Rick: 5 gpm=0.315 liter/sec BUT we need the head ( vertical distance from the spring exit to the end of the pipe) -- and the length of the pipe and the diameter -- maybe the end pressure of the water if the pipe is closed.
Example head of 10 meters =32.8 feet gives around 15 to 18 watts of energy or 0.360 to 0.430 KWhour. If you do not have enough time to charge the batteries, may what you need is a higher power charger. Can you define the capacity of your battery bank (amp hour) and the voltage ?
