Description Based on old version, but added battery protection IC DW01 8205, over voltage, over current double protection. Support output 4.2V to use and charging battery in the same safely. Output to load port on right bottom, charge to battery port on right top. Micro USB charge port, two LED red indicator standby – top right charging – top left Back side XH1.25 2pins (old version is XH2.54) connector for battery, this is not soldered as a option. Input voltage: 5V, charge input better can provide over 1A current, otherwise not good performance. Default charge current is set to 360m, resistor 3.3K. Charge cut-off voltage: 4.2V ± 1% Battery with protections pins B ~ B-/PT. Maximum charge current: 1000mA Battery discharge protection over voltage: 2.5V Battery overcurrent protection current: 3A Updated R4 Version: Fixed over-charge bug mentioned by customer. Thanks a lot for the review! USB port changed to type-C. Add NTC resistor temperature sensing socket, you can remove 0R resistor and add NTC sensor to prevent high temperature risk. More notice for charge please see on this page.
