1. 18650 parameters:

The size of 18650 battery is 18mm in diameter, 65mm in height, and its capacity ranges from 1200MAH to 2800MAH. It has 1C-5C current discharge, small internal resistance, light weight, stable performance, sufficient capacity, long cycle life and many other excellent performances. The nominal voltage of a single cell is generally: 3.7V. The charging voltage is generally: 4.20V. The minimum discharge termination voltage is generally 2.75V. Lower than this voltage will easily lead to a serious drop in battery capacity or even scrapping. The maximum charge termination voltage is 4.20V.

2. About combination and should field:

It can be used alone or combined according to customer requirements (such as two combinations of 7.4V, 11.4V, 14.8V, etc.), especially suitable for notebooks, flashlights, MID, MP5, mobile DVD, video cameras, projectors, mobile backup power , lighting fixtures, LED products, communication power supplies and other high-tech digital products.

3. About the protection circuit:

In order to adapt to more product matching, ensure that the entire battery looks better, and the battery is more resistant to drops, we have a variety of solutions to equip protection plates. The close cooperation between the protection board and the battery effectively ensures that the electronic components on the protection board will not be squeezed by the battery when the battery is dropped. Specially equipped with pointed 18650 batteries for lamp users.

4. Regarding delivery:

Punctual delivery, quality assurance, if the customer is a combination of more than one, the company will provide free matching.
