Product Functions

Suitable for the following products within the described power range: low-power inverters, massager battery packs, LED light backup power supplies, electronic products, solar street light battery packs, monitoring backup power supplies, and other products.

Precautions for use:

1: Strictly follow the wiring diagram for 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B+), and do not intentionally short circuit!

2: After connecting the cable, it needs to be charged first before there will be output.

3: Products with a discharge current of 3A or higher should have a battery discharge rate of 3C or higher. Ratio calculation formula: For a 1C rate battery, 2000 capacity equals 2AH * 1=2A upper limit working current. 3C rate battery, 2000 capacity equals 2AH * 3=6A upper limit working current.

The battery will heat up during use, which is due to the unsuitable battery rate. This situation cannot be used for a long time, and the battery will quickly damage,

4: When connecting 4 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please fully charge each group of batteries separately before using them in series. During the discharge test, the group of batteries with the fastest voltage drop is a poor battery.

5: Do not mix good and poor batteries together for use! The closer the capacity/internal resistance of the 4 sets of batteries, the better! (The usage effect of 2 good batteries+2 poor batteries=the usage effect of 4 poor batteries)

6: This protective board cannot be used for lithium iron phosphate batteries, hernia lamps, hand drill battery packs, electric fishing machine battery packs, electric bicycle battery packs, children's car batteries, motors above 775 (4A), and 1W fisheye LED lights. Customers who purchase the above combinations are advised to pay attention!
