9V 1350mAh LiFePO4: enough for UA-5?
« on: June 03, 2009, 05:02:42 AM »
Hi all,

I love my Wally world battery to my UA-5 for open taping, but I've been looking for smaller battery packs when going low-pro.

I found this LiFePO4 pack that looks interesting:

Does anyone know how much runtime 1350mAh translates to? If it's good enough for 3-4 hours, I'd jump on it, to save my back from the weight.

Still a bit expensive, but it's a new technology, I expect the prices to drop within a year. Maybe a third party manufacturer could pick it up and bundle it with a plastic enclosure, voltage tester and charger?!  ;D

Thanks for pointing me in the right direction, a good old Bri-post!
Although the link he mentions is broken.

So given Brian's form, this tiny sucker would only provide 2.4 hours of runtime with a UA-5. Hmmm  ???
And the other battery that I posted recently (1700mAh) is good for 3 hours. Workable, but not worth the risk running out of juice.

Back to the drawing board...

That link format was hooked to a prior forum version.  You found the meat but FWIW here's the link

As a rule of  thumb mAh can equate to the size of your gas tank.  The larger the full tank is the further you can go, all things considered.  Doesn't matter if you burn gas, propane or apples... the size of your fuel supply will ultimately control the amount of time that you can burn it. 

In most cases size matters and technologies are always making things smaller it seems.  Personally the Wally World LiOn format seems ideal.  Not having to lug SLA batteries around is a God send.
