is there a battery pack that is compatible with the avalanche? mostly out of curioscity plus i think it will save money in the long run

any 5 cell hump pack will fit.

but there is only 4 aa's in there. wont that be too much juice

regular alkaline are 1.5 volts each, rechargables are 1.2
1.5 x 4 = 6
1.2 x 5 = 6

same voltage, just more batteries

is it difficult to swap the packs

no, just unplug the 4 pack holder and plug in the hump pack.

which hump pack would you recommend?

it really depends on your budget but the more mah the more output and longer it would last

this is a real nice battery: http://www.clermontmotorsports.com/s...Pack-Rx/Detail

You will need an adapter or a new switch, the avalanche has the 2 pin receptical for a AA battery holder not a hump pack which has a male three pin.

you just trim off a little off the plug on the hump pack to fit the 2 pin connector, the 3rd pin on the plug has nothing in it.
