Radiolink CM210 15W 1.5A 2S LiPo Balance Charger with USB Type-C for RC Airplane, Car, Boat, SCX24, SCX10, Gel Blaster
The Radiolink CM210 is a compact 15W balance charger designed for 2S 7.4V LiPo batteries, delivering up to 1.5A charging current via USB Type-C. It fits RC transmitters, cars, boats, SCX24/SCX10, and gel blasters. With software safety logic, over-temperature protection, and automatic trickle charging, it aims to extend battery life while reducing the risk of overcharging.
What batteries does the CM210 support?
This charger works exclusively with 2S LiPo batteries that have a standard 3-pin PH2.54 balance connector. It is not compatible with 1S, 3S, or other chemistries. The charger automatically detects the battery capacity and adjusts the charging current to an optimal 1C rate after reaching 4.16V per cell, then switches to trickle mode to top off safely.
Charging safety features and protections
The CM210 includes multiple layers of protection. A software logic safety algorithm halts charging if a circuit error is detected. Over-temperature protection reduces current when the battery PCB gets too hot. Voltage precision is ±0.02V, ensuring each cell stops at 4.2V — minimizing the risk of overcharging or undercharging. The charger also supports trickle current recovery for over-discharged batteries (below 3.0V per cell), helping restore capacity safely.

Frequently asked questions
Can I charge a single-cell LiPo with the CM210?
No. The CM210 is designed specifically for 2S (two-cell) LiPo batteries with a balance connector. It cannot charge 1S or 3S packs.
What power sources can I use to power the charger?
Any USB Type-C power supply works — including a computer USB port, a USB wall adapter, or a car USB charger. The charger is compact enough to carry anywhere.
How does the charging indicator work?
The CM210 uses a charging indicator to show when the battery is full. Many factory chargers require you to guess by feel or time, but this charger gives a clear visual signal.
Will the CM210 charge over-discharged batteries?
Yes. If the charger detects a single cell voltage below 3.0V, it activates a battery repair mode that trickle charges to restore capacity safely. Note that severely damaged batteries may not recover fully.
