Flat top batteries and magnets in a REO

I think the thing that most people are concerned with is the magnet moving around and coming in contact with the inside of the case (hard short).
It's not recommended because of the risk of causing a short if the magnet moves. But radio shack sell rare earth magnets for a few $ and they seem fine.

There are people who have soldered the magnet to the top of the batt (dholms), to prevent what Trunker mentioned. You have to be very carefull putting a hot soldering iron on a batt, this is not a recommended fix, very easy to damage the batt and yourself. I believe pdib created a custom firing pin out of brass to accommodate some of his flat tops. Either way it requires some heavy modding, and you've got to know what you're doing and have the right tools. Generally you want to avoid flat tops if possible.
Magnets and batteries not a good idea . I would just use your flat top batteries if that is all you have
Just measured a panny ncr18650b (flat) and an aw 1600imr (button) . Exactly the same. The protection takes up a little space. I don't use the pannies in my reo except in an emergency, but I have and they work fine. The aw just hits better in general on a .9 ohm build. I don't have any 30a Sony to measure, maybe someone else can speak to that.
I do it with the 30a 1600mah efests. The magnet is from light hound and it's strong enough that is doesn't move. I will also say that the wrapper on the battery prevents the magnet from sliding outside the center, only realize this when I try to remove the magnet to charge
I must confess I've been running the 30amp Sony's, the Samsung INR18650-20R 2000mAh, and the MNKE's with and without the magnet. The magnets (from Radio Shack) hold pretty strong and they don't move but my Grand's worked better for me without the magnet. I had some misfires using the magnet even though it didn't move.
That's just me - When I run sub Ω I want a battery that doesn't come close to breaking a sweat. I know the AW 1600's (24amp) are a better fit but I do like the 2000mAh Samsung's from KP - they last all day.
Like other folks have stated, if you go below .5Ω you will have problems with the firing pin sparking and quickly oxidizing. I have found that to be true. Hanging ~.8Ω now - much better.

I use a 2 cent safety fuse, it has a button top on it, or a vapesafe or a short stop do also.
