You kindof have to have a battery float charged, otherwise it will self drain. But all you need to figure out which wire is positive/negative is a multi-meter- which are free at harbor freight. set it to resistance and place one probe on the outside of the dc plug, and the other on the wires- whichever wire has zero resistance is the negative. to double check the positive place the probe inside the dc plug (can be hard to do) and touch the wires- the zero resistance wire is now the positive.If I didn't need it to be float charged could I just cut the connector off the ecotech cable, put terminal connectors on and hook them to the battery. Also how would I be able to tell positive and negative on the cut cable?
Thanks

Thanks for the connector sizes @DBR_Reef !
I just finished my rendition of this. I do like how you have the battery sealed up, but my battery is well separated (behind a wall) so it wasn't necessary. I also threw in a voltage meter to monitor the remaining battery life as well as whether the trickle charger is functioning.
Cables from left to right:
Trickle charger
12v battery
Ecotech Output #1
Ecotech Output #2
The battery cable is short just so I could fit it into the photo. In use that cable will be 6ft, and screw directly to a 100ah deep cycle battery.
I am still waiting for the battery meter on mine, and should be done.
PeleusTech® Battery Charger, 12V...I have a bucket of those meters if you need one
What charger is that? I haven’t found any in that form factor on amazon. Would be perfect
PeleusTech® Battery Charger, 12V...
Oh darn, I was hoping it came standard with that DC 5.5*2.1 jack
Yeah, that one has to be modded.Oh darn, I was hoping it came standard with that DC 5.5*2.1 jack

Would you mind sharing some more details about your rendition? I'd love to try and mimic your design.
What details do you need? The jack connector sizes are on the first page of this thread. It is an off the shelf voltage meter and battery charger, and the vortech cables are from ecotech. Wiring is simple: all positives chained, all negatives chained.
