Slowly getting slower

[Airstream65]

My 2003 DS IQ seems to be getting a little slower on flat ground and uphill. I wrote a lengthy paragraph on “ another battery question “, earlier tonight explaining my batteries, which I assume are good, volt metered each batt and reset obc, etc. I have 4 gauge cables and a speed magnet, 10” tires and no lift. I replaced the positive cable end going to controller because of slight corrosion, but did not help! Any thoughts?

Batteries are 2.5 years old. I checked each battery with a digital volt meter with cables unhooked, each read 8.5 and 8.6 24 hours after charge. While driving the pack voltage drops to 47.2. I reset the obc per Sergios direction, with voltage reducer unhooked and only pack negative on battery, while charging, the voltage gets to 65.2, then goes down to 51.2 hours after completion. Any suggestions, please!

From your other post

What kind of speed do you get with your setup? What did you get previously? How much speed do you lose uphill and how steep are the hills? Where do you live and what are the temps there?

Hills are not real steep, the top speed is about 19-20 mph according to gps, inclines about 11mph. I live in Oklahoma, temps are in the 40s to 60s in the winter. The flat speed isn’t really bad, but inclines seem slower.

FWIW, my 02 IQ does 20 or so. When it had 6 year old Trojans in it and a speed magnet, it did 18-19. Now it's got brand new Crowns and an older Alltrax and it does 20...maybe 21 with the windshield down. Zero hills, so I cannot offer a number for you.
