Not sure I agree that all lipos puff if taken care of properly. I have quite a few going back a fair ways, the vast majority don't have any visible swelling or puffing. My take is over discharging is perhaps the most common contributor, and sitting charged too much.
Personally I can't see taking much of a chance, especially with a 9 year old being around or working on the car. Lipos are available pretty inexpensively if needed, and are consumables anyway.
