📖 Product Information Overview

The Smart Battery Charger is a fully automatic 4 steps charging with Pre charge, CC, CV and Floating / shut-off intelligent battery charger. Charging faster and accurately than conventional big and heavy chargers. The pre-charge step can active your low voltage battery and protect your extremely discharged batteries.

These chargers have worldwide input voltage 110 - 240Vac, some models was designed with PFC circuit. Charger automatically operates on voltage of 110Vac or 240Vac when user connects it to the local wall socket. We customize input plug and output connector types by customer's request and meet local applications fully.

Smart battery chargers are widely applied to electric vehicles including e-bikes, e-scooters, e-mobility, e-skateboards, e-motorcycles, e-golf carts, electric floor sweepers etc. Whether powered by lithium (LiFePO4, Li-ion, LiMo2, Li-polymer etc.) or lead acid (AGM, SLA, GEL, Flooded, Deep cycles etc.), our charger can charge it with high speed and intelligent method.
