About this item:
105080 (3.7V 5000mAh) Lithium-ion polymer Battery (LiPo): Each cell outputs a nominal 3.7V. These batteries have fast charge times, reliably hold a charge, and have built-in safety circuitry. They are the best go-to option for any portable project.

Model series Info  105080 10.2 = Thickness, 49.6= Width, 81.8 = length + or -5%
Lithium-ion polymer, or lipo batteries, are thin, light, and powerful. When ultimately charged, they output 4.2V to 3.7V. This battery has a capacity of 5000mAh for a total of about 18.5Wh. If you need a larger (or smaller!) battery, we have an extensive range of Lithium-ion polymer batteries.

The protection circuitry keeps the battery voltage from going too high (over-charging) or having a low over-discharge, which means the battery will cut out when completely dead at 3.0V. It will also protect against output shorts. Even with this protection, it is essential that you only use a LiPo constant-voltage/current charger to recharge them at a rate of 0.5C or less.

Tempero Systems suggests charging at 0.5C or even less, which is 2500mA max for this battery. Like most lipos, these batteries do not have thermistors built in.

The batteries come pre-attached with a 2-pin JST-PH connector and include the necessary protection circuitry. The JST-PH connector has 2.0mm spacing between its pins.

Note: This battery is NOT suitable for RC cars, planes, drones, or other devices that require high power(current); these need a high-rate battery with a continuous discharge rate of 5C, 10C, 15C, 20C, 25C, 30C, 40C, or 50C or higher.

Usage & Precaution:
Lithium-ion and lithium polymer cells are powerful batteries; you should take extreme care when using them. If exposed to abusive conditions, they may get hot, explode, or ignite and cause serious injury. Unfortunately, we can not replace batteries damaged by non-compliant chargers or equipment. Be sure to follow the safety warnings listed below

Do not：
Overcharge: Ensure the charger voltage does not exceed the battery\'s full charge voltage.
over-discharge: Ensure the equipment you use this battery with will not draw more current from that battery than the stated \"Maximum Continuous Discharge Current.\"
leave batteries discharged for an extended period can incur irreversible damage
by placing the battery on fire, heating, or direct sunlight to the battery.
Install the battery backwards so the polarity is reversed.
Connect the battery\'s positive and negative terminal with any metal object,
expose the battery to water or saltwater, or let the battery get wet.
Disassemble or modify the battery. The battery contains safety and protection devices.
Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for damage, loose wiring, or the possibility of short circuits. As with all Lithium-ion polymer batteries and any power source, they should be used by experts who are comfortable working with power supplies.

Note:  Please check your current cable orientation, as there is no  Industry Standard for Cable setup. Wrong orientation can damage the cell and your item.
