NOTE
Note1:Successfullystartthedrillrequires310C-20Cpowerbatteries, or65C-10C power batteries(recommended power battery models:sony vtc 4, vtc4A, vtc5A, vtc 6) OV and 12.6V cable, use Copper wireof3squaremili meters or more(nickel sheets can not be used)
Note2:Strictlyconnect0V, 4.2V, 8.4V, 12.6V according to the diagram.Do not touch any components on the board when soldering the wire.Do not intentionally short circuit.
Note3:Whensolderingthebatteryforthefirsttimeorwhenchargingisinprogress, as long as the single battery exceeds 4.2V, the"430"resistor will heat up and discharge(discharge to about 4.19Vtostop heating) .If the"430"resistor is severely hot, check if the wrong line is connected.
