I use a
Flat Top Adapter and not magnets. basically just a round piece of Plexiglas with a rivet in the center. It's like a nipple implant. That's how I use a 35 amp flat top in the futura. Otherwise stuck with low amp nipple top batteries that can't keep it up once their voltage drops to 3.9 volts when vaping at 30 watts. Would probably be cheaper to make, go to the hobby shop and get some silver rivets and use an old credit card to cut and cut a battery size disc, insert rivet, flatten with hammer, BAM, you have a nipple. Titillating isn't it. lmao
