I posted a similar question today about what battery/charger to get. Here is a receiver pack im looking at:

Check the dimensions though to make sure the pack you get will fit.
And for charging them there are peak chargers and just simple over-night wall chargers..i think im going to go with the wall charger for the pack is the only thing i'll be charging.
