I've recently gotten involved with RACES here with one of the clubs; passed the required IS-xxx classes, did the background paperwork and now just waiting to go in for prints.
My particular incentive was to operate events; a marathon, bikeathon, etc. So I did a bit of an experiment yesterday, let me know what you think.

Looks good Dan! I have a very similar setup using the same color CamelBak Talon instead with my FT-60 HT.

Found this online.
Seems like a great primer for volunteering at an event. The Boston Marathon guys have put a lot of stuff out there (including some bombing AARs). http://www.mmra.org/marc/Boston%20Marathon%20Survival%20Guide.pdf |

Very nice! I've actually been researching this exact thing (HT Go Bag) for the last few days while at work! Its nice to see someone who has a kit that has more than "snacks, water, medication" listed as their kit!

Looks good! I would still throw in a charger or maybe another extra battery.
Where's the best place to get that Camelbak model? I really like the flat bladder. |

I'm going to toss in a couple of lithium AA packs in there as well. Very nice having the AA snap-on-back. The bladders can be purchased separately http://shop.camelbak.com/Military-Tactical/accessories/reservoirs/l/710. I have the 100oz Short. (my MULE came with the typical long/round) The MULE itself was bought from some random site at the time. I found it through a google search and took a chance. 
I believe this is a 2011 model (they changed a little in features thru the years). |

Here is a cool video demonstrating a ham club operating an event (Boston Marathon again. 2012)

This would give you plenty of power, and be able to not only power your radio but anyone else that might need it.
I like the idea and execution. |

I would say two is one. Have two of the same HT radio programmed the same.
Locally race support communications are stationed at the medical aid locations we carry our own boo-boo kits but the course medics are there for medical response. |

I was thinking of starting a thread about the next level up of HT.
But having two UV2D models, which can use all the accessories I already have, would probably be ideal. |

Ok, going back to the big battery concept:
what battery would give me four times the standard 1700mah run time? Something light that will fit in the main pocket without taking up all the space. I can run the 12V accessory back cable from within that pocket, up the shoulder strap and into the HT. Potential caveat: the 12v back accessory provides 8.2V to the radio. So I figure anything that supplies more, like a 9.6V source, is fine. I tested it with a Radio Shack 8-AA holder using regular Duracells and it worked fine, providing 8.2V Naturally anything less than 13.2/13.8 would mean that the battery becomes HT specific ............ Something like this perhaps? http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9184 |

whats the acceptable voltage input of your radio? find a battery pack with a voltage inside that range and build a custom pigtail to go from the battery to the radio.

Something like this perhaps? http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9184 The battery I posted above will do all that. Use it to charge your extra batteries in your pack or use your car adapter and power poles. I wouldn't got with anything less than 12v. The cool thing about the battery I posted is the battery management that is built in. It requires no extra cell balancers, over/under voltage protection, and has built in fusing. Last week I ran mine down when it was hooked to my laptop. The battery read 1.3v. I thought I had toasted it. I read through the documentation and it talked about over discharging. I hooked it in parallel to another 12v and put it on the charger. It has been fine since. The other thing is weight. It is super light weight. That is true if you go the RC battery route too. My only thing is there isn't a easy way to charge an RC battery in the field. |

I figured, but it doesn't fit in the main pocket (along with everything else). It appears to be the same dimensions as the ubiquitous 7ah SLA.
Plus the A123 is expensiiiiiiiiiiiiive
I just did a search on lifepo4 and found this: http://www.batteryspace.com/custom-lfp-12-8v-5-0ah-battery-pack-with-20a-pcb-and-24-18awg-wire-6-0.aspx Just as many $$$$$$$$$ but should fit much better.
I think lifepo4 is much 'safer' than lipoly. ?? |

Expensive is relative. The battery you posted cost even more and has no management system. I like the cheap RC batteries but by the time you add the cost, complexity, and bulk of an external charger for one it rivals the A123 battery.
The A123 fits in my mule pack with room to spare. Plus it is also an investment for your 703....

That battery feels like an empty SLA battery. Like when you rip out all of the insides.

Here is a 12v, 5 AH battery. http://www.gruberpower.com/12-volt-4.5-4.6-5-amp-hour-ah-battery 20 That is an SLA. Look at the video above, when you apply a real world load to it the capacity drops to ~2.5Ah. Maybe less depending on the voltage range of your equipment. Plus that battery is twice as heavy. The price is hard to beat though. |
