Product\nSize: 45153.4mm (Standard), 48203.4mm (Balancing) Charging voltage: 8.4V -\n9.0V Continuous discharge current (upper limit): 20A (If the cooling\nenvironment is not good, reduce the load current use) Continuous charge\ncurrent (upper limit): 10A Balanced version: Suitable for starting currents\nbelow 25A and below 50W power drills, or resistive loads below 168W, with\nbalanced charging function.Notes:Note 1: The successful start of power drill\nrequires two 10C-20C power batteries, or four 5C-10C power batteries (ordinary\n18650 can not start drill! ! !); 0V and 8.4V cable, use 2 square mm Above\ncopper wire (cannot use nickel plate!!!) Note 2: Connect 0V, 4.2V, 8.4V\naccording to the diagram strictly. When connecting the battery for the first\ntime, it needs to be charged before output. Note 3: When the battery is\ncharged, \"430\" resistance heating is a normal phenomenon, indicating that the\nequalizing circuit is working; if the \"430\" resistance is also heating in the\nstate of not charging, please check whether the wrong line is connected. For\nsome customers with poor electronic foundation, please explain: Do not mix\ngood batteries and bad batteries together! The capacity\/internal resistance of\n2 batteries should be as close as possible! (1 good battery + 1 bad battery =\n2 battery use effect).Packet Contains: 5pcs x 2S 20A 7.4V 8.4V 18650 Lithium\nBattery Protection Board BMS Balance Version\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003e2S20A2S 20A 7.4V 8.4V 18650 Lithium Battery Protection Board BMS Balance Version.
