I'm thinking I might just try to file the nub down till there's nothing but the head left. Then find a disc that's flatter and attach the head of the nub to that. I really want an adapter damn it! :D

Could just buy a Woodvil or resin and make it n easier on yourself and forget the adapter.

ed, right after I last posted I sanded it down with my dremel. I had to use super glue to attach the head to one side because the lip got sanded off the other side. It's just the head flat against the disk on the upper firing pin side and on the other side is a very short leftover of what was the post. It still compresses the spring more than I like but it's no longer going up into the firing pin opening and it works. There's no way to make it not compress the spring because the disk is to thick even though the disk is already pretty thin.

I'm the type who likes to tinker when something peaks my interest and I can't stand being told I can't do something I want to do. So this adapter never stood a chance, it told me no. :D

That works.. magnet did not want to move while inserting the battery which was good and did not move either while sliding the door on.. I was thinking maybe the magnet in the door would attract the other but no.

Springs good as well using samsung whatever 5 rare 30amp flat top battery.

Oh and 0 arching (1ohm coil) as I checked in the dark!

Edit.. and yes I re wrap the battery as I wouldn't see green on my black sl reo hehe

Great idea Steam. Looks great! Have you noticed a voltage drop by adding the earth magnet directly on top of the battery like that?
sorry.gif
I'm thinking that current traveling through a magnet like that might affect voltage. I"m wondering if just a plain piece of copper might work better.

...Better yet, AW might look into creating a button top 3000mah if more people contacted them about why it's needed. One could say... "Hey man, We're Reo Grand users. That sums it up. 'Nuff said.

If I could slap the grand on the coilmast 521 id test it but the button is in the way of it fitting. I could use an adapter but then i'd be adding something else to the loop. Could just try adding prongs from my DMM to the posts of the atty to get a reading. Wont get a chance to do that till tomorrow. (EDIT I can and have done a test reading with the woodvil on the 521 heh

I wouldn't doubt it adds something to it.

AW just rewaps other manufacturers batteries so no idea if they can a batt made with button top till someone else does.

Interesting steam, thanks for sharing the magnet pics. If I can't get used to the button throw of this flat top I'll give that a try cause I don't like how the disk adds more height all the way around. The adapter is a great idea but definitely needs some revision for Reo's. So far the button throw isn't to bad. Now to see how long these 3000's will last me.

It's that time again, time to order new batteries and while I was browsing RTD I noticed an interesting little gadget called ^^this^^. I'm going to purchase some of the AW 20A 3000mAh's for their longevity, I'm always in the 8-12 amp range, and I think I'll order one of these little doo-dads too and see how it fits. I use Noalox and I guess I'll apply it both underneath and on the nub of the adapter. I wanted to mention this little thing here in case anyone else who's a staunch button top user but wants to try flat tops for higher amperage or mAh but doesn't want to have to adapt to a longer button throw. Can anyone think of any reason why this could be a bad idea outside of the length it would add?

I ordered one and it works well. I just prefer the button top so do not use it or the flats.

Tested the batts with and without a few mins ago on the coil master 521 tab.

I even managed to get a metal reo grand on there for the test.

Could post numbers with and without magnet but it all did not matter one bit!!! Why?? Cause the reading was the same with or without the reo tiny magnet!! I'm shocked.

I even tested it with the adjustable 510 extended and retracted all the way.. it was the same!

I was also shocked to find that the load drop on the metal reo and the woodvil was like the same!

Load voltages of 3.82v was what I seen with fresh 4.2v batts and .9ohm coil.

I even made sure I over cleaned all contacts prior with white eraser and runing alcohol and deoxit gold applied.

So.. if you want flat top batts on your metal reos think about ordering a reo door magnet at. 50 cents ea! Haha

Note.. pic was taken after test! Hense why the cap is removed and 0 wick as I needed to I stall a new wick after burning up that one! The tab is no bottom feeder! Haha forgot to drip till after burning it up.

With testing on the 521 tab make sure the adapter is on real tight of your numbers will be low. Might need to extend the adjustable screw on the 510 adapter to get it on perfect.

Just now did more testing on both a Woodvil and reo grand and the same results with or without a magnet on the battery this time using a dmm with prongs connected to the negative and positive posts of the atty.

3.88v on load with magnet.. also it seemed even better with the magnet. A whole .01-.02 higher with the magnet and no dancing around. Maybe the magnet gives the battery a more solid flat surface for contact other then my sanded top from past repairs from pitting.

Also tried the magnet still on the battery on the battery charger and 0 problems there as well.. on a 4 batt charger the magnet held in place and didn't budge to fly off.

So sounds like a seriously doable adapter to me.. slap a magnet on and forget about it.

Other testing needed would be real low ohms like .2-.5.

Dare I be the one to try it at lower ohms? I so badly want to switch full time to flat tops...so, a door magnet on the positive contact, you say?

:glug:

Go for it! Haha.. though I could try some crazy low ohm atty either late to ight or tomorrow.. just sucks to reck a good build on them now.

Found a few websites that offers flat top magnet extensions. Sooooo, it's apparently OK to use a magnet on top of a Flat Top battery with NO problems. Shocked!

Always thought magnets would be a no no.

Would like to see more test results though. For instance, how it charges with the magnet on it, etc. Other than that, ...it looks like SteamStack single-handily solved an irritating problem for us, and opened a bridge to another world of using flat tops with our Reo Grands. Way to go Stack!

I ordered some magnets last night...turns out to my great surprise, magnets are something I overlooked when getting backup supplies. Will try them with a .3 build when they arrive. My concern with flat tops was never button throw, but the pitting and arcing, which seems rampant anytime I use flat tops in metal grands. If this fixes that, I'm gonna be one heck of a happy sloth :)

I use magnets in another mod to shorten the button throw, so I've been using magnets in mech mods for a bit now. Definitely no danger in it, from what I've seen.
