• Charge LiPo batteries "in a fire-retardant/fireproof container… on a non-flammable surface, such as concrete." — Traxxas, LiPo Batteries
• "Never leave charging or discharging Batteries unattended" and never leave them "charging or discharging overnight." — Horizon Hobby lithium battery safety sheet (PDF)
• Use a LiPo-specific charger, and "NEVER charge a LiPo battery using a NiMH charger." — Traxxas, Battery Basics
• "LiPo batteries should be stored at 50% capacity." — Traxxas
• If a battery gets damaged, hot, or starts to swell, stop charging and stop using it. — Horizon Hobby safety sheet
