4. Setup and Installation
Unpacking:
Carefully remove the battery from its packaging. Inspect the battery for any signs of damage. If damage is found, contact customer support immediately.
Initial Charging:
It is recommended to fully charge the battery before its first use. Use a compatible LiFePO4 charger (14.6V 75A recommended) or a solar panel system with an MPPT controller (recommended >400W).

Connecting the Battery:
- Ensure all connected devices are turned off before making connections.
- Connect the positive (+) terminal of the battery to the positive terminal of your load/charger.
- Connect the negative (-) terminal of the battery to the negative terminal of your load/charger.
- Ensure all connections are secure and tight to prevent arcing or poor contact.
Capacity Expansion (Series and Parallel Connections):
The E-LekTech 12V 600Ah LiFePO4 battery supports expansion up to 6 units in series and 6 units in parallel. This allows for greater capacity and higher voltage configurations.
- Series Connection: Connect batteries in series to increase the total voltage. For example, two 12V batteries in series create a 24V system.
- Parallel Connection: Connect batteries in parallel to increase the total capacity (Ah) while maintaining the same voltage. For example, two 12V 600Ah batteries in parallel create a 12V 1200Ah system.
Important Note for Series/Parallel Connections:
- All batteries used in a series or parallel bank must be of the same voltage and capacity.
- It is highly recommended to use batteries purchased at approximately the same time (within one month) to ensure optimal performance and balance.
- Before connecting batteries in series or parallel, ensure each battery is fully charged separately to achieve a voltage balance state.

6. Maintenance
LiFePO4 batteries require minimal maintenance compared to other battery types. Follow these guidelines to ensure optimal performance and lifespan:
- Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean terminals with a wire brush if necessary and ensure they are tightened securely.
- Cleaning: Keep the battery surface clean and dry. Use a damp cloth to wipe away dust or dirt. Do not use harsh chemicals or abrasive cleaners.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% of its capacity. Store in a cool, dry place away from direct sunlight and extreme temperatures. Recharge every 3-6 months to prevent deep discharge.
- Temperature: Operate and store the battery within its specified temperature range to maximize performance and lifespan. The BMS includes low and high temperature cutoff protections.
7. Troubleshooting
If you encounter issues with your E-LekTech battery, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Loose connections, incompatible charger, BMS protection activated (over-voltage, low temperature) | Check all cable connections. Ensure charger is LiFePO4 compatible. Verify ambient temperature is within charging range. |
| No power output | Battery discharged, BMS protection activated (over-discharge, over current, short circuit), loose connections | Check battery state of charge via app. Inspect connections. Reduce load if over current protection is active. |
| Battery overheating | Excessive load, poor ventilation, high ambient temperature | Reduce load. Ensure adequate ventilation around the battery. Move battery to a cooler environment if possible. BMS will activate overheating protection. |
| Inaccurate State of Charge (SOC) reading | BMS calibration needed, initial use fluctuations | Perform a full charge and discharge cycle to allow the BMS to recalibrate. Ensure the battery is fully charged periodically. |
If the problem persists after attempting these solutions, please contact E-LekTech customer support for further assistance.
