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.
