hi. i have an fr2le, would like to use my 7.2 r/c battery. manual calls for a tamiya 7.2 battery. does it have to be that specific or can any 7.2 work without harming my deck? does the mah matter? manual dont give that info, any help would be great. thank,  peace

Any 7.2V RC battery with a Tamiya-style connector will do.  The more mah, the longer it will run, but it's not critical - pretty much any RC battery in decent shape will easily power the FR2LE for the full duration of a typical show, and then some.

my 3600mah will power it for about 6hrs - fwiw

also, i learned the hard way, don't leave the bagttery plugged in if its anywhere close to dead
if it dies it will not charge again and you need to get a new one

Batteries can sometimes be brought back to life if you can force some charge into them.  I use a cheap car battery charger to initially give a little bit of charge to the NiMH battery I use in my FR2LE.  I only need to do this if I haven't used the battery in a long time.

With my charger, this takes care of the problem of the initial low voltage.  If the initial voltage is close to zero, my "smart" charger will refuse to start the charge.

Hope you can save your battery.

I bought giant batteries so I'd only use 65% of the charge and have it at "storage" capacity when I finished the average show. That way I didn't run it too far and kill the battery.

I hate dealing with those batteries and the fact that the run down to nothing if you leave them in the FR2-LE for around 2 weeks. One of several reasons I'm in the minority and never liked my FR2-LE at all.

Not exactly the type that goes in the 2LE but it gives you an idea that they can be zapped and be brought back.
