Unfortunately, having them closer together just isn't possible. I really wish it was. Due to weight distribution with my travel trailer, I need to have this weight spread out in the two locations. The side compartment was great for the Bluetti, but it's the only place I'm going to have room to...

My travel trailer (that I'm full-timing in) currently has two separate power systems: Two 12v 250Ah Chins self-heating bluetooth LFP packs (~40 cycles on them) paralleled in the front compartment along with a 100A PowerMax charger right next to it, all cabled to bus bars with 4ga copper cabling...

I've seen a lot on here about Rich Solar's CIGS panels and their delamination issues, but has anyone used BougeRV's Yuma CIGS panels? And, if so, any reviews or thoughts on longevity? I currently have two BougeRV Yuma 100w panels (one long and one compact, both adhesive-backed) that I was...

Now we're cooking with gas! Connected my new PM3-100LK directly to the bus bars via 1.5ft 4ga pure copper cable , and it's pushing the 100 amps no issue. I'll probably switch to some nicer 2ga cable I have with factory-crimped ends, but right now, things are working great! Thanks everyone for...

It was less of a "I'm worried about 3.75v in particular" situation and more of a "why didn't protection re-engage when it hit 3.65v again?". Shouldn't it re-protect at 3.65v? Great call on the inrush feature - that's something I'd actually use. I set my house (my real house that I'm never at it...

Yeah, I mentioned that they were CCA. Sure would be nice if they used solid copper, but everyone is cheap these days. I even saw 15ft jumper cables at Kwik Trip earlier this week that were 10 AWG - my jaw dropped. I will try running up the voltage later today and cross my fingers that the BMS...

Interesting results doing some testing tonight. Since I have previously had a 60A standalone PowerMax PM4 and then a 55A PM4 MBA model, I thought I'd do some testing with my new 75A PM4 MBA before I plunked down a couple hundred dollars on the 100A PM3 or PM4. Using what I had on hand (since...

I might just go all the way up to 100A - giving it some thought... Do you know what the specific differences are between the PM3 and the PM4 (besides the PM4's "4-stage charging" that I don't use anyway)? PowerMax's literature isn't the best. I can save a fair amount by getting the PM3 via...

What may be prudent for me to do is to just put a charger closer to the batteries rather than ripping out all of the existing cabling (cheaper as well), especially as I have an AC outlet available right nearby. I originally sized my system so that I would utilize my 1800VA power budget (rated...

I'm hoping that's not the case in my scenario as I'm not using battery charge mode but rather constant voltage output mode. The fan sure is annoying, though...

Wires aren't warm, but with such a long run, the small absorption from the wires could cause enough loss without a lot of heat I'd think. @DIYrich - One of my problems, actually - converter is far (electrically) from the batteries but not from the other loads, so adjusting the voltage upward...

Perhaps I was a bit optimistic on the charging speed. While it does occasionally hit 40 or even 45 amps when the batteries are quite low, usually charge rate is around 35 amps.

Long-time lurker, first-time poster. I'm running into an issue with my battery system in my travel trailer, and I was hoping that y'all might have some insight. I'm running into an issue with very slow charging of the 500Ah of LFP batteries in my travel trailer, and I have hunch of where the...
