Description:

4S lithium battery protection board 16.8V 40A (comes with the Recovery function AUTOMATIC Recovery)

  1. The good start of drilling requires three 15C-20C battery power, or six battery power 10C-15C (ordinary 18650 can not start the drill !!).
  2. strictly according to the wiring map 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not short circuit deliberately.
  3. When the brush motor charge is used, try to connect a non-polar capacitor (withstand voltage greater than 25V, capacity 10uF-100uF) to the positive and negative terminals of the motor to avoid the reverse of spike from the motor or break the MOS tube.
  4. 4 groups of batteries in series, please make sure that the voltage of each group of batteries, if it is not the same, please fill each battery separately and then use in series. The test download, the battery that the voltage drop faster than the group is poor.

Specifications:

  • Range: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650, 26650, lithium polymer battery).
  • Charge Voltage: 16.8V-18.1V
  • Continuous Discharge Current (upper limit): 40A (if the cooling environment is not good, please reduce current load)
  • Continuous Charging Current (upper limit): 20A
  • Size: 6.1×4.7cm/2.4×1.85″

Note:

Please allow 1-3mm error due to manual measurement. please make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
