He already said it's 12 volt. But for sake of discussion most 24 volt and 36 volt units are either running multiple 12 volt batteries in series or running s special order battery in 24 or 36 volts. If it was a 24 volt battery I wouldn't use it. You can by a DC to dc converter or build your own step down unit but why spend the $$ on these inefficient ideas it's just not worth it
