In a smaller (28ft class C 12v system) motorhome noise is a factor to me. I have heard the AIO unit fans are very loud. I do not know anyone personally who has one to ask about them. As it would be mounted inside my rig, this is a big concern for me. Thanks in advance.

I have searched this forum and could not find this question. Looking into purchasing an EV. How much solar and batteries is needed to fast charge typical EV? With California mandating all electric by 2035 and the state of their grid, us less knowledgeable folks would like a ballpark answer for...

I keep seeing the word serial used in battery hookup discussions. Don't they mean series? I am just a little confused why?

I diy'd a 12v 280ah w/JBD 200amp bms with bluetooth. I also have a victron smart shunt available from another project. Is the JBD bluetooth reliable enough to not need the smart shunt? I'm installed in a class C motorhome. I boondock one weekend a month (4 days at a time). I don't need exact...

Is there a problem having a 24v to 12v converter running 24/7 in my motorhome? Should I shut it down if I'm parking the rig idle for a few weeks at a time? Are they designed to run constant?

I have a question: 2 12v 100ah lfp batteries in paralell. One has bluetooth. How accurate is my bluetooth going to be as far as SOC and up to the min amps in and out? Do I have to double or half the readings? What if it was in series? I am not going to keep this setup very long because I have...

I seem to remember on one of Will's videos a mention of another bluetooth app he prefers. I can't find it. I have I-Phone. I could only find android app. Does anyone know anything about this? Does anyone have a link?

I have a Class C motorhome. I am building a 280ah LFP. I am going to make it portable for when I store my rig. I only use it 2 times a month and store it in a medium secure place. I need to take the battery out every time I store it. I want to use something like the Anderson connectors. Use a...

Want to build my first battery. Going to get 4 EVE 280 cells from Amy. 12v build. Looking at the: JBD12V200A BMS. Do cold or hot temp sensors come with it? If not where do I get them for this BMS? I have solar grid tie system at home. Love it. Now building battery for my older class C...

If I store my rig with the solar turned off before and after the charge controller and pull the batteries, do I have to use a resister at the inverter every time I fire it all back up? Will it somehow spark like in Will's videos and do damage? Also if I switch off the inverter when not in use...

Just a word of caution: Check your solar panels often. I was setting up for an outing with my Class C. I happened to look up at my roofline. My one solar panel looked odd. It did not look quite right. The front corner seemed tipped up a bit. Not a lot but it looked off a little. When I got up...

Is there any info on the amount of lift we are dealing with on the roof of an RV? My thought is that the lack of aerodinamics of a motorhome would lead the air up over the solar panels and not affect them. Possibly creating a dead air space. If anything, a piece of flat aluminum sheet down from...

Just curious. Why not use one large (350w or larger) on an RV. Would it not be easier and less holes in your roof? Alt-e-store offers a 49volt - 415watt panel for $217. This is cheaper than 4x100w panels. Then you only need one set of holes in your roof and only one set of wires instead of sets...

Getting my RV out for the season. Cheapo controller needs replaced. I have one panel on roof 165w and 18v. If I replace with a very large panel 250-400w but at up to 36v can I use a 100v 30a Victron controller and still get 12v out for my batteries? I have had one panel on the roof for over two...

Just a general question: At what lengths do I need to worry about cable related loss? From 1 ft. to 2 ft. of wire is there much difference when using: 10ga? 4ga? 4/0ga? I understand with longer lengths - 10ft, 20ft, or more can have substantial loss.

I live in Las Vegas. I use my RV during the cooler months. I store it during the summer. I have only one 160 Watt panel installed. I may get a 350 Watt panel to replace the smaller one. I only have room for one panel on my roof. My question is if I disconnect the input to controller so no...

Does it work the same in AC as in DC when using series and parallel circuits? Voltage increases in series and amperage increases in parallel?

When I needed new batteries for my Handicap scooter I purchased two LiFePo4 50ah 12v batteries. They are combined to make 24v internally in the scooter. Can I use the external 24v 4a charger that came with the scooter without damaging anything? Do I need to get a LiFePo4 charger? It shuts off...
