Radiolink CP620 750W 20A Battery Charger Hybrid Balance Charger For RC Models Specification: Brand Name: Radiolink Item No.: CP620 Item Name: Hybrid Balance Charger Input voltage: 10.5~30V Power output: 750w Charge current: max 20A Balance current: max 6A Discharge current: 0.1~3A Compatible battery type: 1~6S LiPo\/1~16NI-MH\/ lead-acid cell, nickel-cadmium cell and the lithium-ion battery Lithium charging mode: mixed charging, large current series charging, independent balance Voltage accuracy: 0.001V Charge port: 2 ports, automatically charging in cycle mode Working mode: cycle\/alternate\/discharge\/storage mode Features: 1. Fast CP620 starts max 20A 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. 4.Safe (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. 5.Majordomo 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. 6.Closely Measures the battery cell capacity and resistance, records the original voltage and adjust to the best charging voltage etc. Package Included: 1 x CP620 Hybrid Balance Charger
