Confusion between Peukert Effect and charging efficiency? The Trimetric instruction manual has some good notes on all that. Worth a read.
Also the Magnum manual has something about the specs being at 25F it goes off the specs other than that, and he was having all sorts of over-temperature problems causing it to do its charging pull-back trick.
I don't trust all this kill-a-watt method instead of just reading the amps without really knowing what the conversion factor is. Needs a calibration cross-check. But to do the cross-check you need an ammeter, so just use that in the first place :)
Yes, I think I have started to jumble it all up in my mind. So basically Peukert Effect, not significant enough to worry about. Charging efficiency, really significant losses there, however if you use a DC ammeter between the charger and battery the losses are occurring before you get to the ammeter. Then, Ah out should be pretty close to Ah back in. Think I've got it now!
