Radiolink CP620 750W 30A Hybrid Balance Charger

There are over a hundred lithium polymer (LiPo) battery balance chargers in the market, but not much has changed for a while, the same user interface and the same programming codes reused.   Radiolink is among the few that has taken the lead to change electric radio control (RC) with the CP620 hybrid charger and rethinking how to improve efficiency and low consumption in todays RC  ■ by


First Impression,  an interesting charge methodology.  The CP620 starts charging through the main power cable with the maximum 30A in series at the suitable charge rate, once any cell is fully charged, it will then automatically changed to the independent balance charge mode charging through the balance port.  This increases the charge efficiency.  With a charge current of 30A, you have a maximum current of 6A for each cell to optimize the charge.

1. Faster
CP620 starts max 30A series charging through power wire and then automatically change to independent balance mode that charging through balance wire once any cell is full, six independent power supply integrated ensure max 6 cells charging for each port, the max charging
current for each cell will be up to 6A, 12 times of the present max balance current 0.5A. A 5000mAh battery takes 15 minutes only.
2. Precise
Voltage precision is 0.001V. By using Radiolink patent independent technology, 20 times of the average data, prolong the battery life.
3.High efficiency
Charging efficiency can up to 97%. 135mA working current ensure the temperature of CP620 always less than 30 degree no matter standby or full power charging.


(1)Power protection
Wrong input protection, even the charger is connected with power source by wrong polarity, the unit will not be damaged. When the input voltage goes down than 11V, the unit will automatically adjust current to hold the battery voltage, which protects power source when connect with autos.

(2)Battery protection
Wrong input protection for every port, it will not damage the battery or the charger when connected with wrong polarity or cut the power supply.

(3)Temperature monitoring
It will start alarming when the temperature goes to the preset data, the unit will automatically lower power output.

Integrate 2 ports charger, automatically charging 2 groups battery. Six independent power supply ensure every group with max six cells battery charging and the max balance current of every single cell is up to 6A.
