2. Each cell shall be used under strict monitoring, control, and protection by the BMS.
3. Before the first use, always charge the cells to full voltage. | FAQ: LiFePO4 battery charging guide.
4. We will match (capacity, voltage, resistance) all cells before delivery.
5. The battery is suitable for DIY lovers with experience.
📢 NOTICE BEFORE USING
🟢DO: Pre-install Check! Ensure a thorough pre-installation examination.
1. Check the overall physical of each cell and avoid missing accessories.
Visually inspect cells for any damage, swelling, leaks, etc. Do not use any cells that look physically damaged.
2. Test cell voltage.
Each cell should be between 2.5-3.56V when stored at open circuit. Significantly higher or lower voltages may indicate a problem.
3. Test capacity.
Test capacity on each cell individually using a battery analyzer or specialized tester. Discharge to 2.5V at 0.5C. Capacity should be close to rated spec.
4. Connect to use.
Please balance the cells before assembly. Match cells for performance. Group cells with similar tested capacities together in the pack. Don’t mix weak and strong cells. Recommend the average voltage of each cell by less than ±0,1V.
• Never discharge cells immediately following delivery.
• Do not mix cells from various manufacturing series, even if they are of the same type and capacity, and do not install such cells together. Always use cells from the same manufacturing series and delivery batch for every battery.
I guarantee you’ll be happy with cells you purchase from us. When your cells arrive if you’re not completely satisfied please contact us at [email protected] to help solve the problem.
