What voltage should a lithium battery have?

Don’t allow the battery voltage to drop below 3.0V as it can damage the battery Lithium batteries will often have a specified maximum discharge current of say 2C, which means 2x their mAh rating. For example a 120mAh battery with a 2C max discharge current would only allow you to draw up to 240mA continuous operating current.

What is a constant current discharge of a lithium ion battery?

Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.

What are the key functions of a lithium ion battery?

The key functions include over-current (include short circuit) protection, over-charge protection (limit the max voltage to about 4.25V), and over-discharge (limit the min voltage to about 3.0V) protection. Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often.

What is a lithium ion battery?

Li-ion batteries are lighter than other equivalent secondary batteries—often much lighter. The energy is stored through the movement of lithium ions. Lithium has the third smallest atomic mass of all the elements giving the battery a substantial saving in weight compared to batteries using much heavier metals.

What happens when a lithium ion battery discharges?

When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.

Does a large battery have more current than a smaller battery?

In essence a large battery has greater capacity than a smaller one of the same voltage and hence may be considered as capable of greater current capability. As to maximum current, it all depends on chemistry, how long you want to draw current, how much money you have to spend, etc.
