Features

01

LARGE CAPACITY: The capacity of 18650 lithium battery is generally between 1800mah and 2600mah.
02

LONG SERVICE LIFE: The cycle life can reach more than 500 times in normal use. which is more than twice that of ordinary batteries.
03

HIGH SAFETY PERFORMANCE: The positive and negative electrodes are separated, which can efectively prevent the short circuit of the battery.
04

NO MEMORY EFFECT: it is not necessary to empty the remaining power before charging, which is conve- nient to use.
05

SMALL INTERNAL RESISTANCE: The internal resistance of polymer cells is smaller than that of general liquid cells, and the internal resistance of domestic polymer cells can even be below 35mΩ.
