House battery install... yes, another thread

Preamble:

Thanks to all TW members; did a lot of reading, asked a lot questions and looked and thousands of pictures here.

The second battery (“house”) is intended to mainly be used while camping to charge phone, charge portable speaker, USB fan, run air mattress pump, inside camper shell LED lights, driver OR passenger side outside LED lights, front OR rear outside LED lights.

All LED lights and low amperage. The outside LED lights will be used for outside illumination (obviously) to set up camp if you arrive late or if you need to getup in the middle of the night or need a bit of extra light while cooking or something.

Main components I bought (all from Amazon), in addition to electrical cable and electric consumables:

Battery:Mighty Max Batteries ML35-12GEL 12 volt 35 Ah

Isolator: True Smart Isolator

$81 VSR12 12V Dual Battery 140A Smart Isolator (VSR Voltage Sensitive Relay) for Auto/Boat/RV

VSR12

Inline fuses: Buwico inline circuit breaker fuses: 50amp and 40amp

Switch & Outlet Panel: Cllena Dual USB Socket Charger 2.1A&2.1A + LED Voltmeter + 12V Power Outlet + 5 Gang ON-OFF Toggle Switch

Blade Fuse Block Box Holder 12 Way With LED Indicator for Blown Fuse.

4 gauge battery cables.

The basics:

The actual house battery installation is not the prettiest of the bunch but, simple and practical for my needs.

Inline 50 amp fuse from starter battery to isolator to house battery to 40 amp fuse to fuse block.

For easier troubleshooting I decided to run individual power lines to each accessory to the Switch & Outlet Panel (don’t ask why, my preference).

Made a wire harness from the fuse block to the Switch & Outlet Panel... IN THE BED. Run the wire harness under the truck along the bed frame.

Removed bed cubbyhole on passenger side; just above it I cut a hole on the bed to install the Switch & Outlet Panel.

Ran load wires to each accessory, remember to ground all accessories.

Tested all accessories & all works as planned.

I need to do some clean up today, cutting a hole in the composite bed was messy.

Only took a few pics

 

Nice.
