Is my dream ego type battery even possible?

[Shizzle]

if a company were to make a fixed (NON-vv), 4.0 volt ego type battery with 1300mAh power, would it be about the same length as one of those newer, compact, standard 1300mAh ego batteries?

the reason i ask is that although i love my vision spinner, i dislike the length, and i only ever use 4.0 volts anyway (as do many others i've come across on here).

thanks to any engineering minds that can shed some light on the subject for this clueless dreamer.

a fully charged 18650 will put out 4.20v. most non-vv ego's are regulated at 3.7v.

I hear you. I have a twist and it most allways is set on the same voltage any ways. I Have eGo 2 Upgrades. Same difference. I run at about 4.3 ish? Idk. That is all I need.

Most of the standard eGo units are (were?) modulated to 3.4 volts. Some are 3.7 particularly the eGo-like units (Riva etc.).

This is because Li-Ion batteries are 3.7 volt batteries (the 4.2 volts is just the "full" charge but it drops off quickly to 3.6/3.7 volts and stays around there for most of the duration).

Anyway, going ABOVE 3.7 takes more circuitry...a booster. Adding VV takes a knob/dial too. But even without VV, you'd need extra room. Or use two batteries stacked and then modulate it back down. Either way...longer PV.

DANG...but thanks for the info!

If you build your own coils, you can get pretty close to what you want. Don't change battery voltage, get your coil resistance where you like it for what your fixed battery is regulated to and you can vape away. When battery voltage drops too much to get a good vape, swap to your spare battery and vape on.

What are you using on the battery? Most clearos are really easy to rebuild and there are plenty of how to's out there. Rebuilding a coil with thicker gauge kanthal will allow about the same number of wraps with less resistance. If you like 4 volts, you'll need a coil with slightly less resistance (but similar surface area) to vape about the same using, for example, 3.3 volts of a fixed battery.
