18650 Cylindrical Battery 2000mAh Lithium Ion Battery For Home Appliances

The most common type of lithium battery is the li-ion battery. This technology has a number of advantages over other battery technologies:

Li-ion battery have a high energy density, which means they can store a lot of energy in a small space.
They have a high power density, which means the li-ion battery can provide a lot of power (current) for a short period of time.
They have a low self-discharge rate, which means they lose very little of their charge when not in use.
The li-ion battery are lightweight and compact, which makes them ideal for portable electronic devices.

FQA:

1. What is the maximum voltage for 18650?The max charge voltage of the 18650 battery is 4.2V, and the maximum voltage can reach 8.4 volts(4.2V x 2) when two 18650 batteries are connected in series. These batteries have to be connected in series. You'll need to connect three 3.7V 18650 in a series to get a nominal voltage of 12V.

2. Can I charge 18650 with USB?
It has a built-in micro-USB port, enabling you to charge the battery from a wall outlet, power strip, or computer using a separately available USB cable, negating the need for an external charger.

3. Can you use any 18650 battery for flashlight?
Battery Voltage. This means that although many flashlights can swap between 1x 18650 or 2x 16340 batteries, some devices will not be able to handle the extra voltage. Always follow the manufacturer's recommendations to avoid frying your flashlight with too high a voltage.

4. How many watts does A 18650 battery put out?
A single 18650 cell is 10 watt hours. You can draw 10 watts from one for 1 hour or 2 watts for two hours.
