[RE-wrenches] FW: Battery impedance analyzers

[Larry Crutcher, Starlight Solar]

Thanks Tump and to everyone else that offered input. I have purchased  
a Biddle M-BITE impedance tester. After I have learned to operate this  
multi-buck unit, I'll give a report on how useful I think it is for RE  
system batteries.

I also use a West Mountain Radio CBA II with the 10X amplifier that  
let's us do temperature compensated discharge tests up to 500 watts to  
verify the actual AH capacity of a battery. The impedance test should  
only take seconds per cell so I hope it replaces this discharge method  
of testing.

Kindest Regards,
