Continuous discharge current: maximum 40A (if heat dissipation environment is not good, please reduce the use of load current)
Continuous charging current: maximum 20A
Applicable Choice: For lithium batteries with nominal voltage of 3.7V and charge of 4.2V (including 18650, 26650 and polymer lithium batteries), with electric drill below 170W.
Product size: 60mm*40mm*2mm/2.36*1.57*0.07\'\'
Packing weight: 12g
Warm Tips:
1. Successful start-up of the drill requires four 10℃-20℃ power batteries, eight 5℃-10℃ power batteries, V and 14.4V connections, using copper wires of more than 3 square millimeters.
2. Connect 0V, 3.6V. 7.2V, 10.8V, 14.4V strictly according to the figure. When welding the wire, you can\'t touch any components on the board, and don\'t intentionally short circuit.
3. When welding batteries or charging, as long as a single battery exceeds 3.6V, * 360 "resistance will heat and discharge (discharge to 3.59V or so stops heating). If the "360" resistor is heated seriously (too hot to touch), please check whether the wrong connection is made and whether the wrong 4.2V battery is used.
