Can't figure this out. Replaced new batteries with lifepro, and. New converter. I have 300 watts of solar and am boondocking at the beach with complete sun. Went to bed with full battery 13.4 volts, woke up(6:30am) to battery with 12.6 volts. Renogy. Battery monitor said it was 65% full...

We have a 2021 2509s and am going to be doing boondocking so getting setup for that. I eventually want a solar setup but going to start with a dual fuel generator. I plan on getting s 12v 200ah lifepo battery to start. I hope to place it under the murphy bed. It will be a smart battery so I...

Upgraded to 2 LifePo4 100 amp batteries, seeing posts to disconnect alternator wire to camper to prevent frying of the alternator. Is this a real concern? Should I cut the black wire from the 7 pin connector? I have the HW277 wiring diagram and it seems logical. Batteries will still power...

Hello, Recently upgraded to lithium 300aH watt cycle battery, replacing two gc2 6v I have the ancel Bluetooth bms, as well as a go power solar charge controller On our first boondock trip I had a large discrepancy between state of charge between the two, however the voltage reading was exactly...

Looking for some guidance on my Magnum controller settings after upgrading from lead acid to LiFePO4 batteries. I have a 2019 Berkshire 39A (onboard generator, no solar, unsure of alternator output). I just swapped out the old lead-acid bank for two SOK 12V 206Ah LiFePO4 batteries — mostly...

A bit of background. I have a 2019 Rockwood 2706WS with a 350W solar setup on the roof and 200W mobile solar. I currently have my trailer permanently stored at a site without access to shore power. I go to the campsite about 1-2 times a month from Thursday - Sunday. I have a 5500-w generator...

Electrical issues perplex me, so I appreciate the help........................ Can someone please summarize what I can expect in terms of output from an 180 amp alternator on my 2017 Jeep Grand Cherokee thru the 7-pin connector to the TT ?? And, is there a way to actually measure the output at...

I have everything I need to switch my 5th wheel batteries to lithium. I have 2 100AH 12v lifepo4 batteries. They came at 50% charged, I am wondering If I need to fully charge them before the install or can I install them and then let them charge all the way and try to reset the new battery...

Can leaving my lifepo3 battery switch on in my 2022 Vibe 28RB trailer and hooking up truck power to trailer cause my 2019 F250 dual lead acid batties to have sulfuric acid vapors come out of the battery vents? This happened after a 3 hour trip. Google search states no, states possible over...

Does the BIM allow the chassis batteries to charge on shore power.I thought I read MB didn't allow it. Can a dc-dc charger be hooked to the house side of the isolator relay if charge is only from chassis batteries to house batteries. New to me MH. Want to change to lithium. Have no experience...

Hello all! I recently switched over to LiTime 140AH lithium battery as well as their lithium-compatible solar control charger. In doing so, I had it wired at the dealership. The solar panels are not charging the battery at all, and the solar control charger isn’t even sensing that there are...

Hi all, new 2021 Wildwood owner. It came with go power solar installed but the solar does not appear to be charging the batteries. I’ve gone through the solar users manual and can’t find anything that is helpful to troubleshoot it. This is my first time with a camper that has solar so I...

I have been itching to get a bigger capacity battery. Today, I just purchased Elefast 330Ah lithium battery for $400. It's on sale right now, a $10 savings. 😆. Hey, $10 is still good dinero. https://a.co/d/gk2LWGm I have seen another brand Mjbsan 330Ah for $410. Techcella 320Ah for $400...

2025 Forester 2861DS I'm not impressed with this solar controller, the manual is clear as mud. I'm having an issue with the batteries appearing to be in a low voltage state although the controller shows 12.6-12.8 volts. We were on a weekend trip a couple weeks ago and upon returning I insured...

I have a Forester 2021 with a solar panel. I am considering upgrading the lead battery to a Lithium battery. The battery is charged by 3 ways: power converter with Li mode, generator from the truck through BIM, and solar panel probably thru solar controller. I can find a Lithium BIM with the...

2021 HW277 with 5 year old lead acid batteries that don't hold a charge for long. Ordered 2 LifePo4 100 ah batteries. We desire to camp at Blue Ridge Parkway sites without electric for 2-3 days. Any advice on how best to charge batteries; buy LifePo4 specific charger, or Change out converter...

Hey folks. I have a Crusader 35rlp. Storing it for the first time at a facility. There is a regular outlet I have access to. I was going to buy a trickle charger to keep the battery in shape. I noticed they sell a 50-20 converter plug. If I used my regular 50 amp cable and used that converter...

I recently switched to a dual lithium ion setup and for some reason there is no power to the jack or lights inside. Shore power also does not charge the batteries, nor does the solar controller despite being set to lithium ion setting. The inverter works fine off of the batteries, so there is...

We recently had a 42'x35' metal building put up to store all our trailers and some other equipment out of the weather and hot Idaho sun. Obviously, the roof mounted solar panels on our 2108DS don't work very well inside, and I didn't feel the expense to run power to the building was necessary...

Hoping someone can help. I have a 2018 Vista 27n. My house batteries are not charging when I am using shore power. This is something that never used to be a problem. I checked the voltage coming into the house batteries and with the engine running it's 14.5v, with the generator on its 13.2v and...

Hullo. 2019 intent 29L owner, having an issue: I’m plugged into shore power (30 amp) and my batteries are not charging but instead being exhausted. The batteries are brand new and charge fine from the alternator. I don’t have an ATS as to use my generator I have to physically plug it in. The...

I have a 2017 Isata 3. Northern Wisconsin...I put my trickle charger onto the "live" port on lower dash to feed the Engine battery. To provide power to the charger I have it plugged into the wall socket. My lithium batteries are stored inside the garage. I have the camper hooked up as normal to...

I just removed my lead acid battery for winter storage; currently stored in heated basement (~60F) and plan to keep it there for the winter (4-5 months). Question: what is best course of action to keep it maintained for the winter? Hooking up to battery charger once/month for a few hours OR...

Need some help all. Have fairly new interstate house batteries. Plugged in to shore power and batteries are not charging. Spent a whole month out at campground plugged in to shore power, no problems. Checked voltage at panel periodically and was showing 13.1. Now I have been home for 3 weeks...

I have a 2021 Coachmen Sprots Coach with a single solar panel on the roof. I would like to find out if it was wired from the factory to charge both my 6v house and my 12v starting batteries. Also if they put a charging control to stop charging when batteries are at full charge. Any help would be...
