Basicly compare the internal resistance of batts to pick out bad batts.
I wonder if I'd get any useful measurements/results.
I have two models here :
- a ÁMetros from Mr Cam ( DIY )
- a RIM 1000 from Conrad / ELV ( Germany )
Both work pretty well ... and give same results.
But which results !!! a bit far from the 1Khz tests ( significative ??? ) of cell constructors
... but true.
One thing is sure : it is a very good instrument to detect cell differences ... It can also show the charging state , as internal resistance is a function of charge ( and rest ...)
Don't be sad when you will discover batts are " not so perfect " ...
