Costco 6V battery charge rate
Hello, I have few questions. I have searched and could not find a direct answer. First, I list what I have: I have a 135W panel on roof. Yes, I plan on expanding with 2 more panels some day....

I would do this, and I would verify the voltage of a fully 100% charged battery at the battery terminals to be 15.0V, not what the charge controller says it's set at, there are voltage losses from line and length of copper wire run.
Yes, I got digital multimeter to measure the voltage. Just that I am not quite familiar with 6V batteries and its charging characteristics. I am much more familiar with 12V batteries of various configurations. I calculated my voltage losses from the panel to the batteries at 0.7% using 4AWG cable 18 foot distance from roof to the batteries (one way). The controller is located next to the battery compartment using 2 foot length. I did not use battery voltage sense wire but I could put this on if any of you felt its value is warranted to use it. I am using the remote temperature sensor on the negative post of the last 6V battery in the series. I hope I am doing the optimal practice.
I do have Progressive Dynamics PD9260C with charge wizard pendant already. My 5ver is parked next to my house but I don't need to have this camper plugged in all the time if tristar does a better job.
