Form factor is very important to me, since I’m considering these for my Sprinter van, and also for an off grid shop / adu. But I haven’t seen any other battery with as many features, regardless of size. Some have 200a discharge, and maybe internal heat, this is the first I’ve seen with an...

Yes, thanks. And I found floor heaters are still made.

I’m no expert but this seems like an impressive battery for the form factor. Has all the goodies: Internal heat that can be controlled externally. 200amp discharge rate Tested over 4kwh Bluetooth

If any excessive heat 2 vents and a usb cpu type cooling fan w tstat should help with minimal parasitic draw.

Yeah interesting and I’m looking for units to compare with the SS EG4 dc powered heat pumps. Couldn’t find any prices on their website, which usually means high prices in my experience. Anyone else have feedback on these dual voltage heat pump units?

Gas / propane floor and wall units do not have fans. But all may have an electric (likely low voltage) requirement for a thermostat and/or gas valve control. I’m not sure if gas floor heaters are even made anymore, I’ve only seen them in old homes. They actually work pretty well… since heat...

I love Vanagons, especially the two I converted from the gutless 48hp diesel they came with to 90hp 1.8L gas golf engine (bombproof). They were all my surf and camping rigs. Having had a few Vanagon Westfailures, wondering about the effect of heat from the nearby engine compartment on the...

Yeah, the price of bougieness.

Yeah I think that’s pretty much True for many components made for the solar industry.

I’d almost bet they have a latest greatest updated model coming out soon…

Anything else? ? Seriously though, yeah I’d like to see all that as well.

Haven’t run accross any tests on this yet, but given the Bluetti marketing proclivity of over simplifying what it takes and how much energy it takes to power a house I have some doubts. Notice a lack of any cables visible on the marketing propaganda video or pics. And lol on their customer...

Interesting. perhaps I missed it, but I didn‘t find anything about low temp internal heaters in the specs. Since it is shown living outside I guess they just figure oh well deal with it. Surprising to me since it’s from Canadian Solar. I would think that might be a consideration up in the great...

Why not just ask it here? That way we all learn. That’s the point of the forum, sharing information. Sharing is caring ? ?

I would say don’t assume. I bought a very used and battered 315w panel and have seen 340w out of it, and 320-330w fairly regularly in ideal conditions. Update: today it was cool (40’s F) and cloudy with some sporadic sun. I saw that very used and battered 315 watt panel hit 370 watts...

??‍♂️ RIDICULOUS. Perhaps a reverse scam.

What are the qualifiers for “power user”?

From what I’ve seen, this Vestwoods battery appears to be the lowest cost per watt pre made 24v battery that includes a 200a bms, high and low temp protection, and bluetooth. 25.6v x 220ah =5632w for $1339.99. so that’s 23.8 cents /watt, plus whatever your sales tax rate is if applicable (free...

I have a Vestwoods 250ah Ultra. Bluetooth works but it really sucks in that it: 1) doesn’t allow renaming the battery so you’re stuck with a long number as it’s id, in tiny font. 2) it doesn’t seem to remember the battery. I have to find my battery each time and select it from a long list of...

Anyone have experience and/or info on other brands of hybrid or direct DC/AC powered mini split heat pumps that function like the EG4 offering? These seem to be hard to source except alibaba (which is a nope from me). Amazon search really leaves a lot to be desired, as usual they just lump...

Solid-State Battery Has 2x the Energy—and No Anode https://spectrum.ieee.org/amp/solid-state-battery-no-anode-2659660965

What’s drawing you to the Pioneer? Totally understand just using a normal 120 or 220v unit if you have a system with plenty of power to run it and don’t mind the inverter loss. I’ve looked at the Mr Cool 4th generation units Costco sells. But there’s 120 and 220v 12kbtu units on amazon for...

I get that. But does everyone want to buy a vac pump - yet another tool cluttering the place- to use once? Not me. If you’re not in or near an urban area it can be challenging and likely expensive to get an AC tech to drive to you, driving overall cost and payback period up. And talk to any...

Amprius has an interesting battery technology. Quite energy dense. I posted info on it recently and the response was basically ? and “meh”. I on the other hand find it exciting and think one of these new chemistry batteries will hit, so am always interested and optimistic when I see such...

Thanks for the bit of terrible history. So bad marketing strategies by todays standards, or any standards in my view.

Uhh what? Jeez tough crowd. Wondering if you’ll be “staying with what I’ve always done” if you happen to need new batteries when (inevitably) a better battery technology is proven, available, and cost competitive.

That’s the Spirit! Fortunately Thomas Edison had a different outlook…

500wh/kg or 1300wh/litre Silicone anode 0 to 80% charge in 10 minutes. https://amprius.com/ If it requires cobalt in it that may be a deal killer for some. And I wonder what the real world cycle life is.

Good to hear. How long have you had it? Thanks

Anyone using either of the EG4 Mini Split units for heat, and if so how’s it working out? Running on solar or 120ac, either way I’m interested to hear how well it heats.

Yes of course, why wouldn’t I? The sun is out plenty of times when it’s 41F or lower. And 41 is a bit of a chill, but it’s well above most LifeP04 bms charge parameters of 32F. And hardly what many on this forum would call pretty cold. If the sun is out or I’m going for a drive and the...

That SFK battery is interesting. I absolutely love that external temp control option. It appears continuous discharge rate is around 100a, does that seem a bit low to anyone else?

Nice, but notice Charge Operating Temperature: 41°F to 122°F 5°C to 50°C

Yes Lithionics and Victron are top tier. The small size but high power of the subject batteries are what I find interesting, or questionable. If they are for real, good quality and dependability at a reasonable / competitive cost, then I like the trend. But I understand, some companies are not...

It’s my understanding all these foams degrade with age and high temps, I believe “thermal drift” is the term. I’m planning on using foam to insulate a future battery bank in my Sprinter van, and the walls and ceiling of a recently acquired 12x7x6.5ft (stationary) storage trailer. Which foam...
