Re: (ET) Time for a NiMH Elec-trak - Amp hours

["John B Reinhard" <reinharj frontiernet net>]

Aren't our typical Trojan Golf cart batteries rated about 200 amp/hours ?
so our packs are 36v @ 200 amp/hours ?
Chris wants to try a pack that is 1/4 of that ?
am I understanding this correctly ?

Should be lots lighter anyway . . . if that is what you want
But in the case of a tractor, we are always talking about MORE weight over
the traction wheels, etc.

I wonder if these NMH batteries can take recharge like the Panasonic NMH
cordless drill packs - full recharge in under an hour !
What does that do to charge cycle life ?
What is the charge curve ?
All the cordless battery packs have a temperature sensor inside them - to
prevent overheating the pack when pushing charge rate to the max.
I think you would want same thing trying NMH batteries on Elec-Trak.
