Yanwen Economic Air Mail shipping way the track number we supply only shows the track in china, when the parcel leave china there is no track anymore, but you can use this track number to contact Customer service to check , or just email to us, we will check for you .

Yanwen Economic Air Mail is a very cheap shipping way , So it may take 40-60days shipping, when you choose the shipping way ,pls accept the long term shipping . Hope you can understand. Thanks!

Integrated 10 low load resistance MOS tube, continuous discharge 40A, 100mA balanced current, for electric drill/sprayer/ LED lights/low power inverter. 4S 16.8V 40A lithium battery protection board (comes with recovery function-AUTO Recovery) Charging voltage: 16.8V - 18.1V Continuous charge current (upper limit): 20A Board Size: 45*55*3.4mm (Standard/Enhance) ,46*60*3.4mm (Balance) Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use) Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery) Note:there is three version . Standard version: for driving current below 60A, power 100W below the drill. Enhance Version :For driving current below 80A,power 135W below the drill

Balanced version: suitable for driving current below 80A, power 135W below the drill. (with balance)

Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!). Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit. Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor\'s positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. Note 4: 4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery. Package: 1* 4S 4A Protection Board
