Important Installation Notice:

To avoid contact resistance, the following points must be observed:

✔️ Thoroughly clean the battery terminals with ethanol or pure alcohol to remove oxide layers.
✔️ The terminals must not be touched with greasy fingers – they must be absolutely grease-free and clean.
✔️ Ideally, the contacts should be cleaned with a brass brush or fine sandpaper (grit 1000).
✔️ The contact surfaces of the cell connectors must also be carefully cleaned.
❌ The use of assembly greases, copper paste, or similar substances must be strictly avoided – they cause contact resistance, which can lead to heat generation and measurement errors during operation. As a result, the full capacity of the cells cannot be utilized.

🔧 Tighten the M6 screws with a torque of 6 Nm.

NOTE

We recommend a maximum discharge down to 2.70 V and a maximum charge of each cell up to 3.50 V.

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.

 

Application

Solar energy storage, solar power system, UPS supply, Engine starting battery, Electric bicycle/motorcycle/scooter, Golf trolley/carts, RV, EV, Caravan So on.
