Lithium use common sense:

1You must use a standard lithium battery charger4 .2VCharging.

2Prohibit large current discharge(With protection board will automatically control).

3Prohibit discharge, single cell voltage should not fall below2 .5V (With protection board will automatically control).

4Prohibited disassemble , short-circuit the battery , most likely caused by a short circuit fire.

5, Temperature-20 –60.


1Rechargeable battery.Had prohibited.Discharge .

2, Without the board \\\’s battery is below2.75VWhen use is prohibited on again.Must be charged. (Easy to over-discharge).

3, Without board when the battery is fully charged, must win.Otherwise(Easy to overcharge).

4Use qualified charger.

Charge Description :

Charge limit voltage : 4.25 0.05V operating voltage cut-off : 2.75V

Standard Charge Current : (0.5C) Maximum charge current : (1C)

Standard discharge current : (0.2C) Maximum continuous discharge current : (2C)

Each use of the best complete charge and discharge cycles help extend battery life and maintain performance, not free to charge the battery disconnect the power;For those who want long-term without the battery is fully charged again to remain insulated storage, and regularly on a single charge .

Product parameters :

1, With a newACommodities battery cell voltage3 .7V

2,After the belt protection boardSupport overcharge, over-discharge protection, voltage2.75-4.20V
