 Product Description:

It is very easy to use the cell in any circuit just solder the wires on the terminals or use 18650 battery holders to easily replace the used cells. Care must be taken while handling Li-ion batteries as they are volatile and inflammable and should not be handled roughly and punctured. Also, don’t overcharge and discharge beyond a certain point as gases accumulated inside might result in explosions and fire. So always use the Protection board while using Li-Ion cells.

C Rating: If you ever wondered what is the maximum amount of current that you can draw from a battery then your answer can be obtained from the C rating of the battery. The C rating of the battery again changes for each battery, let’s assume that the battery we have is a 2Ah battery with 3C rating. The value 3C means that the battery can output 3 times the rated Ah rating as its maximum current. In this case it can supply upto 7.8A (3*2.6 = 7.8) as the maximum current. Normally 18650 cells have a 1C rating only.

Maximum current drawn from battery = C Rating * Ah Rating
