Edit: ended up tearing up an old 3.75v 1000mah nimh cell phone battery that consisted of three cells. Box works good now 
Hey everyone, I am not sure if this is the right section to ask my question or not but I am trying to build a battery box for my 510 since my auto battery bit the dust I figured I'd salvage the connector and toss something together.. I have lots of electronic components at my disposal as well as other miscellaneous things like battery packs from my RC helicopter (they are 10.8v 650mah nimh) my problem is that I am almost sure that 10.8v would kill my Atty so first I tried using an lm317 to drop the voltage down to 5v but I don't seem to be getting any current to my Atty and I know the Atty is still working since it fires up fine with my manual battery. I calculated resistor values etc to use with the lm317 to achieve 5v at 2amps but Atty doesn't fire when connected. There is power at the connector tho so I am puzzled.. I also tried using a 7805 regulator with no luck as I can't get more than 1 amp.. I have checked my wiring and all is correct so now I am wondering about just using some 1n4004 diodes to drop the 10.8 down to 5v but am concerned about too much heat from current draw. I am not sure if I have written a clear explanation or not so if more info is needed then let me know. Any thoughts/ideas/advice is greatly appreciated. Thank you
