Afternoon peeps
I'm interested in buying a 10W LED floodlight (12v/24v) to run off a car/deep cycle battery.

I currently have a 60W spot light. Its like the ones you see on the roof of utility vans or land rovers - its round with a plastic mesh on it.
So if its 60W and runs from 12V does that mean it draws 5ah? the LED floodlight draws 900ma at 12V or 450ma at 24V.
If i linked to 12v batteries together in series it would give me 24V so the light would draw 450ma. So is that 225ma from each battery?
I know your only supposed to put batteries in series if they are the same age, condition and type. I have two leisure batteries that are the same but not quite in the same state. One charges to 13.24V and the other will fully charge to 12.82v. (which my charger class's as "weak" ??)
so.....i take it i shouldn't wire those two batteries in series? :o
Cheers
