car: thanks for the information. I have a few questions for you. What brand of batteries are you using? At 92%, have you checked the batteries with a digital meter to see what actual voltage you have? I have the M100 which is just a higher version than the M80. No M80 in stock at the dealer when I bought the M100. I tried rechargeable Energizer, tested 1.2 to 1.28 volt fresh out of the package. I can bump them up to 1.38 to 1.44 volt with the charger. At this reading the M100 only showed 64%. Using the Pure Energy rechargeables 1.55 volt out of the package, these showed 96% in the camera.
*Just checking the website you gave, that is a nice solar panel, larger than the ones that another dealer was selling here. This one has the 12 volt battery in the unit. It then should have the diode already installed in the system so it will not drain the battery at night.
The batteries I mention testing would be the batteries that you would have in the camera. You wouldn't need them with your system. Thanks.
