Yup that's what happens when those types of batteries pop. Just like smart phone batteries, dare ya to stab one of those

Each 18650 cell has the power of a stick of dynamite. Most smaller electric vehicles need about 4000 of those or equivalent lithium-ion cells.

Newer Lithium iron phosphate batteries are way way safer but their cost is still on the high side.
