KOK POWER LIMITED (KOK), founded in 2011, is pioneer of smart lithium-ion battery systems in China. Our smart batteries can display & monitor the batteries status and thus enable the devices to conserve and use power intelligently with a patented built-in battery management system (BMS) via blue-tooth or other communications through APP or on screen.
KOK is strong in R&D and manufacturing of smart battery systems, widely used in fields such as E-mobility (e-bike, e-scooter, e-skateboard, e-motorcycle, e-tricycle/rickshaw, e-wheelchair, e-golf cart, e-forklift, e-tourist vehicle, RV/caravan,marine,etc.), Energy Storage Systems (solar/wind system, telecom/base station, uninterruptible power supply/UPS/backup system) and engine starter batteries. KOK batteries can readily replace the outdated, bulky and pollutant Lead-Acid / AGM/ GEL/SLA batteries with the latest smart lithium battery technology.
