I have a 40 with some accessories on my battery setup (1 battery, top terminal post design). I am officially running out of room to safely keep the accessory wires neat and tidy.

I have seen the cheap "distribution block bus bars" that you mount on a flat surface (not a fan of the design). And I have seen simpler designs like the Moroso battery terminal block kit that is simply a terminal block that allows you to safely add additional power leads with terminal crimps.

What are you using and any advice is greatly appreciated.
 
Powerwerx sells a few difference options. I've used their stuff for going on 10-15 years and they've been great
 
I'm using the SDHQ as it accepts the OEM harness on my 2018 LC.
Other brands I looked at were SLEE and Stinger.

I am, obviously, not much for keeping things neat and tidy, or much of an electrical anything so I'm using a cheap "distribution block bus bars" that I mounted to a flat surface. I used to have 6 or 7 wires going to my hot battery posts, now they're mostly tucked back in a corner out of the way. Maybe not a great design but better than it was. I don't bother with the black bus bar though.

Good lord!!
 
A decent clamp on the battery with the main feeds coming off it. Fuses as appropriate. This is my main. The aux is a lifepo4 and has fused runs to accessories and to a fuse distribution box in the engine bay. Most of the accessory stuff like the HAM, OBA and additional outlets in the front and rear of the 80 feed from the lifepo4.

cheers,
george.

^ good spotting. A perfectly installed 'wedge' since the original bit of plastic went awol and been to lazy to 3d print a 'proper' solution :) Not nearly as elegant as pighead's plywood...

Before I changed the battery clamping setup (toyota really screwed that up on the 80), the stupid hooks were destroying the slots in the fiberglass on rough roads and I had to 'stabilize' the battery while on a couple of week trip in death valley... The 2nd picture is for you discerning eye - use of wood again :hillbilly:

cheers,
george.

@ George_tlc . Orange battery is the LIFEPO4? Mounted in engine bay? Any issues with heat?

Yes, the black battery with the orange label is the lifepo4. It is charged by the Wagan DC DC charger with lifepo4 profile. Lifepo4 batteries are stable and safe and their operating temperature range is at least as good as lead acid batteries. Additionally (unlike a lead acid battery) they have a BMS inside that protects the battery and among other things will ensure that the temperature is in the right range to enable charging and discharging to occur. It is an ecoworthy 100ah battery and the specs make it safe for operating in the engine bay. The 80 has nice battery cases in the front of the engine bay that create a cooler operating area.

cheers,
george.
 
@ George_tlc. I have a LIFEPO4 installed in the engine bay. I don't have an 80 so I built my own heat/water/ muck shield. I installed a little cooling fan in it as well. Just monitoring what others have experienced with Lifepo4 batteries in the engine bay. Trying not to take up space in the truck bed, which I use for other things. My setup seems fine so far, but have not tested in California type temperatures.
 
I use 285 Series breakers right at the battery unless fusible links are the better call. The output stud on the breaker makes a pretty good place to tag in the various consumer feeds. If I need more room than that I use an isolated stud from the cowl of a Square Body GM truck. I've only ever used a bus bar to tie together the input power to a series of klixon breakers.

Fusible links are all on a terminal strip where they're easily replaced with a spare (which are located on unused terminals) using a screw driver.
