Sobre este producto
- Balanced version charging: refers to the unbalanced voltage of the battery terminals due to the individual differences and temperature differences of the battery during the use of the battery. The battery is activated and charged to balance the characteristics of each battery in the battery pack and prolong the battery life.
- Charging voltage: DC 12.6V~13.6V
- Continuous discharge current: maximum 40A (if the heat dissipation environment is not good, please reduce the load current);Continuous charging current: maximum 20A.
- Support overcharge protection,overdischarge protection,overcurrent protection and short circuit protection.
- The protection board is suitable for lithium-ion batteries, and can also be used for ternary batteries, manganese acid batteries, and cobalt acid batteries.

Massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring backup power supply, and other products. Attention: For products with a discharge current of 3A or higher, the battery discharge rate should be above 3C. Calculation formula for multiplication: For a 1C multiplication rate battery, the 2000 capacity is equal to 2AH * 1=2A working current. A 3C rate battery with a capacity of 2000 is equivalent to a working current of 2AH * 3=6A. When the battery heats up during use, it means that the battery rate is not suitable. In this case, it must not be used for a long time as the battery will quickly damage. Attention 1: Strictly follow the diagram to wire 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B+), and do not intentionally short circuit! Note 2: After connecting the wires, it is necessary to charge first before there is an output. Note 3: When connecting three sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If it is different, please fully charge each set of batteries separately before using them in series. The group of batteries with a fast voltage drop during discharge testing is a poor battery. For some customers with poor electronic foundations, it is important not to mix good and poor batteries together! The closer the capacity/internal resistance of 3 sets of batteries is, the better! (2 good batteries+1 poor battery usage effect=3 poor battery usage effect). Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying. The properties of the lithium battery protection board: Overcharge voltage range: 4.25-4.35v ± 0.05v Size: 41 * 60 * 4.0mm Overdischarge voltage range: 2.3-3.0v ± 0.05v Working current: 0-25A Working temperature: -40-- -+50 ℃ Instantaneous current: 35-40A Storage conditions: -40--+80 ℃ Static current: less than 30uA Effective life: greater than 30000 hours Internal resistance: less than 100m Ω Short circuit protection: Protectable, delayed self recovery.
