    Default how do i wire my solar panel to 2-6v batterys

    hi everyone, i have a game camera im trying to hook up and i want to use rechargeable batteries and a solar panel to keep it charged, now i bought all 6v 4.5Ah batteries and a 6v moultrie solar panel and when i got my game cameras i discovered the cameras were 12. so i can hook the batters in series keeping the amps down, but how do i hook up a 6v solar panel to this so it charges both evenly?

    thanks

    You are going to have to purchase another PV panel.

    Before you spend any more $, do you know the power requirements for your camera?
    Volts, amps (I guess we now know it's 12V)

    To run off solar, you need to mount the panels in a shade free area, even a small shadow, will inhibit any power production in a small system.

    You may be better off, buying a pair of 12V deep cycle batteries, and recharge one at home, and swap them out every week (or when they get low)

    Well it just says it a 12v camera. I have 8 solar panels for my cameras and 4 or 8 6volt batteries already. Do I need to hook 1-panel per battery or would hooking the baterys up in "parallel be better because then I can use 1panel but my amps will be higher and I risk smoking the camera or mayb that's not enough amps to fry them I don't know.

    Do they give any indication of what size of battery would run the camera for how long ? It'd be bad to build up a system, and then find out it's only 1/3 the size it should be. Sadly, you generally find out when the battery is destroyed from over discharge.

    Batteries in parallel. It's better to have 1 large battery, then 3 small ones in parallel.

    more batteries in parallel won't blow up the camera, any more than changing a 100w light bulb, to a 15 w light bulb . The camera only pulls as much current (amps) as it needs.

    Well the cameras take 6 C-batterys. I have 4 or 5 cameras so buying 10 deep cycle batterys isn't going to happen. Useing these 6v ones would of been perfect if the camers we 6v so now I need to make it work

    How long do they run on the C batteries ? (we can search the web and find out the capacity of an average alkaline C battery.[ 8 amp hours] ) Then we can guess how large of PV and battery we need.

    2 months is 1440 hours and 8 amps comes up with about 6mAh consumed a day. Almost nothing.

    So, you should be fine, hook 2, 6V batteries in series, you have 12V now

    Now, lets explore the panels a bit more, any labels or stickers on them ?

    Google that tonight, and see what info you can find about it, it may have blocking diodes already. Need Volts and Amps info
