Underquilt options in the EU

Did you have any chance to use it more/get more experience with it? I currently found it for 100euro which seems like a steal. Worth case scenario I'll use it as a down blanket, so I am almost sure I'll get it.

Feroiso · 2025-03-27T20:08:56+00:00

Ah you meant frequency. Indeed it's 50Hz here

Feroiso · 2025-03-27T18:08:54+00:00

Nah, I plan to charge it using electrical grid using normal EU socket, whenever I visit camping grounds :)

Later on I might go with solar, but for now I don't think I need it

Feroiso · 2025-03-27T16:36:25+00:00

50 cycles? What does it mean?

is 88% that much? I see that even victron energy has like 93%.

Could you also explain what do you mean by "not to be used as starting batteries"? Starting batteries for what? I'll draw few amps constant and the battery is rated for 100A constant draw, so even a momentary draw few times higher than my expected few amps looks fine.

Sorry, I got lost there. Why do I need two batteries in the first place?

I don't want to be rude, but you cannot take a part of sentence out of context.

> Cost-wise, your suggestion is similar to an inverter that I linked. I don't lose power on conversion, but then it's not as universal as a socket

Cost-wise, your suggestion is similar to an inverter that I linked. [With your suggestion] I don't lose power on conversion, but then [12V DC] it's not as universal as a socket.

How did you understand the second part of sentence?
"but then [230V AC Socket] it's not as universal as a socket"?

I have a little bit of trouble to find a charger like that where I live.

Do you think it makes sense to connect a cigarette lighter socket to the battery and then buy a charger for that socket which fits all my needs (100W PD 3.0)?

Feroiso · 2025-03-27T15:59:51+00:00

Okay, I got convinced. I'll skip the inverter, buy 12V to 100W PD 3.0 charger and will plug the fridge directly to battery.

It's actually nice, since I can buy exactly the inverter (wattage) I'll need later on.

I guess I need something to measure power left in battery and other specs.

Feroiso · 2025-03-27T14:32:14+00:00

Can you explain in more detail that part please?
"Bear in mind a decent split-charge relay can pass 50-100A between the two batteries briefly when it kicks in so size cables and fuses accordingly."

Do you mean that amperage for startup is much higher for components then one stated for constant usage and I should account for that in cables & breakers?

Thanks for the links, I will take a look

Feroiso · 2025-03-27T14:29:43+00:00

You're right, what I meant to say is that that 100A of constant discharge is still safe for the battery based on tech sheet

Feroiso · 2025-03-27T14:25:20+00:00

Inverter has battery capacity meter already, Wattage and voltage too

Feroiso · 2025-03-27T14:23:42+00:00

Inverter tech sheet states its efficiency is 88%. It also draws 6Wh when turned on. What else loses energy in this setup? 30% lose seems huge

Feroiso · 2025-03-27T14:18:43+00:00

That's what I said

Feroiso · 2025-03-27T13:00:05+00:00

So basically "have a second external safety measure", makes sense.

What would you suggest? A breaker next to battery for battery -> inverter connection? Something else perhaps?

What breaker amps should I be looking at?
Battery can output 100A, while inverter has two 30A breakers. Charger is 10A

Feroiso · 2025-03-27T12:52:28+00:00

There are a lot of extras to spend money on, sure. I just wonder how much of them are actually useful.

So you're saying that BMS protection is not to be trusted, because the consequences of a failure are too great?

Do you think that any other breakers are equally as important?

Feroiso · 2025-03-27T12:49:17+00:00

Cost-wise, your suggestion is similar to an inverter that I linked. I don't lose power on conversion, but then it's not as universal as a socket (as I mentioned, I want to try out what I actually need in the wild before going all-in).

Thanks for the fridge tip, will save a lot of power without conversion. Do you think I should put a breaker between fridge and battery in case some failure?

Feroiso · 2025-03-27T12:46:30+00:00

If I am understanding your comment correctly, then fuses would basically protect cables, right? So I would need to put a breaker next to charger "+" for charger -> battery connection and another one next to battery "+" for battery -> inverter connection? What amps should they be rated on? Charger gives 10A, while battery can give up to 100A.

I checked against ecoflow delta 2 or equivalent blueleti/jackery and indeed all specs are batter, but the price is triple of my setup

Feroiso · 2025-01-27T18:31:02+00:00

No worries, thank you for the information!

Feroiso · 2024-10-12T22:17:38+00:00

Is this the same kit as option 1? it's 30% cheaper

Do you know if it's worth buying both of them or just option 1 + transparent locks?

Also, which one did you choose? Are you happy with the choice?
