battery of choice for PHRs?

So, I am currently trying to decide which battery I am going to use to power a PHR running off a fixed driver at 120mA. As I am making my own host for this, I am not limited to the size of the host. I have been searching, and I see a LOT of battery related threads, most talking about which batteries will be best and still fit into a specific host.
The question, obviously, is if you had your choice of battery to power a phr module, and the size of the host was NOT an issue, what type would you go for? larger storage capacity? Smaller size for better portability? A good balance between the two? What kind of setup would you personally prefer in a rechargeable battery if you were casting your own host? and most importantly, Why?

(as a side note, I am casting my host out of sterling silver, so I am most likely going with a smaller more compact format, as it will weigh a lot if I make it too large, which increases rapidly my materials cost, as well as too heavy of a pointer would be pointless. I am mostly just curious as to what people would prefer and why)

I would probably go with CR123A's as i like the fact that they are light and provide 3V rather than just 1.5V from an alkaline source. What driver are you using, as that WILL be a determining factor in your battery choice.

True. The driver will be rkcstr's Fixed Micro-Drive. (buying the laser module from Mohrenberg. As those wonderful prices talked me out of buying the components seperately and assembling them myself)

For the rkcstr, you can use either 2 x 3.6v or 3 x 3.6v

If you use 2, you will have to recharge more often since the voltage will drop fast.

For 3, it will make a little extra heat. You may want to use a diode.

The best battery available to drive laser diodes is the #18650.
It is the most reliable and longest lasting.

I use it exclusively in all my hosts.

It is 4.2 VDC and would require a boost driver like Dr. Lava's.

Very useful info. Although I would assume stacking 2 of them for 8.4 volts would still suffice. read somewhere that the rkcstr driver for a phr needs 7.2-12 volts. (and several comments that 12 volts is too much, so closer to the minimum is desired apparently) thank you. this was exactly the type of info I was looking for :D
