Dual lithium battery case for 166FBS

[Forester2]

Made this to hold two Battleborn 100 amp batteries. Used 1 1/2" aluminum angle and fluted polyproylene. Strong and light.

That’s a cool idea, it gives me an idea for something I’m working on. I’m planning on installing my golf cart batteries under the RV to lighten up some of the tongue weight. I’m planning on doing 4 of them until I can do lithium. Awesome job.

[Forester2]

Thats the other thing I like on the lithium; very light weight!

My son-in-law is changing to lithium on his popup. No where to put it in inside. I thought of buying a heavy duty tool box that has a sealed lid and putting it on the tongue. Just to keep it safe from elements and not obvious as a battery worth stealing. I may put a hold down strap over it and bolt it on the bottom just in case.
PS love that Renogy bluetooth!. Put on the furnace 4.68 amps draw. Lights 1.6 amps draw. 91% left on my phone app. in seconds and no menus to look up.

I looked at that but between the curve on the front wall of my camper and placement of propane tanks there was no room. Box had to fit down in frame rails to get heigth for battery and to open lid.

Nice work!

What are the dimensions of this box, forester? Looks nice. Particularly wondering how tall you made it. Thanks!

[Forester2]

Ill get them tomorrow. Fit in factory battery area after nipping two front corners

[Forester2]

Outside dimensions are 8 5/8w x 26 1/4L x 10 1/2h. Fits 2- 100amp Battleborn batteries

Thanks so much. My angle iron holding my current battery is only 8 3/16” wide so I’ll have to make mine a little narrower. I appreciate you taking the time to measure it!

[Forester2]

Mount on top of angle. Narrower would make too tight a fit for my batteries. Also notch front 2 corners of box to move a tiny bit further forward to the tongue to allow better top clearance

[BillFuller3]

Im getting two renogy 100ah to put in the box. I think they are a tad smaller than yours, but after thinking more about, im going to mount on top of the angle iron too. Just won’t have to worry about things being too tight. I appreciate your help!

[Forester2]

If you run extra wires for battery usage at the box (suitcase solar, etc) or a battery monitor shunt, you'll appreciate some extra room.

[Jwhitebird]

Do those lithium require a specific solar panel up top?

[Forester2]

No but you set controller for lithium

[RogerR]

As a way to start understanding I like this short and simple youtube. It doesn't go way into detail but gives an understanding of how to install and run solar. If you decide to go solar than you can do more research on ideas and ways you can follow.

I do like and personally bought a Renogy system and battery when I installed. I like their US presence and warranty vs. some who knows from Amazon or Ebay. If you do go Renogy get a referral for an extra discount.

How do it know?
The GoPower panel indicates charge for battery A and battery B. But the wiring is just one line going to the battery box. In my case I currently have 2 group 27 lead acid batteries wired in parallel. GoPower sees them as just one battery.
I want to switch to lifepo4. Is there anything wrong in wiring the new batteries in parallel also? Since there is just one 'run' connecting both it will still be okay? And, has anyone done a project so that GoPower sees two individual batteries?

[RogerR]

I have no idea but Renogy batteries report there status by bluetooth so you always know the status. I know you can run up to 4 or 5 in parallel with no problems. The BMS seems to figure it all out. With lead batteries not so much.

You might call Renogy and ask these same questions for a specific and informed answer.

[Forester2]

I would think you would ONLY want to wire batteries in parellel to maintain 12 volt output assuming you are buying 12 volt batteries
