so im thinking about buying a couple cheap work lights to try out. i found the ones im getting there 350 watts. my question is can i cut the plug off and rewire them to use on batteries? ill probably only be getting two or three. and have four batteries so thats not a problem. do you think it can be done and still give me a decent amount of time on the water? i would just get a geny but im not allowed to run one at the lake. thanks.
