I've been on the fence about purchasing a few pieces of lithium-ion-powered equipment. I use an open utility trailer so all of my equipment is exposed to the elements 24-7. Gas-powered equipment holds up fine to these conditions, but what about li-ion? Can the equipment/batteries handle constant UV rays, high heat/humidity, extreme cold, heavy rain, sleet, and still perform reliably like gas-powered items day in and day out for years? Stored in a garage, they'll last for years, but what about real-world conditions like I just stated?
