Ok, I have a Mag 2D ROP and I am using Kaidomains 3AA to 1D adapters with 2700 mah Titanium NiMH. This is about the fourth charge with no problems but this time when I went to charge the batts it slid out in one piece! The two ends melted together but the batteries seem to function just fine, they even slide in and out just like normal. Is there any danger here? And what would be a possible cause to this as the first four cycles went perfectly? Should I stop using the light right away?

Thanks guys, I'm still learning.
 
I think I may have found the culprit...I noticed that one of the batts had the plastic outer sleeve work away on the top ridge that went about 1/3 around the top, could this have caused the heat for the melting? Anyone know?
 
i think you might be better of using 2 Li-on D cells then those adaptors.Sorry i cant help more. If you want good battery adaptors, go for fivemega's

With a proper adapter, your ROP High would be ~40% brighter, and much whiter. The Kai one was never made to handle the current of your ROP, and they are very well known for melting.
 
Will there be any difference in brightness/resistance between mdocod and fivemega holders?
 
As has been pointed out, those inexpensive adapters are not suitable for this use. The contacts are poor and their high resistance will cause heat buildup and very likely a severe meltdown.

This problem occurs not only when charging, but even more when using your light. Your total output and output quality will be greatly reduced.

Buy some good adapters and you will see your ROP in a whole new light!

The 'fivemega' adapter is held in the highest regard, mainly due to excellent construction and the handy charging port.

The 'mdocod' adapter will be just as bright as the 'fivemega' adapter. It is not finished as nicely, and does not have the charging plug, however, it is roughly half the price, and still very solid.

Probably the BEST option though is to buy a NiMH pack from LuxLuthor. These are made from either Elite 1700 cells (brightest) or Sanyo Eneloops (most useful), and are WELDED together, leading to ridiculously low internal resistance of the pack. It comes with charging magnets, which you must connect to a pack charger to charge.

I was already going to purchase one of LuxLuthor's packs for a different light so I might just go ahead buy another for the ROP. Thanks for the suggestions guys.

That might have been caused by the heat itself... sort of like a symptom but not the actual cause :(

The fivemega holders are incredible... years and years from now, with whatever new rechargeable AA cells we will have then, the fivemega holders will be still good. No obsolescence with AA cells. The welded pack will eventually sort of... well... die... and you won't be able to just change the AA's like with a fivemega pack. With a fivemega pack you can crack it open and test each cell and replace as necessary etc., Just some stuff to think about.

Yeah that makes sense too. Hmmm, I don't know what I'll do know. That battery with the exposed metal still charged fine, should I toss it or still use it?
 
Oh i hate those Sanyo 2700s, the wrapping is so fragile and thin. Overtime even a moderate heat and friction will eventually thorn it appart. I had 3 accident involving those cells.
 
Wasn't there a resistance fix for the KD adapters? I can't find a link for it but if someone has better luck can you post it? This thread makes me want to check it out again.

Yeah, it was called the "allburger"where you apply thin copper under the springs and bottom contacts. But people say that the ROP is supposed to be bright and white, I only had bright and yellowish but never white with this fix. I tried it and it did seem a little brighter though.

Well that answers what I was thinking...What batts did you switch over too instead?
