Custom Solar Battery Bank - DIY Sprinter Van Conversion #6
Вставка
- Опубліковано 23 жов 2018
- Welding the cage underneath the sprinter van in order to support all four of my Trojan T-105 batteries was pretty difficult. Initially I thought I would put the batteries towards the middle of the van but struggled to get them to fit. Ultimately I decided to put the batteries where the spare tire rack was, centered in the back of the van.
Even once I figured out where I was putting them it still took quite a bit of planning! Thankfully I got the battery cage all welded together and the battery rack is successfully installed under the van!!!
The total battery bank capacity is 450 amp hours at 12 volts. I used 4 Trojan T-105 6v golf cart batteries welded in series and parallel. All 2/0 stranded wire was used to wire in the batteries. There is a temperature sensor, voltage sensor, and shunt installed as well. All of the terminals received a healthy coat of terminal protector to keep it from corroding. Also, there is a Trojan battery watering system installed to each of the batteries... this means they can all be watered from one hose that is located in an easy to reach spot by the trailer hitch.
I am very happy now that these batteries are out of the inside of the van. It gives us a lot more room in the back of the camper van which is key for being able to fit our kayak and other toys in the back. We have travelled thousands of miles with the batteries as they are and have not experienced a single issue; it has been all around great!

Nice welding job!
Thanks!
Very cool. Thanks for posting...
Thanks for tuning in!
Thank you that's what I'm doing to my van now thank you sir
Good luck, a lot of work but absolutely worth it!
@@GetBusyBuilding indeed sir I'm ready
Very nice video. I like the narration and quality of your work.
Thank you, really appreciate the feedback. Not perfect by any means but it’s a learning process.
Great video! Can't believe you did all that in such tight quarters 😳
Nice job Bjorn! Inspiring me to get my welder out!
Gotta tellya pilgrim ..thats nothin short of a miricle .. fabbo ..😁
I wish this guy is my nextdoor neighbor1.
Wow great job
I removed my rear tire under my 99 Dodge Ram van, cut a 2ft 8 in wide by 2 ft long trap door, my van has an 8in lift so I was able to build the box about 20in deep. I have 4 6V 380Ah batteries for a 12V 760Ah battery bank, I had some fans I can manually turn on/off by switch and I had some custom louvers cut into the sides for air. I live in the Southwest side of the USA, temps get pretty hot here but Ive had no issues with my batteries. I charge my batteries using an off shore plug or my 3500Watt gas generator, I also have a 375 watt solar panel on top.
That sounds pretty epic! It’s always nice when the hard work withstands real life use, nice job 👍
@@GetBusyBuilding I like the way you did your batteries too, Ive asked around, I think we are the only 2 people doing it.
I haven’t come across anyone doing it this way either. I have seen some under carriage battery boxes sold for the newer sprinters that go on the drivers/passengers side between the two axles on the outer most portion of the undercarriage.... but they are expensive and it’s harder to get a battery bank with multiple batteries installed.
BearsBuilds I guess it’s like everything else in life, I was an engineer for over 20 years in the semiconductor industry. My job was to make the $20 million dollar pieces of equipment run our processes. We just never get complacent, always looking to improve. I have one of those cheap Chinese diesel heaters in my van, I installed a fuel cell under the van, the fill cap is next to my gas fill. I had to put a sticker on one of them because I forgot which was my gas.
Sounds like you have a very awesome rig! Definitely a labor of love!
I have sprinter van and i need somebody to do this job for me,btw I'm in Vegas.
That would be fun! I truly believe that going with some lithium batteries inside and having a light build would be a great route to go though and a lot less work!
How is this holding up?
Excellent!
Curious if you’ve had any issues with the batteries getting too cold on the outside. I’m looking at using Lithium batteries which may be more of an issue with freezing.
It would have to get fairly cold to have any real problems. I wouldn’t recommend snow contact by any means but I’ve used the system in snowy conditions, low 20’s F. I would personally put lithium ion inside the van just because they are simple and safe, they take minimal space. If you are set on an exterior case they are light enough to do quite a bit with and you can easily build an insulated box in a couple locations under the van that may have more room. Best of luck with your project, lithium is a great way to go!
