I would really like to use the great planes because I have a triton charger and I hear that the balance plugs are diff on the thunder power batts.
I use [link=http://helihobby.com/html/lithium_batteries.html]11.1v 1350ma DN Power Li-Po's[/link] with an Equinox balancer and they work great. Here's a pic. One of the Li-Po's came with a polarity reversing harness so everything is just plug-n-play. Another option is [link=http://www.helidirect.com/product_info.php?cPath=31&products_id=1821]Mega Power 11.1v 1350ma Li-Po's[/link]. They look exactly the same as the DN's so they may be compatible as well.
