I asked about flat top / button tops in the Health Cabin thread.

Here's what was answered.
So now we don't know if the video is correct or the answer I was given. Or could a button top fit, but put increased pressure on the board when the spring compresses it?
I don't think the person at HC's is up to date on batteries. He might be thinking all buttontops are the protected ones that are longer. That being said another site said 18650's wouldn't fit and only stacked 18350's would work. I know many of the suppliers I deal with don't know much about PV's and batteries in particular. We probably won't know until someone on ecf gets one in their hand. I will probably be using mine mostly in the mini mode and use just one 18350 battery so I can have a VW pv I can stick in my pocket. 35.00 shipped for a VW is just too cheap for me to pass up even though I certainly don't need one. lol
