Are 21700 batteries worth it?
Ok, they are great in one area - price. 21700's are cheaper in relation to capacity. 21700 also simplifies building of battery packs, as for 1800 Wh battery you need to assemble 96 cells, while to build the same pack using 18650 you have to use 140 cells. More welding, more materials etc.
What are some common uses of 21700 batteries?
21700 battery is one of the most popular and commonly found cells in the battery pack in electric vehicles, battery-powered construction equipment, portable power cutting/drilling tools, the emergency torch, flashlight, etc. after 18650 battery cells.
Which type of 21700 battery should I choose?
We absolutely recommend protected 21700 batteries. Protected batteries generally have a button top, while unprotected ones typically have a flat top. The average 21700 battery charge time is about 4 hours, which can vary based on the charger and battery type.
What is the voltage of a 21700 cell?
A 21700 battery, or a “21700 cell”, has a voltage of 3.7v. It is a high capacity lithium ion rechargeable battery with between 3000 mAh and 5100 mAh (mili-amp-hours).
Why are protected 21700 batteries recommended?
Protected 21700 batteries are recommended because they have a “button top” and are safer for use. Unprotected batteries should only be used where the load/draw and charging is externally monitored and controlled. Unprotected 21700 batteries are cheaper, but we do not recommend their use.
Are unprotected 21700 batteries less expensive?
While unprotected 21700 batteries are cheaper, we strongly advise against their use due to safety concerns. Unprotected batteries should only be used where the load/draw and charging is externally monitored and controlled.
