Energiser
We in Dubai use the new rechargeable batterry from Energizer. They are NiMH batteries. The ratings are AA @ 1750mAH and AAA @ 800mAH. We construct them ourselves and shrink wrap them.
Weve been using them for a while now and typically the charge in them lasts for about 10 flights of 15 mins with out a recharge.
Great value at about $14 a battery pack, and given the NiMh properties, no battery memory.
We use them in our Tx's and Rx's.
I will never turn back.
The AAA's are great as you can custoise them to fit snuggly into your fuse, due to there size.
