Description

Product selling point:1. Made of high quality material, durable and practical.2. The appearance is small and beautiful.3. Wide application.4. It has the functions of overcharge, overdischarge and short circuit protection.6. This product has the function of preventing reverse charging in the use of the motor.Parameter:Working voltage: 7.5V-12.6VCurrent: 20A (20A is just an instant start current, 20A cannot be used for a long time)Description: Over-discharge protection voltage 7.5V, full 12.6VIllustrate:Buyers need to match the capacity, internal resistance and voltage of the battery when assembling the battery pack. The consistency needs to be good, otherwise the battery pack will not be able to be charged, or the battery will not be fully charged, or the discharge will be incomplete. Many buyers say why the previous battery can be charged and this board cannot be charged, that is, our board does not have a balanced discharge resistance. If the voltage of a certain string of batteries is higher than the others, it will stop charging or fail to charge during discharge. After the power is completely discharged, the protection board with the discharge equalization resistor can indeed be charged, but it will also speed up the aging of the battery, which is even worse for the battery. Therefore, our protection board is suitable for more professional personnel to use.Package Included:1* 3S lithium battery protection board
