Requirements for rechargeable batteries:
Available battery: 18650 battery, cell phone battery, flat battery, MP3 battery, etc. 3.7V 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.
Not available Battery: dry batteries, batteries, 1.2V rechargeable batteries, nickel-metal hydride batteries, 3.2V lithium iron polymer lithium batteries.
Product installation should pay attention to the following points:
the battery should be in parallel, the voltage between 3.2-4.2V to work, 18650 flat and polymer batteries can be;
the battery is connected to the motherboard B + negative access B-, installed anti-burning motherboard;
the old and new batteries, models, inconsistent battery brand can not be mixed.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
