Lithium-Ion Rechargeable Battery Pack 7.4V 2500mAh Description
18650 battery it’s a lithium-ion cell its 18mm x 65mm size. A lithium-ion battery or Li-ion battery is a type of rechargeable battery. which is slightly larger than a AA battery. They’re used for Robotics applications, electronics, and electric vehicles and are growing in popularity for military and aerospace applications … For most lithium-ion cells, the lithium-oxide electrode is the positive electrode. devices due to their superior capacity and discharge rates. 18650 cells are usually rated at 3.6, 3.7, and sometimes 3.65 volts. These ratings are all essentially the same. It is the average voltage during a complete discharge. The complete voltage range most of 18650 is between 2.5 volts and 4.2 volts.
What are C rating and mAh of a battery?
the two most common terms you will come across is the mAh rating and the C rating. 18650 cell rated at 2500mAh means that when we consume 2.850A from the battery it will last for 1 hour and similarly if we consume only 0.285A from the battery it will last 10 hours so we can use the Ah rating to calculate how long your battery will last for your application based on the current consumed.
Crating for 18650 battery is usually 1C, this means that we can consume a maximum of 2.85A from the battery. This is because (Ah rating * C rating) gives us the maximum current that can be sucked out from the battery. For instance, if the C rating for our battery had been 0.5C then we only consume a maximum of 1.42A (2.8/2) from the battery.
