The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Joom’s policies and EU Product Safety and Compliance laws. Description Introduction (1) Product Description: This product is used to charge/discharge 3 groups of lithium batteries in series, and each group can be connected in parallel with multiple lithium batteries. It can withstand continuous charging current of 20A, continuous discharge current of 40A, and instantaneous current of less than 80A. During use, the heat dissipation conditions are better. If the heat dissipation conditions are not good, please reduce the current use, and do not make the board feel hot. 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 for battery charging and discharging of electric drills, sprayers, LED lights, low-power inverters, inverters and other products. Introduction (2) Product parameters: Product model: HW-552; Size: 41*60*1mm; Charging voltage: 12.6V-13V; ◆Maximum working current: 60A (very good heat dissipation); ◆Continuous charging current (upper limit): 20A; Continuous discharge current (upper limit): 40A; Overcurrent Protection: 125A; Overcharge detection: 12.8V (for 3 sets 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-- +85C; Storage conditions: -40-- +125C. (3) Instructions for use: Three usage scenarios A. Charging (overcharge protection) (1) First of all, the wiring should be strictly in accordance with the above diagram. The wire used should be good and the contact should be good, 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 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 turn off the battery charging circuit, which is the overcharge protection. (4) When the voltage of the battery pack drops below 12.3V, the overcharge protection contacts, and the board will turn on the battery charging circuit again, which is the overcharge release. (5) If the overcurrent/short circuit protection of the board is turned on for some reason during the charging process, you need to remove the connection of the load end, then turn off the power supply and restart to cancel the overcurrent protection. You can also disconnect the load, wait a few seconds, the overcurrent protection will automatically cancel. B. Discharge (over-discharge protection) (1) The wiring should be strictly in accordance with the above...
