  • Size : 69 X 32 X 8 mm (LxWxH)

Requirements for rechargeable batteries:

  • Batteries Can be used with module: 18650 battery, cell phone battery, flat battery, MP3 battery, etc. 3.7V-4.2V polymer lithium battery can be single section (chip) power supply, can also be multi-section (chip) parallel power supply (not in series, not in series ). (Note: increase the capacity in parallel, the series is to increase the voltage, can only be used in parallel!)
  • Can be parallel 2-6 18650 battery.
  • Batteries Can not be used with module: dry batteries, batteries, 1.2V rechargeable batteries, nickel-metal hydride batteries, 3.2V lithium iron polymer lithium batteries.

18650 Lithium li-ion battery dual micro usb booster board installation should pay attention to the following point

  1. The battery should be in parallel, the voltage between 3.2-4.2V to work, 18650 flat and polymer batteries can be.
  2. The battery is connected to the motherboard B + negative access B-, installed anti-burning motherboard;
  3. The old and new batteries, models, inconsistent battery brand can not be mixed.

Safe Design:

1.Power has designs of overcharge, overdischarge, short circuit protection, does not need to worry about the time of charging
2.Intelligent Output.When equipment is fully charged, it will stop charging automatically to prevent from overcharging
3.Power has multiple safe designs.Output voltage and current is stable, never to damage user’s device
4.Operating temperature range is wide (-20 Clecius—50 Clecius),can provide over temperature protection
Function Feature: with a hightlight LED lamp (long press or double click power key can start)
Electricity Quantity Display:4 class LED light display electricity quantity, non-operating state will be intelligently off.

Charging Display:

When charging 0-25% one light is on,other light is off; 25%–50%, the second light flashes,the first light is continously on;50%– 75%, the third light flashes,front two lights are continuously on;75%—100%;the fourth light flashes, front three lights are continuouly on. And four lights are on charging to 100%.

Installation Introduction:

1.Circuit board B- connects power negative, B+ connects positive.Don’t inversely connect,it will result in burning of board. Power is series soldering,so please make sure the insulation between power and circuit when install the battery
2.Double press the switch,flashlight LED light starts,then double press tyrn it off
3.Double press starts flashlight,then press once,light will be lighting.Then touch once start SOS mode,and press one more time turn off LED
4.2A output is not continuous current,it changes according to USB connecting load automatic current output
5.Insurance reisitor.If battery connects incorrectly,the polarity will burn.
