Does anyone know of spacers similar to these but don’t leave gaps between the cells? http://www.ebay.com/itm/10pc-Battery-Spacer-3x-18650-Radiating-Shell-EV-Battery-Pack-Plastic-Heat-Holder-/321114252941
I’ve built a 10s4p pack which is currently glued into two parallel rows of 20 cells similar to the space cell pro 4 but because my cells are all hot glued together and soldered via fuse wires as opposed to all being spot welded together, riding on really rough roads can sometimes cause the glue to unstick between the cells which isn’t ideal. I used to use spacers similar to the ones I’ve linked but now that I’ve upgraded my pack from 30 to 40 cells, I no longer have the room to use these.
I’m also using Enertion’s space cell enclosure which has ribs along the bottom where the batteries sit which makes it more difficult to secure the cells with spacers but I’m considering sanding down the ribs so the bottom of the inside of the enclosure is flat as the ribs just seem to make it troublesome to secure the cells more than anything.
