vibration in a van

[c3auto]

hi all

Im looking for some best practice guide lines in terms of mounting the physical cells for anti-vibration in a van.
The cells I am using are the blue aluminium/plastic cased ones. My system would be a 8S2P 320ah 24v cell system.

In my van I have 1" polyiso floor with 1/4" plywood over the top. I was thinking of using a 3/8" closed cell foam sheet between the plywood floor and the plywood base of the lifepo4 battery pack for anti vibration. Is this a good idea? or possibly a bad idea?

I have some m8 anti vibration feet similar to these https://www.aliexpress.com/item/100...4!sea!AU!120920609&curPageLogUid=8Mrbnp0GHrmP but im not sure how much weight they could hold. 8 cells would be over 100lbs.

I will build 2x cradles for each 8S configuration and be clamping the battery cells with 4x threaded rod/nuts, 11/16" plywood ends, with 1/16" rubber in between each cell and the next ,as well as the cell and the plywood ends.


Thanks

I used 32 100aH cells for my 4 24V batteries. Large cells are not recommended. Each battery case built from 26ga sheet metal, lined with ceramic fiber matting, batteries set on two inches of fiberglass ductboard (get scrap from local HVAC guy), the entire electrical cabinet surrounded with 1/8” alum. All four batteries have 175A Anderson connector for quick removal out the side door. Smoke detector and halon fire extinguishing system at top of cabinet.

In my opinion, the rubber spacer between the cells is not needed. If you want something between the cells for electrical isolation, simple flexible cutting board material will work.

I have two 4s 280 Ah LiFePO4 batteries in my RV trailer. They have been in a compression fixture since 2020. I've had zero problems with them. They are on a "shelf" that is elevated off the floor of the RV. I used a sheet of ~1/8" foam under the batteries. But I used the foam for insulation, not vibration.

My camper sees a lot of rough BLM and Forest Service roads.

I mounted my two batteries on vibration dampers, this is in the back of a crew cab work truck. I drive a lot of rough dirt, gravel roads. About two years now with no issues. The cells are compressed at about 12 psi and have not moved or shifted even after hitting a few large pot holes at speed.
