DESCRIPTION:

Low power inverter, massager battery pack, LED light standby power supply, 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 calculation formula: 1C magnification of the battery, 2000 capacity is equal to 2AH * 1 = 2A upper limit current.

3C magnification battery, 2000 capacity equal to 2AH * 3 = 6A upper working current.

In use, the battery will heat is the battery does not apply, this situation can not be long-term use, the battery will soon be damaged.

Note 1: strictly according to map wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B +), do not deliberately short circuit!

Note 2: after the need to charge the first line, will have output.

Note 3: 4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then used in series. Discharge test, the voltage drop is fast that group of batteries is poor battery.

(2 good battery + 2 poor battery use effect = 4 poor battery use effect). 4 battery capacity / resistance closer to the better! (2 good battery +2 poor battery use effect = 4 poor battery use effect).

The lithium battery protection board properties:

Model: HX-4S-D20 overcharge voltage range: 4.25-4.35v ± 0.05v
