connect them and measure the voltage at the other end...you should be good to go...it when you start connecting batterys in parallel that you get into doubling the voltage...which might not be a good idea.

I use a 2400mah 4.8 pack on my Predator...works a treat...usage comes down to about 50 mah per minute of flying...going by the mah that gets charged back in...but this is with digital servos all round.

You might want to take a look at the Nimh 3700 mah packs you can get...I got one late last year...still havent fitted it yet. Might be looking at fitting a generator...this is going to fit onto the starter shaft...I use the pull start anyhow. The only 'mod' I have to do is to take the starter bearing and put it upside down...so the shaft is driven...thus powering the generator.
