iJoy 21700 – 3750mah/40A

One of the worlds largest vaping companies have manufactured a powerful, reliable and high capacity flat-top 21700 battery for a variety of long-lasting vaping setups.

The iJoy 21700 has an incredibly large nominal capacity of 3750mAh, but the fun doesn’t 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 21700 is a 21700 sized battery and therefore will not fit in any mods made to fit solely 18650 batteries. That being said it is an ideal battery for mods that fit 21700 batteries, regulated and mechanical.
