Re: Upgrade to Lithium FE battery question
The Victron controller already have bluetooth and I can see how many watts are coming in and going out, battery voltage and solar voltage. Not sure what functionality a Shunt will add. I mentioned below the converter is WFCO wf-8735-p. It's made before LiFeO4 days and it'll bulk charge at 14.4V. My LiTime manual says bulk charging voltage is 14.4. Only the absorption phase is where the WFCO convert falls short at 13.6V where the LiTime wants 14.4V for aborption as well. That's where I think the solar Victron will be able to top off the battery in absorption phase.1.5KViews0likes0CommentsRe: Upgrade to Lithium FE battery question
Thanks StirCrazy. I live in Colorado and mainly go camping in Colorado and Utah. Sun is very good here. With my old two AGM 100Ah batteries, they're usually topped off by the 200W solar by 10 AM or so. We also have a Jackery 1000. We use that for coffee maker and microwave when needed and Jackery can usually handle 2 to 3 days of coffee and Microwave without charging. Having a build in inverter in the camper would be more convenient but no need to spend that money now is nicer.1.5KViews0likes1CommentRe: Upgrade to Lithium FE battery question
Installed the LiFeO4 batteries today with a Victron MPPT charger, and verified the charger is charging the battery and all 12V appliances work inside the trailer. My current converter is a WFCO wf-8735-p which charges in bulk mode at 14.4V for up to 4 hours before dropping to absorption mode at 13.6V. The only issue I see with this converter is that it'll not able to top off the battery in one shot. Since I have 200W of solar panels, the solar MPPT charger will top off the battery. So I'm thinking I can save the $ and using the existing converter. Anyone see any issues with that thinking?1.5KViews0likes3CommentsUpgrade to Lithium FE battery question
I currently have two Renogy AGM batteries, hooked to a Renogy PWM Solar Charge Controller and also charging from the converter. I just scored on a pair of LiTimes LiFEO4 batteries. Plan to install them in the spring. I know I need to upgrade the Renogy PWM Solar Charge Controller. Do I also need to upgrade the converter? The trailer is a Starcraft 2017 model. Currently parked in storage and can't remember the mode of the converter.1.7KViews1like11CommentsRe: Is I-40 through AZ easy this time of year?
I-40 through Flagstaff is at 7,000 ft. Snow is hit or miss through there in the winter. It snows a lot in Flagstaff but the sun is also very powerful melting the snow. This site says Flagstaff gets over 100 inches of snow in the winter. https://www.flagstaffarizona.org/plan-your-trip/snow-ometer/#:~:text=At%207%2C000%20feet%20above%20sea,Let's%20play!511Views0likes0CommentsRe: "Service Trailer Brake System" message on Suburban

If there is a short, it may have closed the circuit that the truck checks to determine if a trailer is attached but not all the circuits check out, so it gives you a warning. Particularly if the issue is intermittent. When the trailer is hooked up, all the circuits connect, so it thinks things are fine and enough juice may be getting back to operate the trailer brakes...so the warning goes away and your brakes work. Had an issue with our ford where the wire to one of the trailer brakes was chaffed and a strand was intermittently hitting the frame setting off a similar issue. Okay will definitely check the wiring behind the plug when it warms up this weekend. Thanks!6.8KViews0likes0CommentsRe: "Service Trailer Brake System" message on Suburban

I have replaced the dash's trailer brake controller. Super easy to do. However didn't fix the problem.6.8KViews0likes0Comments"Service Trailer Brake System" message on Suburban
In August during a camping trip, the message "Service Trailer Brake System" came on the dashboard when the trailer was not connected to the Suburban. I checked all the fuses and they were good. I hooked up the trailer to the Suburban and the message went away, the trip home was fine and trailer brake worked fine. Unhooked the trailer at home and the message came back on. I checked the 7 pin connector in the back and everything looked good. I replaced the OEM Trailer Brake Controller thinking it had to be that thing. After replacement, the message stayed on whenever the trailer is not connected, and the message goes away when the trailer is connected to the vehicle. We have done two other trips since and the trailer brake worked fine each trip. Hooked up the OBD II reader and there are no codes. It feels like the Trailer Brake Controller thinks there is a trailer connected to the vehicle when there isn't a trailer? Any thoughts?7.5KViews0likes8Comments
