Massager battery pack, LED light standby power supply, 12V electronic products, solar street lamp battery pack, monitor backup power supply, and other products.
Note: 3A current discharge products above, the battery discharge rate to 3C or more.
Magnification calculation formula: 1C magnification of the battery, 2000 capacity is equal to 2AH * 1 = 2A operating current.
3C magnification battery, 2000 capacity equal to 2AH * 3 = 6A operating current.
For some of the poor basis of electronic customers to explain: Do not put a good battery and poor battery mixed with the use of three groups of battery capacity / resistance closer to the better! (2 good battery +1 a poor battery use effect = 3 poor battery use effect).
In the use of the battery will heat is the battery does not apply, this situation must not be long-term use, the battery will soon be damaged.
Note 1: strictly according to Figure wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B +), do not deliberately short circuit!
Note 2: after the need to charge the first line, will have output.
Note 3: 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please single DU full of batteries and then used in series. Discharge test, the voltage drop Z fast that group of batteries is poor battery.
