I hope that Mac OS X turns off write caches on low battery.
 

I've never heard of such a thing.  The best you can do is try to push the system into hibernation instead of going down hard.  That *should* clear any disk caches as part of the graceful shutdown.  But you're relying on a relatively fragile system now, once the battery is quite low who knows if that will even execute in the window of time you have left.
