charging batteries

I bought a used 2017 Forester TS2391 (on a Ford Transit body) with a 100 Amp-hr Lithium Phosphate battery. The vehicle’s alternator charges the coach/house battery when you are driving. It does this “through the battery isolator/relay” per Forest River literature. We have driven and dry-camped...

I have a Montana High Country 377FL and am looking to purchase a new GMC Sierra 3500 with a 6.6L Duromax Diesel engine. The one I want has a single alternator but there is another one with a dual alternator but I don’t like it as much. Does anyone have experience with this?

My house battery’s charge with shore power and with generator but not with engine running. The solar panel is cracked so that’s no help. Has anyone had this problem and found the problem? Thank you

Need Battery/charging expert. 2021 Dynamax ISata5. Has 3 AGM RV batteries in coach in parallel. Have had no previous electrical problems. Over the past couple of weeks, I've had coach out of garage, unplugged, while working on stuff in shop a couple of times. Always put back in shop at...

First post here, I hope this isn't redundant. Did a search but couldn't find anything similar so I'm hoping someone has experienced this issue or similar. Here is my primary issue: Coach batteries will not charge from the dedicated alternator while the vehicle is running. Battery charges fine...

Should the house batteries charge with the motor running while driving? This is on a 2017 precept 31ul. Because it doesn't appear that mine are.

When shore power is turned on the inverter/charger (RENOGY 3000w) will run my 120v system from shore power while charging my lithium battery. When I have shore power on the positive battery cable (2/0) is getting hot where it connects to the 300a fuse, no heat around the positive bus bar or...

Hello everyone, I am writing to ask for advice/experience with automatic transfer switches. My electrical looks very much like the schematic on this page (https://www.skooliesupply.com/solar-101/solar-101-how-a-skoolie-van-or-rv-solar-system-works) However, I am a little unsure of how the...

I woke up this morning after a night of boondocking to very low batteries (9.4 Volts). I’ve spent several hours on the road this morning and expected the batteries to be at least a bit charged up but they are still reading at 9.4 Volts. What is the best way to determine if the issue is with the...

I'm running the generator to charge my batteries. However, I'm getting 14.4V at the converter (as expected) and only ~13V at the batteries. Seeing the 13V-reading both on the battery monitor and the terminals in the battery bay. Charging also shows only 10-15A, which seems low. The leads from...

I have a Thor Tuscany 40DX 2016. The unit came pre-wired for Solar. I recently added a 190 watt solar panel to keep my batteries charged while in storage. The wiring ran from the roof to the inverter panel area. I added a 30 amp solar control box DC output to charge batteries. After 3 calls to...

Purchased a 2021 Coleman LT 262BH this past summer. New battery then, used the TT 4 times without issue. Power is connected and the microwave is working along with TV's and outlets. Nothing else. The battery volts read 2.6. Wondering why the battery is not charging. Checked the fuses and the...

I have a 2013 voltage 3950 with the Onan 5500. Main reason we bought this RV was because it had the Onan generator and it. Went to Dover this year for a race ran it almost all week (during the day) ran great until thenext to the last day when it died. Acted like it was running out of gas, if it...
