Special Battery Manufacturer

Special Environment | Special Applications | Custom Design

Special lithium-ion batteries have to be customized and have more requirements than ordinary lithium-ion batteries because they have to adapt to relatively harsh working conditions and temperature ranges. For 19 years, LARGE has focused on the customization of special lithium battery. According to the actual needs of customers, we can provide battery cell +BMS+ battery structure integrated lithium battery customization solutions and products.
Special lithium battery is roughly divided into four fields: low temperature lithium battery, explosion-proof lithium battery, high temperature lithium battery and high ratio lithium battery.
