I'm looking to get a few new batteries for my Traxxax EZ-Start wand. The book says I can use NIMH or NICDS just as long as they are 7.2 volts. What is the differance between the two? I have a .26max on one of my Revos and some times its a little hard to start. The batteries always need to be fully charged to spin it fast enough and they die quickly. I wanted to get some thing with alot of power. Can someone please explain the difference between the two types of batteries. Thank You. (I did do a serch)

Really to be honest I dont know the diffrence.. Get something with a higher mah (capacity) something around 3300mah...

Go for a Ni-MH battery. They are easier to charge as they don't have a 'memory' and they usally have a higher capacity than Ni-Cad so they shouldn't run down as fast.

More info I got off a site...

Ni-Cad

Ni-Cads are the lowest cost option when purchasing rechargable batteries, they also have the lowest energy density i.e. hold the least charge when compared to equivalent batteries of different chemistrys. NiCads suffer from memory effect i.e. they should be completely discharged before recharging. They are available in all the common consumer sizes as well as specialised industrial sizes and packs. They are comparatively slow at charging and not considered enivronmentally freindly due to thier Cadmium metal content.

Ni-MH

Ni-MH are the more expensive than NiCad but cheaper than Li-Ions. They have superseeded NiCads as the consumer rechargable of choice as they have many advantages. They have a higher energy density giving them much more power delivery, they can be charged very quickly they are less harmful on the environment, they do not suffer from memory effect. They are available in the same sizes and shapes as NiCad.
Li-Ion

Thanks for the help guys. Don't you have to keep a 50% charge on the NIMH battries when you store them? I know I wont keep up with that over the winter and come spring time I don't want to find my bateries have gone bad.

Then you had better find an alternative to batteries.
EVERY battery made now needs to have a charge left in (and maintained) for storage. If you let any battery set flat for an extended period of time you risk it being ruined.
