Bestgo Battery makes high quality Li-ion pouch cells which have thin shape for heat passing and internal resistance reduction. The package foil of cells is a type of aluminum and elastic fibers mixed material which comes from Japan based company (Showa). The aluminum improved the heat passing efficiency, the strong elastic fibers make foil has good strength and tolerence. In extreme condition if cells damaged and generated heat and gas, the package foil can be blown up to hold them but not allow any liquid or gas leak out, this is a very nice safety design.
To enhance the safety reliability, we applied an unique step in manufactuing that is arrange all half-made cells in 75 degree Celsius oven for 2 hours as a high temperature tolerence test. Our unique chemistry formula and nice materials will help cells pass the test. Then we promise pouch cells made by us are quality reliable in high temperature condition as we specified. The electrolyte of our pouch cells are semi-solid state which better than liquid type that may have risk of leak out of cell.
We can put pouch cells into battery module frame, then do laser welding on the cell tabs to the metal sheets on battery modules, by that way we can make sure connection is firmly and good for big current pass. Then we build customized soft-link busbars to connect modules with screws. We can put the battery modules inside metal case, then we build the cell volt wires and temperature sensor wires to the multi-pins connector built on the metal case, so you can use them to connect to your BMS system.
Over the past 10 years, we have got rich experience in customized services. Our senior engineers will give you the best solution according to your detailed requirements!
We have made many customized battery packs of different specifications!
We have CE/UN38.3/MSDS and Sea/Air shipping Certificate for our battery.

For both warranty and after-sale service, the following will be enforced:
Warranty year(s) for this model of battery pack are specified by supplier. During the warranty period, we will take responsibility for the replacement or repair for any of the following issues:
• The whole battery pack cannot be charged or discharged.
• Under the standard testing condition, the capacity is less than 80% in the end of the first year, or 70% in the end of last warranty year (if the last warranty year is provided in the warranty period).
• There is liquid leakage.
• There is some damage on battery pack's case and accessories that are caused by the battery.
However, we will not take responsibility in the following situations:
• Expired warranty period.
• Battery damage as a result of improper handling.
• The battery pack is dismantled and converted.
• There is visible damage to the BMS that was not caused by battery failure.
• Damage caused by using an incorrect charger for the pack.
