Product Information

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 diation environment is not good, please reduce the load current)

Continuous charging current: up to 20A

Balance Version Product size: 41*61*4mm

Enhance Version Product 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:

Succefully 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 the wire. Do not intentionally short circuit.

Note 3:

When the battery for the first time or when charging is in progre, as long as the single battery exceeds 4.2V, the "430" will heat up and discharge (discharge to about 4.19V to stop heating). If the "430" is severely hot, check if the wrong line is connected.

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 diation environment is not good, please reduce the load current)

Continuous charging current: up to 20A

Balance Version Product size: 45*60*4mm

Enhance Version Product 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 succeful 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 (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the re 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.

Introduction

Product name: 3S lithium battery protection board 60A enhanced version

(1) Product descrtion: This product is used to charge / discharge three groups of lithium batteries in series, and each group can connect multle lithium batteries in parallel. It can Withstand continuous charging current 20A, continuous discharge current 40A, instantaneous current below 80A. used During the proce, the heat diation conditions should be good. If the heat diation conditions are not good, please reduce the current usage and do not let the board The child has a noticeably hot feeling. During charging and discharging, it has overcharge protection, overdischarge protection, and overcurrent Protection, short circuit protection. This product can be used in electric drills, sprayers, LED lights, low power re. Charge and discharge batteries of transformers and other products.

(2) Product parameters:

◆ Product model: HW-552;

◆ Size: 41 * 60 * 1mm;

◆ Charging voltage: 12.6V-13V;

◆ Maximum working current: 60A (heat diation conditions are very good);

◆ Continuous charging current (upper limit): 20A;

◆ Continuous discharge current (upper limit): 40A;

◆ Overcurrent protection: 125A;.

◆ Overcharge detection: 12.8V (for 3 groups of batteries);

◆ Overcharge release: 12.3V (for 3 groups of batteries);

◆ Overdischarge detection: 2.4V (for 1 group of batteries);

◆ Overdischarge release: 3.0V (for 1 group of batteries);

◆ Short circuit protection: Yes;

◆ Working temperature: -40-- + 85C;

◆ Storage conditions: -40-- + 125C.

(3) Instructions for use:

Three usage scenarios

A. Charging (overcharge protection)

(1) First, the wiring must be strictly in acconce with the above figure. Use good wires and good contact Good, because even a small resistance will cause a large current to flow. Preure drop and generate a lot of heat, which affects the performance of the board.

(2) Connect the 13V power supply to the charging end of the board and start charging.

(3) The board will detect the total series voltage of the three groups of batteries. When the voltage reaches 12.8V, the board will Turn off the battery charging circuit, this is the overcharge protection

B. Discharge (over discharge protection)

(1) Wiring must be performed strictly in acconce with the figure above. Use good wires and good contact because even if the resistance is not too large, when a large current flows, it will cause a large voltage drop, and Generates a lot of heat, which affects the performance of the board.

(2) Turn on the load, and the lithium battery pack supplies power to the load through the board. With good heat diation, the board can Withstand a continuous current of 40A, if the heat diation is very good, even to reach 60A.

(3) During the discharging proce, when it is detected that the voltage of a certain group of batteries drops to the over-discharge voltage limit, the board

Turn on over-discharge protection and turn off discharge. Note that the battery voltage detected during board discharge Will be lower than measuring the voltage acro the battery with a , which is caused by the wires and the battery, So after the over-discharge protection is turned on, you use a to measure the voltage acro the battery, which is often higher than 2.4V. In addition, the "0v" terminal on the board and the battery indirect line are not good, which will cause over discharge.The protection voltage is higher than 2.4V.

(4) When the battery voltage rises above 3V, the over-discharge protection is released. If over-discharge protection is not available In addition, the load can be disconnected and the over-discharge protection will be released. C. Over current protection. When the current is too large, the board turns on over current protection, the line connection is disconnected, and the charging or Discharge.

Succeful start of electric drill conditions:

(1) The discharge current of the battery must reach the minimum starting current of the electric drill;

(2) The connection between the battery pack and the protection board should be as short as poible, and the wire core should be as thick as poible;

(3) Other conditions are found and supplemented separately.
