The capacity of an 18650 battery refers to its charge storage capacity, usually in milliampere hours (mAh). If an 18650 battery has a capacity of 700mAh, then its charge storage capacity is 700 mah. This capacity is relatively small, but still usable.
3.5 can not be used, but the voltage of the 18650 lithium iron phosphate battery is 3.2V, and the voltage of the 18650 lithium battery is 3.7V, so the flashlight will be dark. Recommended not to use

Yes, but not less than 3.2V, empty the power, the battery light will shorten the capacity, heavy is scrapped
< br >
Yeah, it's just you need a booster plate a protection plate and things like that and it might be easier to choose one

No, the minimum content of 18650 battery should not be less than 27' V. Below 27V, it can no longer be used.

First, after the electricity is low, it can not bring the load, that is, shavers, flashlights, mixers, hand drills and so on.

Second, the voltage is too low, continue to use, easy to damage the battery, affecting the battery life. Whether it is from the use of reliable to economic is not a good deal, should be low power as soon as possible charge.

The suitability of the battery depends on what you are going to use it for. If you want to use it to power low-power devices such as flashlights and wireless microphones, then this battery is sufficient. But if you want to use it to power high-power devices, such as power tools, electric vehicles, etc., then this battery may not be enough, you need to use a high-capacity battery.

In addition, it should be noted that if the battery is used improperly or the battery is aging, the capacity of the battery may gradually decrease, resulting in a shorter use time. Therefore, it is recommended to test the battery before using it to ensure that it is fully charged.
