Measuring V loss during charging
I know that a discharged battery can pull down the voltage at the charger. I was trying to measure voltage loss in my converter wiring, switches, etc. The two 105 AH batteries were 12.13v prior to ...

Thank you.
Basically, my so called 55 amp converter charger, with this wiring, is more like a 5 amp charger. This morning after 20 hours of charging, the battery voltage matched the converter voltage of 13.66, and there was about 1 amp of current. 20 hours is no problem if you are on shore power. Unfortunately the batteries will sulfate over time due to never seeing 14.4v or more. But hey, camping on shore power, who cares about the batteries, right?

And you haven't put enough thought into the issue.
If you're charging the battery with the gen then you want fast as possible charge to 80%. There are two requirements for a fast charge. They are equally important.
1. A converter that can output at least 14.6V in boost.
2. Cable resistance of 10 mohm or less.
I reduced my charge time (to 80%) by more than 3x when replacing the Parallax converter with a Iota and reducing the wiring from 25 mohm to 10 mohm.YC 1 wrote:
You are way over thinking the issue.
