3S 40A

Introduction
Product Name: 3 string 12.6V 40A lithium battery protection board
Charging voltage: DC 12.6V~13.6V
Continuous discharge current: 40A maximum (if the heat dissipation environment is not good, please reduce the load current)
Continuous charging current: up to 20A
Balance VersionProduct size: 41*61*4mm
Enhance VersionProduct size: 41*55*4mm
Applicable choice: applicable to the nominal voltage of 3.7V, fully charged 4.2V lithium battery
(including 18650, 26650, polymer lithium battery), can be drilled below 170W
Note 1: Successfully start the drill requires 3 10C-20C power batteries, or 6 5C-10C power batteries (recommended power battery models: sony vtc4, vtc4A, vtc5A, vtc6) OV and 12.6V cable, use Copper wire of 3 square millimeters or more (nickel sheets cannot be used)
Note 2: Strictly connect 0V, 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.
Note 3: When soldering the battery for the first time or when charging is in progress, as long as the single battery exceeds 4.2V, the "430" resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the "430" resistor is severely hot, check if the wrong line is connected.
Hardware preparation
Prepare 3S 12.6V 40A lithium battery protection module, battery, power supply, high power load resistor

The figure below shows the module discharge diagram. The battery is 3 strings. The connected battery needs to meet the 40A discharge current. It can be realized by paralleling the battery or purchasing a battery with a large discharge current. For example, if the battery is 2000mAH and the discharge multiple is 10C, then only 3 strings of 2 are needed and the discharge current is 40A.

The figure below shows the battery charging diagram. The charging voltage is DC12.6V~13.6V. The charging current depends on the battery connected, and the maximum is no more than 20A. The module has a balanced charging path, and the equalization function works only when the battery performance is not much different.



4S 40A

Introduction
Product Name: 4 string 14.8V 16.8V 40A lithium battery protection board
Charging voltage: DC 16.8V~17V
Continuous discharge current: 40A maximum (if the heat dissipation environment is not good, please reduce the load current)
Continuous charging current: up to 20A
Balance VersionProduct size: 45*60*4mm
Enhance VersionProduct size: 44*55*4mm
Applicable choice: applicable to the nominal voltage of 3.7V, fully charged 4.2V lithium battery
(including 18650, 26650, polymer lithium battery), can be drilled below 170W

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.
The figure below shows the module discharge diagram. The battery is 4 strings. The connected battery needs to meet the 40A discharge current. It can be realized by paralleling the battery or purchasing a battery with a large discharge current. For example, the battery 2000mAH, the discharge multiple 10C, then only need 4 series 2 and the maximum current can reach the discharge current 40A, stable discharge requires 4 strings 4 and can be, and need to pay attention to heat dissipation, the discharge battery power will drop rapidly.

3S 60A

Introduction
3S 12.6V 60A lithium battery protection board
Scope: Suitable for lithium battery with 3.7V nominal voltage and 4.2V limited charge voltage. (includes 18650,26650, polymer lithium battery)
Size:41*55*3.4mm(Enhanced version),41*62*3.4(Balanced version).
Weight:8.8g(Enhanced version),9.8g(Balanced version).
Charging voltage: 12.6V - 13.6V
Continuous discharge current (upper limit): 60A (if the cooling environment is not good, please reduce the load current)
Continuous charge current (upper limit): 15A
Enhanced version: suitable for electric drill with starting current below 120A and power below 260W .(without balanced charging function)
Balanced version: suitable for electric drill with starting current below 120A and power below 260W .(with balanced charging function)
Note 1: To successful starting the drill requires three 10C-20C power batteries, or six 5C-10C power batteries ( recommended battery:SONY VTC4,VTC4A,VTC5A,VTC6).Ordinary 18650 battery can not start the drill!Requires 0V and 12.6V copper wire which is no less than 4SQMM(Can not use nickel!!!).
Note 2: When you wiring 0V, 4.2V, 8.4V, 12.6V, plese do it strictly according to the wiring diagram. Do not deliberately make it short circuit.
Note 3: When the battery is charging,the "430" resistance heating is normal,it means the balance circuit is working.If the "430" resistance is also heating without charging,please check if the wrong wire is connected.
