Yeah, me too. I guess I could extend the longevity of the USB C end of this charger (which I just received today, amazing next day delivery) if I found a female to panel mount. That'd mean the charger's plug wouldn't get disconnected really ever, but I do wonder about voltage drop. Highly...

So I have a knock off pelican case with a battery inside, and want to put my charge controller inside too. The PV input will feed through some panel mount connector on the side of the box. Thing is, I have another one of these portable (less portable) battery packs and don't really want to buy...

FWIW, just charged my 90ah lifepo4 pack up to 100% using the above dongle thing. I set my Victron charge controller to a max of 4a charge current and it resulted in 68w of power being delivered to the battery using a macbook 87w usb c charger. I used a medium grade 6.6ft long USB C cord which...

How does one determine that charging is occurring, did you mean manually? I'm trying to put a spare Victron 75/15 in a pelican case with PV and battery extensions to panel mount jacks on the outside of the case. I don't want to rely on passive cooling from vents alone. Would be sweet if the...

Related, but I received one in the mail the other day and finally got around to testing it out. 20.2v coming out of a very standard common polarity barrel jack, 2.1x5.5mm. Inside the black box is a usb pd trigger which has a button to adjust the voltage. These are just shipped at 20v which is...

Can confirm.

I have the victron 75/15 running 2x100w renogy panels but in series. I know I ran them in parallel over a two year period with a few PWM cheapo controllers before I went MPPT. Sadly I don't remember anything about power stats, or observations when I initially switched. If your wiring is...

Damn, what a rollercoaster of emotion this has been. Joy that jonyjoe has done it with lithium to lithium and a bunch of other tests, sadness at John's response, hope that a $20 solution exists from luthj's post, sorrow seeing it not be endorsed by John and then (?) dismissed by luthj with the...

I'm assuming you only run the QNBBM on your primary larger pack? Does your BMS on the 27ah only balance when cells are up to 3.6v or whatever most of them claim? Also re: the quote, is that sentence correct? I'm thinking 12.5v 32ah battery meets 13.35v 90ah battery... is that truly close...

Hopefully my diagram explains what I can't manage to do without producing a wall of text (it still happened). I was going to be paralleling a low state of charge 18ah aux battery to a 200ah(2x6v) golf cart battery floating at full charge, both lead acid, and that apparently was okay since the...

Yeah :| I had two choices, spend $50 for an upgraded VE Bus bluetooth smartwhateverdingydongle or $118 for another new/upgraded 75/15. Bought the new 75/15. I could have upgraded size but I don't have any more room for solar with 200w on my roof. I'll use the old unit and its incompatible...

I just got everything assembled and created a network from the BMV. I don't have the option to create or join a network from the 75/15 though, so I don't know how I can pair these two items together. I do have the option that you showed for low temperature cutoff and when tapped it shows a...

I haven't much to add, but I installed the balancer you linked on my 4x3.2v 90ah battery setup last night. It definitely works, I have an additional harness for monitoring... but good grief the noise. My cells are off by like .003 and yet it continues to work, producing the most irritating...

Might want to take a tape measure out and check the depth of that compartment, but I'm sure some AGM offering could fit on its side, or maybe even standing upright if you got one with screw terminals on top/side and no posts. I just googled the factory rx400h 115v inverter and found a thread...

I'm thrilled that he keeps things at the level he does, and I know he does so intentionally. It's good info. For this product in particular, compare vid to what's on Renogy's website :cautious:

Anyone who's brave. I don't know anything about either brand, but the ones on the left have excellent reviews on the battery itself and the tools running them - same with ones on right, could be fun to test. Purchase & charge the night before a weekend trip, use it to cut up all the ground...

I'd do as continuecrushing mentioned and run a slightly larger wire. If the cost of your wiring at 10 gauge is a couple bucks less than 8 gauge, may as well. I hate running wire, but it's all the same to me until you reach a diameter that won't easily conceal beneath door trim panels or...

Since you already have the smaller inverter, you could use that for now and easily upgrade to your 20a DC-DC idea later if you need to. Venting shouldn't be a concern with AGM, and you might need an AGM anyway if you're trying to stash it beneath something (ability to lay AGMs on their side).

The good doctor just made a video on this unit for anyone wanting to watch a nice review.

Quality post, here's a youtube video on different mufflers if you're interested in trying other things. This guy's channel is great for learning how these units operate.
