Which is better an 18650 battery or an unprotected battery?
18650 protected batteries have an electronic circuit. The circuit is embedded in the cell packaging (battery casing) that protects the cell from “over charge”, heat or “over discharge”, over current and short circuit. A 18650 protected battery is safer than an 18650 unprotected battery (less likely to overheat, burst or start on fire).
How big is an 18650 air conditioner battery?
A small air conditioning unit that can cool about 9000 BTU uses about 1100 watts per hour. So it would take more than 110 of the 18650 batteries to run the air conditioner for 1 hour. In comparison you would need three 12v 40 amp car batteries. But 110 18650s are smaller than three car batteries.
