With a 1700mAh (optional) battery the BT-338 can run for 15 hours.(Via pocketpcthoughts )I'm currently shopping for a Bluetooth GPS receiver to go with my Treo 650 and this GlobalSat BT-338 is an interesting candidate. At $179.95, it is among the cheapest BT GPS units that can be found on the web.
Optionally, it is possible to buy a higher capacity battery to push the autonomy up to 15 hours, which should be sufficient for most tasks, even a fun hike. It comes with a leather case, the in-car charging cable (PDA+GPS), a 110/220V charger with many plugs adapters and a CD with software.
