What uses a 24V battery?
What uses a 24V battery? We sometimes use 24V battery systems in larger trucks and busses due to the vehicle's higher power needs and long cable runs. You can also see 24V used in larger boats and some RVs with elaborate solar systems. Another typical application for a 24V system is on trolling motors for fishing boats.
What happens if you put a 24 volt battery in a 12 volt car?
It might seem like the obvious answer is yes, but unfortunately, it's not advised. 24-volt batteries typically have twice as many cells as 12-volt batteries, meaning that you will need at least two 12 volt batteries to power your car instead of one 12 volt battery.
What happens if you put a 24 volt battery on a 12 volt motor?
24v hooked to 12v will spin for a while on a full battery but there will be no torque. You could stop it with your hand. It is like running your motor with half the spark plugs missing.
