make an external battery supply for a Garmin?
I have an edge but want to get over 24 hrs from it, is it possible to use either a Li-ion or rechargable AA type thing, wired up to a micro usb connector? The unit works whilst plugged into a charger/PC so i would have thought it is possible..but I'm a nupty so what do i know?
cheers

I'm such a numpty i can't even spell it!
Cheers snaps, looks like it is do-able but i don't think they would last long, duck taped to my bars!

I built an external Li-Ion Battery for my E-trex Legend that lasted for days! but I drilled a small hole into the empty battery case and just soldered wires onto the pos and neg battery terminals inside. This also resolved it occasionally switching off mid ride.

To do your's & others i'd need to know the wiring configuration of the connector first.

find this though replacing garmin battery so you could possibly fit a bigger capacity battery inside
