Smart start basic version USB Smart Fast Charge. Universal USB Type C interface, multiple charging methods (Max 1A) , The charge cycle is automatically terminated when the charge current drops to 100mA after reaching the final float voltage. When the battery voltage drops below 4.05V, the charging cycle starts again. When the battery voltage is lower than 2.9V, the battery will be pre-charged with a current of 100mA. Design with high integrated solution, is a high efficiency high frequency synchronous step down DC/DC regulator capable of delivering up to 6A output current. It integrates main switch and synchronous switch with very low RDS (on) to minimize the conduction loss, Internal Soft-start Limits the Inrush Current.

Replaceable 3.7V 1800mAh Lithium Iron Rechargeable Battery (Size 18500) with JST connector with build in protection board to prevent over charge and discharge. Changeable Inner hexagon contactor use direct plug-in design without locking, user can insert or remove fast and smoothly during operating. In order to reduce the phenomenon of flashover and oxidation, Inner spring power contactor come with gold plated and both contactors make by 100% copper to minimize internal resistance.
