Built In Battery Mods
All of the mods featured in this section have built in batteries that are non-removable. This means that when the battery does eventually die, you will need to replace the entire mod. With that said, mods with built in batteries are often a bit cheaper and offer extra peace of mind knowing the battery is always stored safely within the device.
Most Lithium-Ion batteries should take around 300 recharges before showing signs of degradation.
