ALL Batteries can explode if used improperly or in the wrong devices (which is, after all, still "used improperly"). Neither lifepo4 or NiMH batteries are made for vaping, can't handle the high amps required for today's vaping power requirements, nor have the required voltages.
There are no commercial vape products made for those batteries.
You are however free to make your own choices and if you want to design and use a device using those batteries, have at it. You will need to collect some higher ohm cartomizers (like 2.5 or 3 ohm resistance or higher) in order to even come close to being some what safe. But please warn people around you before you try vaping on them, so that they can move away from you and a potential explosion.
