Interesting stuff.

I was wondering about using NiMH batts.....4 or 5 of the 1.2V variety in series to produce 4.8V or 6V.

Any comments on this?

-- "Rechargeable (secondary) alkaline, nickel-cadmium (NiCd), and nickel-metal hydride (NiMH) batteries don't have enough output."

What's wrong with NiMH? I am currently using a homemade battery pack of 4 AAA rechargeables in series (4.8v) to a 901 atty. It puts out plenty of vape and will last me roughly 10-12 hours on one charge. Keeping 2 sets of 4 in rotation I never run out of juice.

That's exactly what I had in mind....or even 5 of them for 6 Volts.

True, 5 would make 6v, but pre-made battery holders for 4 which are about 1"x1"x2" are so quick and easy to work with. $2-$3 at Radioshack and and just hook up the two wires coming out the top, and find something to put it in. I used some 1 1/4" PVC fittings and mad-dog's tip on using a tire valve. The thing is huge, not quite as big as a coke can, but it stands upright which is convenient. Lots of room to work inside of it. BTW...the tire valves are an sae 5/16 x 32, and the atty's are an 8mm x .75...Soon as I can get a die I'm gonna try threading an RCA coupler. It looks just right for the 901 atty's and the in and out are already isolated.

Ok.... SOoooo has anyone tried using a LiPo cell from a microheli from like frys as a battery source after the dam thing flies into the wall a few times?

n/m they're probably unprotected.... plus hooking a current wasting solid on heating coil to it that doesn't pulse like a motor would probably frag half my face off.

ok found a good one....

check me on this.
