·       Battery Pack

Capacity Distribution 

In most cases, Nickel-Metal Hydride batteries are used in battery packs when installed in a product. When using these batteries, the type of battery, the number of batteries, the shape of the battery pack, the components in the battery packs, etc. are determined by the specifications (voltage, load current) of the product. In addition, the charging specifications, available space in the battery compartment, operating conditions, etc. must also be considered. At Vapextech, we are committed to promoting battery packs that emphasize battery safety and reliability. We customize the shape of the package to meet the unique requirements of each customer.. If you have special needs, please feel free to contact us.
