I got a vamo v-5 in July and it has been a pc of junk! The center pin issue a week after i got it, o ring and tweezers fixed that. The batteries quit charging a month later bought new button top batteries. Then the cheap charger that came with it quit working so I bought a good charger. It did fine for a while then one night I started getting strange read outs on the LED..like low v and then like tiling on the screen but I had just put a new battery in. I tried changing the clearomizer (removed i clear 30s and put my nautilus on there) and still nothing. Changed to fresh battery...nothing. So basically I'm tired of fooling with it but I want the bigger mod vaping experience so I broke down and ordered a provari because I am already into it with the battery charger and (2) Efest 18650 3.7 volt 3400mah li-ion with PCB (button top) The charger is also the Efest with LED volt read out that my local vape shop said was better than what came in the starter kit. I did not order the whole kit from provari, just the unit and the extender cap and extended warranty. Can I use these batteries and charger for the provari? I don't want to mess up my new mod. I send a question to pro vapes but haven't heard back from them. My mod is scheduled to arrive monday Do I need to order different batteries because local shop is way too $$$ on them and can get online for a lot less.
