LiFe charger/discharger (capacity tester)
 

Does anyone know of any LiFe charger/dischargers/cycler that will record and tell you capacity of a cell?

In case anyone else is ever looking and finds this thread. I have found a charger which does this. It has a 40A max charge and 40A max discharge, more than enough for most applications.

The price tag isn't tiny @$240, but if it helps save a couple lifepo4 batteries it pays for itself.
