- Danny is upgrading the van batteries! We’re replacing our sealed lead acid with lithium ion, doubling our power ⚡️
We are is stoked to say the least!!

Great video again….come on people those of you that are not subscribed…..SUBSCRIBE! It’s free and they do a really good job one their videos….everyone else share! Let’s see if we can get them more subscribers…..😊😊😊. I have really enjoyed your travels ups and downs…even though you guys always stay so positive. Where are you going next! Enquirering minds want to know. 👍
Mad props for you Danny. All I heard was “Greek”. Thank goodness for people like you 🙏✨👏💪
You two are going to be rolling in style after these upgrades. Very happy for both.
Hey Isabel! *Thank you so much*! We we really appreciate your support! 💜🥰 Danny, Graham, Sombrita, and I send lots of love!
Danny, you will fry your alternator. When the batteries are depleted more they can charge at 1C wish will kill your alternator. Get a DC to DC charger. And make sure it’s not sized higher than the wire size you are using.
Hey there! Thanks for the heads up and the advice! *I'll definitely pass your message onto Danny*. Keep those tips coming, and thanks for being part of our journey! 💜🥰
@@the.vandersonsThere is a lot of fearmongering from folks who don't understand the theory and haven't tested in real life.
1. Your PM has either a 180A (stock) or 220A (optional) alt. The PM alts have proven to be robust when tasked with heavy house battery charging.
2. I've collected data on 40+ setups where the alt is used to charge LFP directly. The average *max* current observed is 0.29C, which would be 116A in your case. But...
3. Perhaps counterintuitively the data reveals that the C-rate tends to decrease as banks get larger. There are 5 vans with 400Ah setups in the dataset; they average 0.2C, or 80.8A *max*. Highest observed was 0.24C, or 94A.
4. charge acceptance at middling or higher states of charge are much lower, as with the 20A you observed when the bank was closer to 90%.
The Promasters in the dataset (all bank sizes) have handled up to 120A charging with the stock 180A alt for years, and 160A for the 220A HD alternator.
IMO a DC-DC is not required in this case. I /would/ add a switch on the VSR's ground wire to deactivate it at will. I usually charge only when driving and disable my VSR around 13.7v -- solar finishes up after the heavy lifting has been done.
I have no idea what you're talking about!! LOL. But it's all good. I can't wait until you take off again!
Saludos from Guatemala, remember you guys from the shop,been following your al the way down.
Hey Carlos! *So* great to hear from you! _Absolutely_, we remember the shop in Guatemala. Those were some amazing times! Thanks a bunch for sticking with us on our journey down. 🥰💜
I like this video. Danny you are truly a star performer! Hope the new batteries are good to you both.
Love your videos so infomative. You and Emily make such a good team together. ❤
Awesome. I learned by watching.
Great progress! You’ve taught me so much in just a few minutes! You two are such a great team! Oh, and I didn’t miss that Graham helped with the unboxing! 😂. Looking forward to the next episode! ✌️❤️🚐
@msvg3, _Thank you so much_! Danny and I are super glad to hear you're finding the videos helpful! ✌️💜🥰🚐
Thanks for the great tips on upgrading to Lithium battery technology! I’m sure it will help others with their construction. Can’t wait to see the new solar panels video! Nice Job! 🎉😊❤
Hey Andy! *So glad* you found the battery upgrade tips helpful! 😊 Thanks for the love and support, it means the world to us! 🎉💜🥰
Awesome. Thanks for explaining. I’m in a cabin off grid and will be installing solar at some point. Good tips! Great job ☺️
@HillabillyHippie That sounds like an amazing adventure, living off-grid in a cabin! 🥰 I'm so glad you found the solar tips helpful! 💜✨
Ok I just shared!!!!!!!!!
💡👍Brilliant !!
💜🥰
The relatively low current flowing through the VSR is likely due to the bank's high state of charge. Having the NEG return through the chassis does help control current, but I suspect you'd see a much higher draw at 30% SoC or whatever.
I put an on/off switch on the ground wire of my VSR to keep it from getting "stuck" because of LFP's higher resting voltage. Also allows disabling the VSR if you don't want to run it. Easier than accessing and tripping the breaker. My switch is accessible from the driver's seat so it can be done while driving.
I’ve made a note to consider adding a switch for our VSR once we’re reunited with our van. Safe travels on your adventures and happy van-life tinkering! 💜🚐
Can you tell me about the adhesive closed cell foam used to insulate or where I can find more info on it? Do you know what the r value is? Thanks!
Great job. I'm curious, don't you need airflow around batteries in hot weather?
Danny, I went from a Renogy MPPT to a Victron MPPT and it upped my solar input and doubled it, I have 400 W of solar on my van with the energy. It was pulling in about 135 and with the Victron, it pulled in 285

Wanted to warn you about that charge controller. It will charge the batteries one time just fine. Mine which looks like the same model but may not be...will charge the batteries and then say FULL on the screen. From that point on the batteries will discharge all the way and the charger will never come back on. Just FYI. Also you may want a temperature controller and silicone heating mats to keep the batteries warm during the day when solar is working. Not that 400 watts will really put a lot of current in them, but unless they have heating, damage might occur at temps below 5C. Also a blanket or some form of insulation on top might help if they are being heated. Otherwise if you are using a diesel heater or something not covering them might be better.
The charge controller I was talking about was the AC powered one you showed briefly. The charger...
@@allynonderdonk7577 Hey @allynonderdonk7577! *Thanks* for bringing that up! 💜🥰 Keep on powering your adventures!
The problem with a direct alternator connection is you can blow your alternator. Honestly, its not worth the risk, at some point it will blow.
