MikeR: well you'd be surprised how many people do need a stinkin' manual!
It would only take minor effort to create a quality manual for the C4.1.
MikeR: Yes, let us know how they turn out. I haven't made the jump to Nimh batteries yet, but I will for the start of next years outdoor season. I really want the 3000HV so it would be good to know they are worth the money.
