As a general rule check the easiest things to fix first. Always. That said I would bet a buck you have a loose connection. If the batteries are deep cycle do NOT use a load tester. They are for cranking batteries not deep cycles and could harm them. To check a deep cycle get a digital voltmeter and check the voltage. There should be instructions that come with it to tell you how to do it. Fully charged deep cycles are going to read at least 12.8 volts. The should hold this level for weeks or longer. A bad one will drop at least .3 volts overnight.
Before you do anything else run it as you usually would. Then feel all the connections but carefully. A bad connection will be warm if not hot.
I’ve been playing with these things for many years. Over 90% of my problems were bad connections.
Good luck.
