Do you have a link to your switches? That sounds neat.

Hi y'all! As I catch up on all the latest info (I built my batteries 2 years ago) I see a lot of chatter about active balancers. I already own 2 Overkill 8s BMSs for my 2 24v batteries, so I figured I'd add a NEEY 4th gen 4 amp active balancer to each battery and call it a day. Then I saw the...

Thanks for all the advice, I think you guys all shed good light on the situation, and why the dome lights in the van are wired the way they are.

This may be a silly question, but I'm new to wiring the DC load side of the house. In the past I retrofitted a travel trailer with 24v LiFePO4 batteries and an inverter, but all of the house wiring from the 12v distribution/fuse box to all the switches and lights were stock from the RV...

QQ: 1.) Do y'all use anything as a shutoff between your solar panels and the charge controller? I've looked at 1 combiner, and think I'd like to use them for this purpose, any recommendations? 2.) What are we using these days between the solar charge controller and the battery? Will's schematics...

FilterGuy, thanks for addressing all that. In one way or another you addressed all the concerns I had listed, and other thoughts that I have had, but hadn't gotten around to in the original post, because I didn't want to detract from my primary concerns/thoughts. When I do my math, I tend to...

I've built a 24 volt battery system in a travel trailer before, but I never got around to installing the solar. So... current concern (pun intended). My inverter/charger is 3000 watts, capable of charging the 24v battery at 120 amps. If I add a solar charge controller that's capable of 50...

I didn't want to, but I'm starting to lean towards Victron, I just never saw myself as a Victron kind of guy. I liked the EPEVER Tracer I used in the past. I want something that will work well. The purpose of camping isn't to spend time fiddling with the electronics and hoping the lights come...

Hi all! I'm building a new DIY camper and I'm looking for advice on a charge controller. I'm re-using some components from a previous build, but am buying some things new, thus some of my components are locked in, others aren't. I am open to any and all sound advice! We do plan on running a...

I'm building this trailer myself from an enclosed cargo trailer. I currently have no intention of connecting my house wiring to the 12v of the trailer. The trailer wiring will be it's own system that is just used for the trailer lights and trailer brakes. Does my system sizing look OK? Or am I...

@TacomaJoe I appreciate your concern, at this point, I wasn't too concerned with details, but just wondering if it was possible, if so, then it's just free SoC for driving I'll be doing anyhow. I've got 8.64 kWh of LiFePO4 in 8s2p, 16 CALB SE200 cells. I'm planning on 1,365 watts of solar 3x455...

Thanks for all the help, I'll see if I need to do that once I get the packs re-assembled. Last night at 8:00pm I was charging at 0.96 amps, I'm now down to 0.36 amps. Question: Is there any harm in leaving it all hooked up until it goes down to closer to 0? Even if it takes days? I ask...

Possibly a stupid question, but my wife asked and I couldn't say for certain. We're planning a long cross country trip this summer, I'm planning on 1,365 watts of solar for our travel trailer's roof. Will those panels charge our batteries while we drive? It seems like they obviously would, but...

Thanks for all of the advice. I'm reading 3.61 volts at the cell terminals, which has me happy. Currently only at 1.35 amps, so I'm thinking we're near the end here. @Browneye , any tips for how to do this? And how to determine if it needs to be done?

I had the foresight to label the cells and track which cells were where via spreadsheet. As an update, I'm excited, voltage at the terminals is up to around 3.41 from 3.35. Amps have dropped from 10.3 to 10.1 and voltage on the power supply has jumped from 3.5 to 3.6. From what I understand...
