2S 20A 7.4V 8.4V 18650 Lithium Battery Charger Protection Board PCB BMS Board Balanced / Standard 20A Current Module For DIY
1. Applicable Scope: Suitable for lithium batteries with nominal voltage of 3.7V and fullvoltage of 4.2V(including 18650,26650, polymer lithium batteries, without limitationon the dimensions)
2. Product Size: 45*15*3.4mm (Standard), 48*20*3.4mm (Balancing)
3. Charging Voltage: 8.4V - 9.0v
4. Continuous Discharge Current (upper limit): 20A (lf the cooling environment is notgood, reduce the load current use)
5. Continuous Charge Current (upper limit): 10A
6. Standard Edition: Suitable for starting drills with currents up to 25A below 50w, orresistive loads below 168W.
7. Balanced Version: Suitable for starting currents below 25A and below 50W powerdrills, or resistive loads below 168W, with balanced charging function.
Note 1: The successful start of power drill requires two 10C-20C power batteries, orfour 5C-10C power batteries (ordinary 18650 can not start drill! ! !); 0V and 8.4Vcable, use 2 square mm Above copper wire (cannot use nickel platel!!!)
Note 2: Connect 0V, 4.2V,8.4V according to the diagram strictly. When connecting thebattery for the first time, it needs to be charged before output.
Note 3: When the battery is charged, "430"resistance heating is a normalphenomenon, indicating that the equalizing circuit is working; if the430"resistance is also heating in the state of not charging, please check whether the wrong line is connected.
For some customers with poor electronic foundation, please explain: Do not mix good batteries and bad batteries together! The capacity/internalresistance of 2 batteries should be as close as possible! (1 good battery + 1 badbattery = 2 battery use effect).
