I am using a Futaba T7CHP with the standard NT8S600B Ni-Cd battery (square brick type) but am fed up with recharging once a week for 18 hours. I see lots of alternatives in both Ni-MH and Li-Po but am wondering what the most cost effective solution is when you add in a charger?

I see on Ebay that I could get a 2500mAh Li-Po pretty cheap, but it is a 7s battery so I would have no charger. I have also seen up to 2700mAh Ni-MH batteries available, could I use the standard Futaba charger with this (say Ni-Cd only on the case)?

Thanks for any advice.

Hangtimes sells good stuff. I had a 7C and used one of their 1650 mAh NiMH packs. It came ready to go with the servo connector installed. Time between charges increased proportionally to the mAh rating. Although it takes awhile you can charge it with the stock wallwart charger. Capacity higher than 1650 mAh and you'll probably need a higher capacity charger.

easiest solution would be to buy a cheap quick charger.

if you look at a 7S lipo thats 25.9v versus 9.6v that the transmitter needs.

Thanks guys, went for a Hangtime 1650 Ni-MH and one of their wall-wart chargers for now.
