I am planning to purchase a small electric helicoper from a friend for $25. The only problem is that the 6 cell nicds are probably no good anymore. I was wondering if it would be possible to use a 2s lipo instead of the stock battery. With Lipo, the voltage would be 7.4v which would be a .2v increase over the stock battery. Do you think that this could be a possibility without frying the esc?
Sorry if this isn't the correct place to post, because this is my first time posting in the heli forum.

Thanks,

Most likely you should be ok. The voltage increase is actually different than you might think it is. 7.2 and 7.4v are the nominal voltages, the actual full charged voltages are really close to the same. 1.4v per cell for NiMH is probably about what you would take it off of the charger at, and the full charged lipo will run 8.4v. That should be exactly the same =) You should be good to go.

Usually escs are rated quite a bit higher than what the pack voltage is, like the parts in my esc are rated 15v to 30v and mine has a 3s lipo, which is 11.1v nominal and 12.6v full charged.

Hey thanks for the quick reply mrasmm. Sounds like this thing will be flying on Lipos then. Thats cool that the charged voltages are the same, I didn't know that.

yup, no prob =)
