What we have here is a group of highly trained professionals. All spot on guys. This is the benefit of the Zion's power plant... An easily obtainable, well tested and economical replaceable cell
So I dare ask, when I do the single cell unit should I hard solder the battery in to cut cost or should I make it replaceable... Seems like the portable vape companies are using both models... What do folks prefer?
Edit: furthermore if it's rechargeable via a micro USB would you still want to AC charge spares? How important is pass through if the battery is swappable?
...and what if you could make a vape super stealth but the battery life was measured in hits? What if that vape had a three second change-out of both the battery and the load? Would that make a 10 hit battery life tolerable? Where is the size / energy battle balance out?
