Recently I fried my Ping bms inside my Arkel tailrider, by packing yellow camping foam too closely to the BMS. The problem is getting waterproof containment of the battery with good padding, but allowing the BMS to breathe and not using a heavy can - versatility of attaching tailpacks to multiple bikes seems like a good idea except for my disastrous experience.
Apparently the Ping needs 2 cm. of air space above it. I found that if I wrapped a non-leaking 20" bycycle inner tube around the ping (48V 15Ahr) it would go around three times and stay on. When the inner tube is inflated it leads to a "bounceable" ping, with lots of space for the BMS to be exposed to air. This seems like a good way of padding a ping inside a bag or a box - there is minimal contact of the padding surface, in this case a rubber inner tube with half inch contact patch, with the battery or BMS, and is very good at absorbing shocks, depending on how much air is put into the inner tube. It also takes up slack in the Arkel tail pack nicely.
Between "Headway condoms" and "Ping pads", inner tubes are a greatly neglected resource. What else are they good for?

I glued some on to the plastic tires of my kids ride on toys. Makes pushing them smoother and quieter. If I ever diy a battery enclosure I'll def use some, at least some bad ones glued on as non-conductive shock-absorbing lining.. Or maybe even inflated up like you say.
