Which kind of battery is good for cordless vacuum cleaner?
Cordless vacuum cleaners generally use power lithium-ion batteries, which are composed of several 18650 lithium-ion batteries in series and parallel to form a lithium-ion battery pack. The lithium-ion battery protection board has protection functions such as over-charge, over-discharge, over-current, and short circuit. Give full play to the safety and stability of the power lithium-ion battery pack. It can work continuously for up to 2040 minutes on a single charge.
