I think there really isn't any getting around the issue of the external
battery charging the internal one. It's not effecient, but with out
modifying the iPaq its self I don't see a way around it. I have the same
problem with my laptop when using the external battery.
One of the things I have to test is how will the iPaq respond to the battery.
It will think it's a charger, but at a point the power from the external
battery drops below what the iPaq can use what will happen? On older laptops
I have played with the external battery then begins placing a load on the
internal batteries (this can be fixed with a diod I believe) on newer laptops
the laptop just stops using the external power source when it drops to low.
Like I said, I'm going to have to test and see what happens. As for how much
the external battery has been used, there are ways but it will make it harder
to build (esp by hand).
My friend has a thought of this a while ago. I assume the external
