HW-544Introduction 1Product name: 3 strings of 12.6V 60A lithium battery protection board (balanced charge)Product model: HW-544Charging voltage: DC 12.6V~14VContinuous discharge current: Maximum 60A (If the heat dissipation environment is not good, causing the module to overheat, please reduce the load current to use)Continuous charging current: maximum 10AIntroduction 2The figure below is the module discharge diagram. The batteries are in three strings. The connected batteries must meet the 60A discharge current. This can be achieved by connecting batteries in parallel or purchasing batteries with high discharge current. For example, if the battery is 2000mAH and the discharge multiple is 10C, then only 3 strings are needed, and the maximum current can reach the discharge current of 60A. Stable discharge requires 3 strings and 6 parallels, and attention needs to be paid to heat dissipation, and the discharged battery capacity will drop rapidly.The figure below is the battery charging diagram, 3 strings of batteries, fully charged 12.6V. The charging power supply voltage is DC12.6~14V, the charging current depends on the current value set by the charging power supply and the battery power, and the maximum does not exceed 10A.Note 1:To start the electric drill successfully, you need 3 power batteries of 10C-20C, or 6 power batteries of 5C-10C (recommended power battery models: SONY VTC4, VTC4A, VTC5A, VTC6)For 0V and 12.6V connection lines, use copper wires of 4 square millimeters or more (nickel sheets cannot be used!).Note 2:Successfully starting the motorcycle has higher requirements on the battery! Need 6 15C-20C movePower batteries, or 12 10C-15C power batteries (recommended power battery models: SONY VTC4, VTC4A, VTC5A.VTC6), and the motorcycle needs to have a charging voltage regulator circuit.Note 3:Wire 0V, 4.2V, 8.4V, 12.6V strictly according to the diagram, and do not touch any components on the board when soldering the wire, and do not intentionally short-circuit.Note 4:When the battery is being welded for the first time or is being charged, as as a single battery exceeds 42V, the "430" resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the "430" resistor is seriously hot (you can't touch it when it is too hot), please check whether it is connected to the wrong wire.HW-552Introduction (1)Product description:This product is used to charge/discharge 3 groups of lithium batteries in series, and each group can connect multiple lithium batteries in parallel. It can withstand a continuous charging current of 20A, a continuous discharge current of 40A, and an instantaneous current of less than 80A. During use, the heat dissipation conditions should be good. If the heat dissipation conditions are not good, please reduce the current to use, and do not make the board feel obvious. In the process of charging and discharging, it has the functions of overcharge protection, overdischarge protection, overcurrent protection and short circuit protection. This product can be used to charge and discharge batteries in electric drills, sprayers, LED lights, low-power inverters and other products.Introduction (two) product :?Product model: HW-552;?Size: 41*60*1mm;?Charging voltage: 12.6V-13V;?Maximum working current: 60A (excellent heat dissipation conditions);?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 sets of batteries);?Over-discharge detection: 2.4V (for 1 battery);?Over-discharge release: 3.0V (for 1 battery);?Short circuit protection: Yes;?Working temperature: -40-- +85℃;?Storage conditions: -40-- +125℃.Introduction (3) Instructions for use:Three usage scenariosA. Charging (overcharge protection)(1) First of all, wiring must be strictly in accordance with the above diagram. 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 generate a lot of heat, which will affect the performance of the board.(2) Connect a 13V power supply to the charging terminal of the board and start charging.(3) The board will detect the total voltage of the three groups of batteries in series. When the voltage reaches 12.8V, the board will close the battery charging circuit, which is the overcharge protection.(4) When the battery pack voltage drops below 12.3V, the overcharge protection contacts, and the board will open the battery charging circuit again, which is the release of overcharge.(5) If the over-current/short-circuit protection is enabled on the board due to some reasons during the charging process, you have to remove the connection at the load end, then turn off the power and restart, then the over-current protection can be cancelled.You can also disconnect the load and wait a few seconds, the overcurrent protection will be automatically cancelled.B. Discharge (over discharge protection)(1) Wiring must be strictly in accordance with the above diagram. 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 generate a lot of heat, which will affect the performance of the board.(2) Connect the load, and the lithium battery pack supplies power to the load through the board. In the case of good heat dissipation, the board can withstand a continuous current of 40A. If the heat dissipation is very good, it can even reach 60A.(3) During the process of discharging, when it is detected that the voltage of a certain group of batteries has fallen to the over-discharge voltage limit, the board opens the over-discharge protection and closes the discharge. Note that the battery voltage detected during the discharging process of the board will be lower than the voltage at both ends of the battery measured by a multimeter. This is caused by the wires and the inside of the battery, so after turning on the over-discharge protection, you use a voltmeter to measure the voltage at both ends of the battery. , Often higher than 2.4V. In addition, the poor connection between the "0V" terminal on the board and the negative electrode of the battery will also cause the over-discharge protection voltage to be higher than 2.4V.(4) When the battery voltage rises above 3V, the over-discharge protection is released. If the over-discharge protection is not released, the load can be disconnected, and the over-discharge protection will be released.C. Overcurrent protection.When the current is too large, the board opens the overcurrent protection, the line connection is disconnected, and the charging or discharging is stopped.Conditions for successful start of electric drill:(1) The discharge current of the battery must reach the lowest starting current of the electric drill;(2) The connection between the battery pack and the protection board should be as short as possible, and the wire core should be as thick as possible;HW-296Introduction (1)Product name: 4 series 16.8V 40A lithium battery protection boardProduct model: HW-296Charging voltage: DC 16.8V~17VContinuous discharge current: Maximum 40A (If the heat dissipation environment is not good, please reduce the load current to use)Continuous charging current: 20A maxProduct size: 44*55*4mmApplicable options: suitable for lithium batteries with a nominal voltage of 3.7V and a full charge of 4.2V(Including 18650, 26650, polymer lithium battery), can carry electric drill below 170WNote 1:To successfully start the electric drill, 4 10C-20C power batteries, or 8 5C-10C power batteries, 0V and 16.8V connecting wires, and copper wires of more than 3 square millimeters are required.Note 2:Wiring 0V, 4.2V, 8.4V strictly according to the diagram. 12.6V, 16.8V, do not touch any components on the board during soldering, and do not intentionally short-circuitIntroduction (2)The figure below is the module discharge diagram.
