Product overview
The RadioLink Electronic Limited CM210 Balance Charger is a portable charger for 2S LiPo batteries, measuring 40.5 × 21 × 15 mm and weighing 9 g. It accepts 5V DC through USB Type-C and uses series charging with bypass balancing. Supported power sources include adapters, computers, mobile power supplies and car chargers, with charging current adjusted automatically to the supply. The supplied package contains the CM210 charger, a Type-C charging cable and a packaging bag.
The CM210 provides a maximum pulse charging current of 1.5A and dynamic balancing throughout charging. A 500mAh 2S LiPo battery can reach full charge in 20 minutes under laboratory conditions; the time depends on the power supply’s maximum current. Repair mode activates below 3.0V per cell, while trickle charging begins near full charge at 4.16V. Protection functions stop charging on circuit or battery errors and reduce current when circuit temperature exceeds the safe value. LEDs indicate charging progress.
