4 AW 14500's in a parallel circuit, What Could I run?

[ScubaSnyder]

I have a cheap light I got off ebay and it takes 4xAA's. I was thinking of running 3-4 P4 emitters, only problem is that the head of the light could easily fit 5-6 diodes with reflectors. The body might be able to fit 2xC cells with some spacers. If anyone is interested in helping, PM me, I can send pics of the light.

Ill post some pictures this weekend I have a busy schedule until then thanks jenova

Short answer: 1s4p x 14500 could run anything that will work on 3.7V - 4.2V and won't draw more than 5A. For 2s2p, up to 8.4V, 2.5A.

I don't quite understand how something that takes 4x 14500 (AA-size) cells could accommodate 2x 'C' cells. As jenova says, pics would be useful.

Bump, Pictures added!!

Do you own a set of vernier calipers?
Is so can you please measure the battery space

Also does the head come apart ?
If you wanting to run LED's, you might need to make a custom heastsink
(not the hardest thing)

Thanks

From the pic of the battery holder it looks like your batteries are in series not parallel. Are you getting 4.8V o r 1.2V with NiMH?
That is 14.4V nominal or 16.8V max with 4x14500. You will need to wire 4 emitters in series or one 4 die Osram Ostar.

I remember there was a there was a thread with someone fitting 3 or 4 P60 type drop-ins in a similar light.

Batteries could be placed 2 series 2 sets of series in parallel. -==-

The depth of the head is 1 1/4 until it starts to decrease, the batteries are in a series, I thoght they were series in parallel since it was a cheap light. The heads diameter is about 3" inches, a little less actually. As for the P60, That might be a possibility but Im not sure the light has enough depth to it. The body can hold 1 D Cell battery thats about it, I was planning on just keeping the 4 Aw cells in series as a power source.
