Electrical safety engineering: dissecting UL 2271 battery pack and UL 2849 complete electrical drive system fire-safety and thermal runaway standards.

Containment engineering: Modifying military steel ammo cans, PyroBubbles fireproof media, and smart smoke-cutoff relays.

The electronic brain of lithium batteries: Over-voltage protection, low-voltage cutoffs, and passive bleed balancing.

Preserving capacity in off-season: Storing at 50%-60% charge, room temperature storage, and avoiding parasitic BMS drain.

Fire prevention engineering: UL 2849 vs UL 2271 certifications, thermal runaway mechanics, and safe indoor charging protocols.
