Lipo fires are overhyped.
A lot of the fires were deliberately staged (Utube) for one reason or another. The lipo material itself is way safter today then a few years ago. Most probs or incidents happen while charging and are typically user error - charging as the wrong chemistry, not hooking up balance wires, going off and leaving it unattended etc.
Get educated about lipo, use them kinowledgeably and respectfully and you'll prob never have a prob.
