Interested. PM sent.

https://powerwerx.com/tricrimp-powerpole-connector-crimping-tool This is the tool I use. It is not exactly cheap. I use PP for all my 12v connections, even many that do not strictly need a quick disconnect option. The Voltage drop is minimal. I use them on all my ham equipment, fridge...

Might it be easier to just mount an Anderson connector in the front bumper? And just run your cable from the controller to the connector in the bumper?

There are options: https://andersonconnect.com.au/store/index.php?main_page=product_info&products_id=317

Too long. It made me.

Loads I used a Powrwerx double connector panel mount. The easiest way to cut the hole is with a 1 1/8” hole bit. In this case because the plastic of the box is not that thick, if you do not have a hole bit you can mount the cover plate and use a razor knife to cut out the hole. I tend...

Arrangement There are a lot of priorities to consider when laying out the box contents. The primary challenge when trying to minimize the size of the box is finding enough real estate to on the walls to mount the panels for the power sources and charging ports. Panels are flush on the outside...

I worked extensively with @vomhorizon on this project, who offered me endless support for the build. I am writing this to pass it on. But...Disclaimer: I am a weekend warrior, NOT a professional in any way. Batteries can shock you and burn things down. Be careful. Do your own research regarding...

Since those two powerpole connectors will only be used for low current applications I daisy chained them together and they share a 20 amp fuse. In the pic of the front of the box you can see I have another set of powerpoles which serve as inputs for the DC/DC charger and solar charge...

Thanks. And thanks!

Yes. Exactly the same.

Thanks. It is a lot of connections and crimping etc. and I just wanted to make sure I didn't make a significant error along the way. Really appreciate the math check.

I have a small inverter with powerpole adapters. When I get off the phone here I will hook that up and rerun the voltage drop measurements.

DaveInDenver, you have correctly identified the system configuration. Thanks for helping out. As far as wire lengths: Positive Run: Battery Positive to Breaker: 8awg 14" Breaker to Fuse Block: 8awg 16" Fuse Block to power pole: 10awg 10" (including the three way splice) Negative Run: Battery...

I do not have any heavy loads right now. With a 3 amp load I see these results. Is this what you were referring to? 13.19v at the battery and 13.10 at the powerpole under (3 amp) load.

I just completed building a portable battery box. Obviously it involved creating a lot of spliced and terminal connections. I would like to go back with my multi meter and test those connections under load. Is there a standard protocol for this? I assume that measuring voltage drop is better...

Horizon, you are ahead of me. I still have not even picked a case. Just decided go move to lithium at the last minute when the lead acid batteries I was going to use turned out to be beyond repair. Great if you update the thread with your decisions/discoveries.

Thanks. That looks out of stock at the moment. I have been looking at the Bioenno offerings.

Also, if anyone has any recommendations for a simple "drop in" battery that would be great too.
