It would be cheaper and easier to just buy four smaller batteries. In fact, you would need the same weight in 24 volt batteries as you would for 48 volts. The converter does not increase the power (watts) available, so to get 2000 watts at 48 volts you need 41.6 amps. To get the same 2000 watts at 24 volts you will need batteries capable of providing twice that, 83.3 amps!

Subject: [Electric Boats] 24V to 48V ??
I suspect the answer will be "no", but just thought I'd ask....I have a Torqeedo 4R that I'd like to try on a small boat. But I don't want to have to lug a 48V battery bank out there.Is there hefty DC-DC converter that will step up 24V to 48V at up to 2000W? (and that's not crazy expensive)This is just for an experiment - I realize there would be penalties - but it would be better than buying another Torqeedo (2R).Thanks,John
