Yale walkie stacker comes with battery and charger it also comes with a second battery case to install 4 car batteries if the main battery ever goes bad. It plugs into a standard wall outlet to charge. Lift capacity is 3,800lbs and reaches 10.84 ft. It does also have side shift. I have the key switch jumped because I got it with no keys I orderer Yale keys but they didnt work so I bypassed the key. Easy fix with a new key switch if you need it. Need a trailer that drops to the ground for easy loading. Any angle this will get stuck as it sits close to the ground unless you have a winch and a slight angle could be loaded with another forklift.
