Lithium battery overcharge, overdischarge, overcurrent, short-circuit charging protection board 12V 10A

OVERCHARGE VOLTAGE RANGE: 4.25-4.35V±0.05V; OVERDISCHARGE VOLTAGE RANGE: 2.3-3.0V±0.05V

SIZE: 53*17*4MM ;Operating current: 0-10A ; It is recommended to use the operating temperature within 8A: -40-+50°C ;Instantaneous current: 11-13A ; Storage conditions: -40 - +80°C

Quiescent current: less than 30UA ;Effective life: more than 30000 hours; Resistance: less than 100MQ ;Short-circuit protection: protecting, delayed self-healing; SIZE: 53*17*4MM

Lithium battery protection board has a variety of current specifications and other specifications; The more batteries are connected in series, the greater the voltage, the more batteries are connected in parallel, the larger the battery capacity, and the greater the discharge current;

For example, if the working current of the 1S 6A protection board is 6A, if the working current of the electrical appliances you usually use is 5A and below, then you can shoot the 6A protection board; The working current of the electrical appliance is large, and the protection board with high current is taken according to the demand;

In addition, the maximum discharge current of the battery pack is related to the performance of the battery, not that the discharge current of the battery pack can reach 10A with a 10A protection board; Maximum discharge current = multiple of battery capacity x battery discharge coefficient C;

For example, A 18650 BATTERY WITH A CAPACITY OF 3400MAH HAS A DISCHARGE CAPACITY OF 2C; Maximum discharge current = 3400÷1000*2 = 7.4A; 3 strings of 2 and 6 such battery packs;

The maximum discharge current can reach 40A;

Wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B+) strictly according to the diagram, do not deliberately short circuit!

After connecting the cable, you need to charge it first before there will be output.

When connecting 4 groups of batteries in series, please ensure that the voltage of each group of batteries is the same, if it is different, please fill each group of batteries separately and then use them in series. During the discharge test, the group of cells with a fast voltage drop is a poor battery.
