Hi all.. I currently have 2 x 100w Renogy Compact solar panels on my roof rack that clock in around 40x40" side by side. This is an improvement over my previous setup which used the non-compact versions, which occupied a 40x47" footprint. I was pretty thrilled to reclaim 7 inches of rack...

Has anyone looked in to this for DIY packs? The best I can find (for boards/modules) are 18/24w max USB-PD modules that only work for 3.7V lithium batteries, 1-series. I've bellyached about this in recent years on here but now there are so many portable power station 'solar generators' out...

Quick question, but how are people strapping these down while also stacking them? I have them on a bed slide and can anchor them to the rails on the sides and down the middle of the platform, but running any strap over top of a bin means nothing can stack on top of it. Thinking about using...

I couldn't get the Victron app to work on the android based touch screen I installed in my truck. Despite it having bluetooth, it appears to not work for everything.. maybe just audio streaming. Not really a drag though, I have a raspberry pi in my diy lithium aux battery box and router which...

Does anyone see anything wrong with installing the smallest of Blue Sea fuse panel with negative bus (6 circuit) to supply a Victron Orion TR-Smart 12v 18 amp DC-DC charger? Blue Sea rates the entire panel as good for 100 amps (30a max on single circuit). I'm running 8 gauge pure copper...

Anyone seen sales worth mentioning? I ordered 3 x Renogy 100w black frame panels because it appears they're nearly the same dimensions as their Eclipse line (41.5 x 20.7), nearly 7 inches shorter than my current Renogy 100w's from a few years ago. $95 each and already received em from...

Anyone ever used one of these BT BMS units? A lot of them seem like junk visually and are often for more than 4S batteries, but I've seen a couple. I write mobile apps (iOS and Android) for a living, mostly Bluetooth LE stuff at this point including firmware for microcontrollers so apps can...

I got these stupid things yesterday and sat them side by side. Two sit flush together, two do not... so I guess there's some swelling. I'm sure not all blue wraps are the same, but they're the same in the sense that you probably have no idea ****** they actually are. Question for guys that know...

Anyone used these? I didn't even know they existed until the other day. $140 for 300w of charging power, bluetooth monitoring ability, and has a lifepo4 preset (14.2 absorption, float/storage at 13.5) I don't know what to make of that blurb above and how much of it pertains to lifepo4, but...

As title states, LIFEPO4 and thankfully things just got really REALLY hot, and one pack is fried - no damage to my pop up camper which I was using as a workbench for this process. I have (had) two identical 40-cell 26650 lifepo4 battery packs, 10 cells paralleled, 4 series, lovely 12v portable...

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...

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...

Pretty sure I've read that the smaller Victron charge controllers have internal temperature sensors. But all search results across the web for victron+temperature discuss temperature compensation, and the most it touches on lithium is "set this to 0 in the app". I don't want to charge if it's...

Or as low as $125, I just bought another 40 cells at a better price, to build a clone of this pack. I'll take pictures along the way for that one. I decided I'd had enough of the lead acid world after building quite a few ammo can and toolbox battery projects for charging things at camp. They...

If you have a rather predictable load (solar keeping battery system floating all day, fridge the only draw in the evening) could one just buy an ammeter battery monitor for 1/10th the price? I figure the worst my setup will see is an uncharacteristically warm evening @ 10,000 ft, and a lot of...

Kind of like the million b2b questions but I figure with the solar generator craze going on right now (see: Amazon), with most/all having car charge adapters, that there might be some news on how to most easily accomplish what I'm trying to do. The primary thing I run with my setup is my...

I've come to realize that I absolutely loathe the standard solar cable marketed all over the place and typically attached on the back of panels. I understand the UV resistance benefit, but it doesn't seem as important when you ground deploy panels a handful of times per year. They're hard to...

Hi guys- I can't for the life of me find anything of substance on this on here (or amazon), which in my experience means it doesn't exist or isn't popular.. Is there any simple way to top up another 12v battery without doing a dual battery setup/isolator/whatever? My aux battery + solar +...

I just posted most of this in another thread but figured I'd create a new one in case anyone was searching for some sort of ultimate music and power machine. Objective Have an easily transported boombox for camping that also allows me to charge phones, blow up air mattresses, and (version two)...
