I've got my four 272Ah cells and my JBD BMS. Have now completed the top-balance.
So it's time to do the final assembly of the pack.
I'm not short of space on the boat, the pack can go pretty much anywhere. Thinking of keeping it fairly central, not too low down and obviously not within the engine space.
I'm aware of the concerns over aluminium cased prismatic cells on boats. I have some sheets of stiff 5mm foam (it's actually sold as laminate flooring underlay) and I have made up a box from this material, with sheets between each cell, just to prevent any damage from the cells rubbing against one another. I was thinking of keeping this in place and adding the conventional end plates with threaded bar. But maybe I should have something a bit firmer between the cells?
I've also got an old safe box going spare, and I could mount the whole pack inside that. Snug but doable. This would make it easy to bolt down securely, and of course it would give some protection in the event of fire. But maybe I'm better off having the pack better ventilated? I also worry about the possibility of shorts, putting everything inside a steel box...
