2. Static current: less than 30uA
3. Over-discharge voltage range: 2.3-3V
4. Overcharge voltage range: 4.25-4.35V
5. Upper operating current: 6-8A
6. Upper instantaneous current: 10-13A
7. Operating temperature: -40-50 degrees Celsius
8. Storage conditions: -40-80 degrees Celsius
9. Effective life: more than 30,000 hours
10. Internal resistance: less than 100mohm
11. Weight: about 3.4 g
12. Size: about 53 x 17 x 4 mm

Characteristics:
1. Short-circuit protection: can be protected, delayed self-recovery, components for the 2110-CB protection chip and AOD472 x 2 pcs
2. 3A current discharge products, battery discharge multiplier should be more than 3C; multiplier calculation formula: 1C multiplier battery, 2000 capacity is equal to 2AHx1 = 2A upper working current; 3C multiplier battery, 2000 capacity is equal to 2AHx3 = 6A upper working current
3. The described power range applies to the following products: massager battery pack, LED lamp backup power, 12V electronic products, solar street lamp battery pack, monitoring backup power, and other products
4. The battery will be hot in use is the battery multiplier is not applicable, this situation can not be used for a long time, the battery will be quickly damaged

Precautions:
1. Strictly according to the diagram wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+), do not intentionally short circuit
2. After connecting the wires, you need to charge it first before there will be an output
3. 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same, if not the same, please individually fill each group of batteries and then use in series, discharge test, the fastest voltage drop in that group of batteries is poor battery
4. Do not use good batteries and poor batteries together, the closer the capacity/internal resistance of the 3 groups of batteries, the better, (2 good batteries + 1 poor battery effect = 3 poor battery effect)
5. This protection board can not be used for lithium iron phosphate batteries, hernia lamps, electrical drill battery packs, electrical fishing machine battery packs, electrical bicycle battery packs, children car batteries, 775 (4A) or more motors, 1W fisheye LED lamps for the above combination of purchases of the customer, please note
