Hi, I am buying a 40W solar panel to charge my mobiles and ipads and making a solar charging station. is this battery enough to support 4 items?

Question

Accepted Answer

Believe it or not, I use the batteries (two of them) in an old flymo RC320 24 volt lawnmower, which manages our 6m x20m lawn and a bit over before dropping below a viable power output. It doesn't say anywhere I can see on the machine or the paperwork what the wattage of the motor is, so I can't help you with any figures, other than to say that the 24v charger puts 280ma into the pair of them, ie 14ma each, so that is presumably the optimum input for them.. I recognised the batteries as those we used to have in the emergency lighting system in the office where I worked. I have found them to be the most durable available at the price! Sounds likely to be a good storage unit for the low power rated stuff you are proposing to connect to it.
