Single 24v battery?

[majorhavoc67]

Just out of curiosity, does anyone know of a single 24v battery that would be enough to power the HMMWV? Just wondering if something that would fit exists?

4HN might work barely.

Maybe 4 of them

I believe that some helicopters use 24V batteries the same size as 6T, or something similar. I remember someone talking about snagging one from their flight maintenance unit after it aged out or something like that. Perfectly good still, but in a multi million dollar helicopter you don't take chances like that.

The question is, why would you want to?

About the only thing that using a single 24V battery would change is completely screwing you over if something happened to it, as opposed to only halfway screwing you over if one of the 2 12V batteries decided to fail completely. You'd also lose any chance of using a 12V vehicle to jump start your rig in that situation.

Look at it this way, with the military's pretty much unlimited budget, if there was a 24V battery that was better suited to this job than a pair of 12V batteries, they'd have probably switched over to it long ago.

last time I saw an actual 24v battery was from a site that restocked batteries for varying type of planes/helicopters (especially separate category for extra-rugged 'safety battery') but otherwise pretty much everyone else pretty much serial-wire two 12v's or four 6v's together to get the 24v they wanted [especially for pre-lithium golfkarts too]

That would not work if you have a 4 speed or had a dual voltage system and wanted to tap off some 12V for accessories, both of these require 12V batteires.
