avoid extreme temperatures.
- Cleaning: Keep the battery and charger clean and free from dust and debris. Use a dry cloth for cleaning.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Loose connections, faulty charger, battery deeply discharged (0V) | Check all connections. Ensure charger is functioning. Use the charger's pre-charge mode to attempt reactivation of a 0V battery. |
| Low power output | Battery not fully charged, excessive load, internal BMS protection activated | Fully charge the battery. Reduce the load. Disconnect and reconnect the battery to reset BMS if necessary. |
| Charger indicator light not on | No AC power, charger faulty, incorrect connection to battery | Check AC power source. Verify charger connections to battery. Contact support if charger is faulty. |
