HIGH SAFETY AND SUPER HEAT DISSIPATION
Our energy storage battery packs use Gotion High-tech Top-ranked A-class automotive LiFePO4 cells for greater safety and longer battery cycle life, up to 5000 cycles at 80% DOD. All-aluminium body design ensures a larger heat dissipation area.
We are responsible for our customers and our brand. All use Gotion High-tech Top-ranked A-class automotive batteries
Use only the highest quality batteries Batteries that use the same standard as the country.
If customer has a bad cell in the battery how do we repair it ?
Battery cells are tested before they are assembled, the chance of a single cell bad is very small After production,all the batteries are tested by using precision electronic instruments before packing and delivery to clients.
If customers receive a battery that has a bad cells, we replace a new battery for free, Cells are difficult to damage in normal use, unless man-made damage.
