Product Features:
The lithium battery protection circuit board uses a highly integrated intelligent lithium battery protection circuit board, integrated chip, performance is better than the cover panel consisting of discrete chips. Can complete 3/4/5 string polymer lithium battery, triple lithium battery, lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, charge and discharge protection, over current, short circuit, overheat protection and equalization function . It adopts 4 milliom ultra-low internal resistance MOS tube, which has low internal resistance and high efficiency. It is suitable for use in a variety of applications such as inverters, DC motors, power tools and street lights. Usually suitable for the same mouth and mouth.

Notes:
1. Select the appropriate cover plate according to the actual battery type and serial connection. The protection card for various serial numbers cannot be used universally. The protection board can switch the battery serial number with a jumper. For details, see Description of parameter settings.
2. Before installing the protection board, the battery must be well matched, and old and new batteries cannot be mixed.
3. Please remove the cable before wiring and connect all wires, and then confirm the correct wiring before connecting the cable. When wiring, the wiring control circuit is gradually connected from the negative pole of the battery. For a thick line, select the appropriate square wire according to the actual load value.
4. When the operating current is too high, add tin to the tin-plated part of the front and back of the circuit board or thicken the copper wire to increase the overcurrent potential of the circuit board. Otherwise, Copper Leather on the circuit board will be led to current due to excessive current. Skin or burns.
5, you need the temperature protection function, you need to add a 10K NTC resistor (see description). By default, the factory does not have a resistor to protect against temperature.
6. This cover plate has an additional overcurrent delay. If the instantaneous inrush current of the load is very large and leads to improper protection, you can choose a secondary overcurrent protection delay to reduce the occurrence of false protection.
