19650 flat tops?Do they even exist?Anyway the 18650 work great on the grand!

You meant 18650, right?

You can use flat tops in a Reo. However: The switch will have a different feel to it because it requires longer travel to make contact with the battery. It may not work so great if you decide to use a button cap on the switch because the cap cuts down the length of the switch throw a bit.

Magnets are out of the question.

I use button tops and flat tops all with no issue on my grand.

The new S/O firing pins work especially well with flat top batteries

If using flat top bats with sub-ohm builds, you should prolly put some noalox on the firing pin lever and (according to the modmaster himself) on the top of the battery. This is even with the gold upgrade innards.

The issue some have reported is arc'ing between the firing lever and the battery top - the noalox is to counter this possibility.

I have 2 flattops and 1 button top and they both work splendidly in my grand. Enjoy............

I use Sony VTC5's all day every day with the SO contacts. If you do NOT have SO contacts (the gold ones), use AWR IMR 18650 1600Mah batteries.

I used Sony VTC4's with the old contacts and I actually broke a battery, somehow the flat top got indented and the firing pin would no longer make contact, this happened after 4 weeks of battery use and it was same as always for 1 hit and then the next it wouldn't fire. I took the battery out and it was very dented in.

Do not use a spacer or magnet!

Most of my AW IMR 18350s have ended up with dented bottoms. Some from one of my old chargers that had too strong of a spring and some from dropping my VVW. That prompted me to disassemble a few old dead batts (varius - mnke's, AW's etc) to see what I could see. The flat tops or bottoms on most batts are wafer thin and there is a gap in most of them between the cells and the top and/or bottom. The only thing in that gap is the conductive strip and a little solder... and that just on the edge, so it doesn't offer any structural support.
