What is the iJoy 20700 Battery?

The iJoy 20700 has an incredibly large nominal capacity of 3000mAh, but the fun does not stop there as its most important feature is the 40amp discharge current. This battery can be both high-drain and high-capacity, making it the holy grail of batteries.

Please Note: The iJoy 20700 is a 20700 sized battery and therefore will not fit in any mods made to fit solely 18650 batteries. It is an ideal battery for mods that fit 20700 batteries, regulated and mechanical.
