It's been a while but convert your watts into amps by dividing total watts (add up watts of the four strings) by voltage. This is your amp draw more or less.
For example, if you have lights that total 24 watts and four 1 1/2 volt batteries that total 6 volts, your amp draw is 4 amps. The same watts on a 12 volt battery would only draw 2 amps.
