Charging something big like an e-bike, scooter or power tool with a lithium-ion battery?

**** Via NS EMO Charging something big like an e-bike, scooter or power tool with a lithium-ion battery? Do it outside. Use a flat, dry area away from direct sunlight, anything wet, kids, or tripping hazards. And make sure your bike or device is secure - so it doesn't fall while charging.
