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 the strict monitor, control, and protection by the BMS.
3. Before the first use, always charge the cells to full voltage.
4. We will match (capacity, voltage, resistance) all cells before delivery.
5. The battery is suitable for DIY lovers with experience.


CATL 228Ah Prismatic LiFePO4 Battery Cells


Are you guarantee these battery cells are A grade and what manufacturer it is?

Our A-grade cells are made by CATL, and we will reconfirm their consistency before shipment.

Can these be hooked in series for a 48v system?

Our battery has good consistency. If 16 cells are connected in series, it can become a 48 system.

I have been trying to use similar batteries for home solar in 16 battery series. How do I do this without overcharging some of them?

16 of these batteries in series roughly 54 volts at full charge. To charge them You need a 48-volt solar air which will put out about 60 volts hooked to a charge controller that will shut off at about 54 volts.

How do you charge them?

A single battery cell needs to be charged by a professional tester.

228Ah per cell totaling 912Ah with all four cells?

Yes, but you need to connect four batteries in parallel, so the voltage is still 3.2V, and the capacity is 960Ah, if the series voltage is 12V, the capacity is still 228Ah, you can feel free to DIY according to your needs.
