Err - are you sure about that? If true, yowsa, that's a lot!RNM said:Mineral oil is a good idea except that it would need 100~200 liters, since there's so much free space inside the pack

I saw on a mineral oil cooled PC site that STEOil makes "tech-ready" (Electronics safe) mineral oil, and sell it in rather large quantities.
"Crystal Plus Tech Grade Mineral Oil 70T - 5 gal"

I was hoping one or two would do the trick. If it'd really take 10 of those, then ouch - that's nearly $1000 in mineral oil!
I see they offer it by the 55 gallon drum, though, and you have to call in for a quote. I just did, but it still came in over $500 before shipping. :lol: I have a feeling that if anywhere near 200 litres is required, it's going to make more sense to just save up for a new battery pack. (They'll drop in price within a few years, once Tesla is mass producing lithium ion batteries.)
Does anyone know how well the battery packs are sealed? It appears that if filling it up fully, a lot of oil would be in touch with the seal, and be located above it. Just wondering whether this idea would turn into a huge mess.
And to fill it up, the cover itself would have to be modded to include a sealable opening on top?
