I've been loving my MVP's but I am a little concerned about the battery they use.Do you happen to know?
I stick with the AW IMR's too. I do need to get a few flat tops, so I'm going to have to look into those.
Basically, I stay away from LiIon (lithium ion) totally. These are the ones that will erupt with fire if there's a problem. AW IMR's ( I think they are LiMn) will still vent if shorted, but will release gas not flame. The first thing I check for is what the battery is made from.
For ecigs, we need "high drain" batteries. They are made a bit tougher to handle the extreme demands that vaping requires. Using non high drain will overburden the battery, making it heat up and more prone to failure.
I haven't really checked into the Panasonics or Efests, but I know a lot of people are using them. That doesn't necessarily mean they are safe. If they are LiIon and have a protection circuit, they are safer than if they didn't.
One main thing I got from quick reading - DON'T leave them in your hot car!
the good news is I now have an umbrella.
