Thanks for your reply post skeasor,

Unfortunately, I did not have my smart-phone or a camera with me at the time, as I had only gone out to my 'Test Track' on a friends
farm to 'fine tune' both my buggies, so that they would be good and ready for when my local club opens it's newly refurbished track and facilities.

I was also going to return to my OP here this evening to declare the bulbous LiPo pack is "Now truly Dead and made Inert' and that the post-mortem
revealed a 'microscopic' pinhole that may have been caused by our infamous 'Goathead' bindi that proliferate the farm.

So the new hard cased LiPo packs are now mounted high up in the starter box,
just so they are well clear of such nasties if using the box on the ground again.

Still curious as to what the 'liquid' was though
