I may be wrong but I remember reading somewhere that the 510 battery contains a AAAA size lithium but not 100% sure. Either way unless you enlarge its capacity while keeping it small there is not alternative other than either a longer battery or going to a
mod.
There are tons of different
mods out there as you have probably read about and some I think are way overpriced, but for the technically challenged it may be their only way to get one. If you have a little tinkering ability, some simple tools and patience, you can make your own NicoStick for less than about $25.00 in parts. The instructions and parts lists are posted and I built one myself and enjoy a minimum of 8 hours of good
vaping per battery.
And if you need any help, there's plenty available.
