This might present some issues for forcing charge in
through the croc clips.

There may also be some diodes in series to prevent "back" charging or to
prevent accidental damage when a 12V unit is connected to 24V.

They'd be some diodes to carry starter current. And the voltage drop
through those is something you don't want when jump starting under extreme
conditions.
