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 271Ah LiFePO4 Prismatic Battery Cells


Are these sales tested & matched & what is their resistance?

Yes these CATL 271Ah LiFePO4 Prismatic Battery Cells are matched and tested before shipping. And AC impedance resistance is less than 0.14±0.05mΩ.

Do these cells require a strap around the case to prevent swelling and capacity loss?

If you are used these cells properly, these cells should not swell or lose capacity. Most of the swelling comes from overcharging or discharging, so that is not useful to use a strap around.

Can this item be mounted in any position?

These cells are sealed and can be put in any position.

Could it be used on an electric skateboard?

It might be too big. It must be secured properly so that it does not vibrate freely. The terminals must be protected from shorting out and causing fires.

This battery for a 12v electric trolling motor (65lb thrust, 120ah rating)?

When you receive these cells, connect them in parallel and do a top balance, by charging them to 3.65 volts. Remove the charger, and leave them 24hr connected in parallel. then connect them in series to reach 12v and use. You MUST use an e-balancer or BMS.
