Location: Mt. Zion, IL | what are the amp draw specs for each of those? That will help you find a battery with sufficient amp hours. example, 3 finders and 360 combined use X amps. take amp hours of the battery, and divide by amps. This will give you about the duration you will be able to power the items when the battery is new, but without any factor of safety. Most installers use somewhere around 25% more amp hours than the load requires. if 12 hours multiplied by 10 total amps yields 120 amp hours, you should buy a battery with 155 amp hours at a minimum.
Wire size will also play with amp draws of units. Run at least 10awg to each finder and network hub (not listed in your items, but likely utilized) and probably 6 or 8 to the 360 unit |
