A couple of points to address real quick:

DON'T charge your eneloops at 2000ma (1C) with ANY charger. I have found the sweet spot to be 250-350 mah. They can be used in any xmitter (that I am aware of) in 8 cell series. As has been pointed out already, use a good computerized nimh charger. Stay away from wall-warts, most continue to charge even after the pack has finished charging.....this will destroy nimh batteries.

One final thought, please be very careful using these packs as receiver packs. Their discharge "C" rating is not very high and you may find yourself drawing more amps than these batteries can supply (especially in the larger birds with a high servo count). If it works for you, great, just BE CAREFUL!!!
