Effective Life: more than 30,000 hours
Operating Temperature: -40- +50 degrees
Storage Conditions: -40- +80 degrees
Size: 53 * 16 * 3mm
Short Circuit Protection: protection, delay self-recovery
Applications:
The power range is suitable for the following products: massager battery pack, LED light standby power supply, 12V electronic products, solar street light battery pack, monitor backup power supply, and other products.
Note: 3A current discharge products above, the battery discharge rate to 3C or more.
Magnification Formula:
1C magnification of the battery, 2000 capacity equal to 2AH * 1 = 2A upper limit current. 3C magnification battery, 2000 capacity equal to 2AH * 3 = 6A upper working current.
Note:
1. The battery will heat when using it, it means the battery does not apply , please don't keep using becuase the battery will be damaged soon.
2. The protection board can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery pack, electric fish machine battery pack, electric bicycle battery pack, children's car battery, 775 (4A)motor, 1W fish eye LED light!
3. Please strictly follow the wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B +), do not deliberately short circuit.
4. Please charge after connecting the line, then it will has output.
5. When connecting three groups of batteries, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. Discharge test, the voltage drops quickly when the group of battery time difference battery.
6. Please do not mix the battery and the poor battery together! 3 sets of battery capacity / resistance closer to the better! (Two good batteries +1 a poor battery use effect = 3 poor battery use effect).
Interface:
The wiring is taken from B-
B- connected total negative
B1 connect the positive side of the battery
B + is soldered to the battery positive pole
P-welding line to charge and discharge the negative
P + solder the line to charge and discharge the positive pole.
