But you would get more bang for your buck buying NiMH packs from these guys.

Your existing wallwart charger will do the job. I would plug it into one of these cheap time switches
http://www.walmart.com/ip/Woods-5000...50000/21682990 set it to charge for 3/4 hour every day. When you come in from flying plug both the RX and TX batteries in and set the overide on the timer to charge for enough time to fully charge the batteries, say 5 hrs for a short flying session 10 hrs for a long one. Leave the timer charger and batteries plugged in and every day they get topped right back up. NiMH do self discharge more than most other batteries.
