What have I overlooked (Done Wrong)?

[T-Oliver]

It's a lovely day in Minnesota, so I decided to reintall the Epoch batteries.

 This is the wire arrangement that I came up with.  What could be improved or what is absolultly wrong?

Looks good to me! I moved our 6 AWG cables inside, but I do like the extra terminals you added. Only detail it's better to connect the + cables first and lastly connect the final ground. This way you cannot accidentally short the + while connecting. Not a change in wiring, just your order or assembly. You should add a heat shrink and optional wire loom to the main positive cable like you did the others.

Ours is very similar. Both arrangements work fine since the main positive is connected to one battery and the main negative is on the other.

Looks good! Sure wish I could fit 2x Epoch 300Ah into the Elite I battery tray...

Maybe someday Epoch will come out with a slightly smaller 200Ah Essentials battery such that 2 of them would fit side-by-side into the Elite I battery tray, and with no height issues.

All buttoned up, with the exception of the temperature sensing wire.

I got rid of all the split loom in battery compartment.

The Blue Sky Solar seems to remember it's settings, making it a good day!

This is as clean an installation as I've seen! 😂 Excellent work.

I didn't bother with a temp sensor wire. As per the Epoch manual:
Wide Temperature Range
Engineered to perform reliably across a broad temperature spectrum, it operates effectively from -20°C to 60°C (-4°F to 140°F).
Integrated Heating System
The built-in heating system enables charging in cold conditions, safeguarding the cells and ensuring battery efficiency in freezing temperatures.

But then again, we do not live in Minnesota (nor would plan a winter visit). 🤣

We will be traveling through your area this June though. Where we live and travel, we could never possibly be outside of this very wide temperature range. You go Epoch!

The temperature sensor is scheduled for removal, as the BMS tells temperature.

The weather has been unpredictable this year (50s followed by 20 below zero.

The BMS does shut down in the cold, the batteries clicked off just as we got home from Florida.

Another way...I went with terminals on opposite ends.  No particularly good reason.

WOW!  

I've never actually seen RV antifreeze - FREEZE.  Nor do I want to ever see it freeze.

Very clean install, well done!
