Default 2000mAh Battery packs?

I've found a fellow that has some AA size Ni MH 2000mAh batteries, as well as some AAA Ni MH 700mAh batteries.

What kind of considerations should I be making before purchasing some for soldering into battery packs for my Tx and Rx?

What ratings do the chargers need to have to deal with this larger size battery?

thanks for any info....

Make sure they have tabs of course. A NiMH can be safely charged on a regular basis at 2C, and are safe to charge at up to 3C, just watch the temperature, they're more sensitive to it than NiCad's are. I'd suggest investing in a good charger that's specifically designed for NiMh's. Never EVER put a NiMH on a Nicad charger, ESPECIALLY on peak detect chargers, you'll toast batteries or start fires. If you don't intimately know the difference between NiMH's and NiCads, FIND OUT => There's plenty of docs on the net about it.

Yes I have agree- NiMH batteries are a different animal than NiCds. Since I first posted, I did a lot of searches and reading. I'm willing to do more...

This fellow has found NiMH batteries with the tabs. I'm seeing some pricing that is unit dependant- quite good pricing. I may suggest to this guy to monitor the for sale section. He can get some big NiCds with the tabs too.....

I might try doing up some packs after I find a good charger for them.

Thanks for the feedback

I just built up several NMH 2,000mil packs.
A 100 mil charger rated at 12-13 volts works great.
Takes appx 16 hours from dead to full charge.
I also found that 1,500 mil packs seem to last just about as long as the 2,000 packs and will go to a full charge in 13 hours @ 50 mil and 12 volt and 9 hours @100 mils 12 volts
