Mag mod power sources ???

As some of you may have seen i have modified my Maglite to run an SST-50, I now need to look at an alternate power source as the trustfire 18650 cells only last a few mins before the protection circuits kick in.

 

So what would be the best alternative AM IMR cells over here they cost £10 each

Or 6AA adaptor which are around $24 and i have enough AA to run it.

 

Thanks for your input..

Or Kaidomain's 32600 cells. About $34 for two.

I have two of these to run an ROP. 

 


Warning, they are unprotected flat-top cells and need magnets to make contact. And they are longer than a D cell so it's best to get a shorter Mag spring or hit the existing one with a grinder till it is a good bit shorter.

But KD is out of them and I've no idea if they are getting any more of them made.

 

You'll only get about the same runtime out of 6AAs as you do with 18650s and the holders are horribly overpriced IMO. Bung the light engine in a 6D and get some of Maplin's 8,000mAh LSD Ds (Which they might have on clearance) for good runtime. That should give you around an hour.

 

But nobody has ever accused a 6D of being portable.

 

The numbers from my light tests are always to be found here.

HobbyKing can help there and I can make up balancing leads for you...

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7028

I have one of these and it is cheaper than the identical DX $43.50 one.

You'll also need a 12V power supply - an old AT power supply out of a PC will do fine here and is usually free.

I've had mine for three years now. No trouble, but I do keep an eye on voltages. Sometimes.

 

I just use it till it dims, then charge them. I do check the voltages when I take the cells out and when I've charged them.

 

I have charged them on a small charger, it just takes a very long time. I made an adapter out of wooden dowel with screws in each end and leads with magnets to hold the Ds.

Not pretty, but it works

Not pretty, but it works.

 

I really wouldn't want to short those cells though...

Could i use my Ultrafire WF-139 to charge them ? what sort of time would we be talking about to fully re-charge two cells

8-10 hours depending on how far they are discharged. I'd keep a close eye on the voltages though, just to be on the safe side - those things hold quite a lot of energy.

 

That is what I built that rather ugly adapter for. I have another one somewhere.

Remember you need a 12V PSU as well. An old AT power supply from a PC is very good quality and usually nearly free.

 

It doesn't come with a manual but I can scan the DX one and put it up - all of these are imax B6 clones and work just the same.

 

The manual can be found here but it doesn't give the pinout for the balance connectors.

I'll scan the appropriate bit from the DX manual and put it up.
