NOTE!

1. One Cell will come with 1busbar, 2 screw caps, 2 flange nuts, 1epoxy resin board for free. (e.g. 4 pcs Cells will come with 4 pcs busbars, 8 pcs flange nuts, 4pcs epoxy resin boards. )

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.

Warranty

The warranty period is 5 years from the date you receive.

We only replace new cell for free due to the failure of manufacturing.

Before the shipment, we will detect the cell voltage/resistance/appearance and other issues. we can only ensure that single cell is good before the shipment.

When arrival you can test the cells within 1 week, if you found problems please contact us for refund or replace. Any return behavior buyers need to be responsible for shipping fee.

Remark

Please read carefully all the description before taking orders, the battery is suitable for DIY lovers with experience, people who are not familiar with the safe use of lithium battery knowledge, please go to our shop to buy the finished product.

DIY battery pack must get the cells balanced (same voltage ) before assembly.
And we don’t accept refund for buyers who don’t know how to assembled or unbalanced assembly.

Please use the correct BMS during assembly. We don’t accept refund for the problem caused during assembly process or after the assembly. Such as not use the BMS, the BMS connected to the wrong wire lead to battery damage, charger failure, the assembly error or unbalanced assembly, etc.

Before assembling, please make sure use the same capacity cell and use the same brand of the cell. It is forbidden to mix cells with different capacity and brand in the same battery system. Otherwise, we will not be responsible for quality assurance.
