It depends how we charge. We have a small 30A AC charger and that takes around 31 hours from 0-100%, but we rarely are on that low. From 20-100% takes around 24 hours, so when we need to in the winter we park up at a campsite for a day and charge up. In hindsight, a larger ac charger would be nicer:)
These specific batteries, no, but Roamer do thier Xtreame batteries which can handle high charge/discharge down to -30C, you may want to check out @mispronouncedadventures who has been to the arctic with that battery 👍 (tell him we said hi)
Great upgrade! Looking at exactly this system for our build. Interested to see if you get enough excess solar to harvest in the summer for a 12v water heating element...
Yes with electric water heating this battery power + our solar capacity (540w) should be enough for excess, however we don't have a hot water tank, we are using our hydronic heater with a heat exchanger so we have on demand hot water. Makes it hard to install something like this unless we have a separate hot water tank just for this purpose 👀
Trying to lift that battery from above is no joke. I tried that from a truck bed with a 100 kg radiator and my back has never been the same. Three words: body mechanics. Thanks, another great vid. I have very simple wiring questions. If you have vid on heater wiring, pls let me know. Thanks!
Glad you are finding our visa useful. We do have a heater wiring vid and a schematic pdf.

Ours is an espar hydronic heater.
Well 1 hour charges us about 5% (46ah), so it would take 16hours to get to 100%...charging at 50A. On a good solar day we can get anywhere between 10-20% recharge and our daily usage is only 10-15% of our capacity, so we can actually stay topped up with the sun (when it's there) 😉
@@FreedomStrider Awesome! Yeah we're thinking of getting the 8-in-1 just to save on space, it uses the same 2400W. We have the exact same batteries here (2 x 460Ah Roamers) but we have only just started our build 😄
We were thinking using 24V but several reason why we didn't: 1. We'd already built everything for 12V, so switching to 24V would have meant alot more tinkering, plus our inverter is 12V, our MPPT is 12V, so would have involved buying those again too 2. We got these batteries before the S3 had come out so they didn't have the 230Ah 24V S3 out and we were leaving pretty pronto after this. We could have connected them together the other way to get 24V but... 3. Although 24V would have been more effecient for the inverter, everything else would have been the same and we would need 24v to 12v drop down boxes I think if we were starting from scratch, and hadn't bought anything, 24V would have been the way to go, but since we already had 12v kit, the budget wouldn't have liked it 👀
Building your own battery is cool, we have considered it, one of the key notes to building lithiums is to be quite picky with the BMS you use, to keep your batteries safe.
@@FreedomStrider I used a JBD 150amp one, not sure there's much in it between that one and the Daly but if I were buying now I'd probably get the JK with active balancing, one of the easiest jobs I did in the van and for a weekends work I have a 302ah battery for less than £700.
Wow That's a mad upgrade, I think only Seven O Savage has comparable battery capacity. You guys could run air con with that amount of power which for me is the ultimate luxury.
Yeah, the possibilities suddenly tripled with so much capacity, we are quite enjoying the extended off grid duration. We'll see how the summer is and if air con is one of the projects.
2:52 😂the battery handle did the exact same thing as my mouth! 11kWhaaaat!! That’s jaw dropping serious power guys! …It’s deceptive how big a DMC-12 is in the back! Looks much smaller in the movie 🤩
If you mean weak in terms of 'encased in a flammable couch'... then yes a full fireproof box is preferred. If you have any other fire safety notes we are happy to hear 🙂
anything more than 500ah is just for show and has no real benefit as charging becomes the biggest issue at that point, unless yoh drive for 5 hours a day
You're right that the biggest issue becomes recharge ability, as even with a large dcdc charger like ours (50a) it would still take around 16hrs to fully charge the batteries from 20%. That being said, we haven't really had an issue with recharge. In the last 4 months, despite it being winter with little sun, we've only plugged in twice for a day. The huge benefit to us with this huge capacity is we can beach ourselves for 8 days, without any sun, or turning the engine on, use the house normally, electric cooking etc...and not have to worry. Then all we need in that circumstance is 24hrs with an AC plug (which is Europe is sometimes free) and we are good to go. As the sun has come out the past few weeks, with our 540W of solar, we can actually recharge around 10-20% in a day, more that what we use. In the summer I'd imagine this to be higher so I think we'll be just fine 😁 This capacity is amazing for winter, it's improved our quality of life significantly
