Hot dogs and beer

[bownsy]

I like hot dogs, I like beer, I do not like using alkaline batteries for my receiver. I have read of people using 5 cell nimh battery packs but the operating range of my servos are 4.8 to 6 volts, while the nominal voltage of the 5 cell nimh is 6, fully charged dont they reach 7+ volts? would that be hard on the servos? I was thinking of using a 4 cell nimh, but have not found anybody using those. Do they not stay above 4.8v long enough to be worth it? The ones I found say aircraft use, but I dont think that matters a while lot. Any thoughts?

The extra volt fully charged is completely within the tolerances of hobby servos. Running 6V servos on 5 cell nimhs is just about standard practice for nitro use. "6V" servos are fine on up to 7V, I've seen 7.5V as a hard limit before things blow out in the control board.

I've used a 4-cell nimh, it works fine too, just a tad slower and less stall torque. There's one here, out of stock at the moment but they get them back in occasionally. I've even used 4-cell NiZn, which had a fully charged resting voltage of about 7.2 volts and ran fine.

@tudordewolf thank you, If the 5-cell fits I will do that but $7 for that 4 seems pretty good.
