I thought I read somewhere on the GoPro site that the NimH rechargeable batteries that they recommend are about 900mAh.

I had my GoPro HD record 2 and a half hours no problem with the rechargeable it comes with  .

This should do it. I says 2A and adjustable voltage.

Can your GoPro be recharged with the usb cable? if so can't you use a car phone charger with usb connection?
On my 748 I had my MiniDV camcorder on the bike but battery would die to often. So this is what I did went to Radio Shack and picked up
a connector that hooked up to the plug for my battery tender. Also got a cigarette extention cord and cut the end off and soldiered on the plug for the battery tender. and plugged a small power converter in and plugged my camcorder in and had constant power to camera from now on. Since then I've upgraded to a Vholdr ContourHD 1080p but am in the process of doing the same on that seeing I only get just under 3 hrs of charge and luck would have it the only way you can charge and record at the same time is to use a cigarette lighter charger

Aflac, thats exactly what im trying to get to.

and mookie how the hell are you getting that many hours? i have 900mAh Energizer rechargables and those last 20minutes for me. the $5.99 AAA Lithium 1 time use ones last the full 2-3 hours on my bike on a nice warm day.

My go pro DOES NOT charge via USB. if it did that would be great. Thats why i was thinking of just feeding it a constant power supply from my bike, but it would have to directly into the battery well.


Mookie, that looks perfect. cheap enough for me to disamentle and rebuild into something roadworthy

I have the HD one. it comes with the battery. I`ve used it for 4 or five hours snowboarding with it on and off of standby.

I`m sure you can set up something good with it. Maybe put the transformer under your seat or hide it in the side panel.

He Man. I got temporary solution for ya not water proof though... They sell a variable voltage charger at Radio Shack just cut the end off and soldier it on your connection in the camera. The min voltage is 3 volts don't know if this will help you... (edit) be very careful you get the polarity correct the battery should show which side is positive and the charger shows the same wether the center pin is positive or not. When you cut the plug off leave about 6" this way you can use your VOM meter to see which wire goes to the center pin ie: black w/white stripe or black.
