This is a very interesting trend, do you think that integrated batteries are going to take over the market?
It takes the Expense of batteries and Chargers out of the picture. Also it allows the manufacturer to control the battery equation and avoid damage to Pv circuit boards due to inferior quality batteries.
The Stainless MVP has it's place. Me I prefer smaller form factor of the Ivape MVP and the more elegant look.. I also am vaping in the average range.
But I can see that the MVP has it's place too.
I don't think they will take over, although a majority of the midrange PV's have them I think it will remain a balance of both types of batteries.
