📢 NOTE BEFORE PURCHASE
1. One Cell will come with one set busbar, bolt, and washer for free. (e.g. 4 Cells will come with 4 pcs(busbars + bolts + washers) .
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.
📢 NOTE BEFORE USING
🟢DO: Pre-install Check! Ensure a thorough pre-installation examination.
• Check the overall physical of each cell and avoid missing accessories. Visually inspect cells for any damage, swelling, leaking, etc. Do not use the cell if the cell casing has been pierced, leaked, broken, cracked, or otherwise visibly damaged.
• Cleaning of the terminals, bus bars, and wire terminal lugs. Ensure cables and terminals are kept clean and free from corrosion, dirt or build-up of any kind, and reduce the resistance between the DC terminal and cable connection.
• Test cell voltage, internal resistance, capacity. Test the voltage, internal resistance with Multimeter and test capacity on each cell individually using a battery analyzer or specialized tester.
• Top balance cells before assembly. Before the first use, always charge the cells to full voltage. We recommend to use chargers specially made for LiFePO4 cells. First charge and initial balancing of the whole pack is important step towards long lifetime.
🚫DON’T:
• 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 mix old and new cells. Always use cells from the same manufacturing series and delivery batch for every battery.
• DO NOT operate with loose terminal connections.
We guarantee you’ll be happy with cells you purchase from us. When your cells arrive if you’re not completely satisfied or if you suspect the integrity of the cell has been compromised immediately contact our support team via [email protected] for further assistance.
