Product Description

4S 16.8V 40A lithium battery protection board

Scope: Nominal voltage of 3.6V, 3.7V lithium battery

(including 18650,26650, polymer lithium battery)

Charging voltage: 16.8V - 18.1V

Continuous discharge current (upper limit): 40A

(if the cooling environment is not good, please reduce

the load current use)

Continuous charge current (upper limit): 20A

Note: this item is  Enhanced version .If you need other

Version, please contact us. The 3 version price is different

 

Standard version: suitable for starting current below

60A, power 100W below the drill.(Not balanced function)

135W below the drill.(Not balanced function)

 

Balanced version: suitable for starting 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
