Alright electrical-gurus, I need some help trying to figure something out in my truck. To preface this, my 923 has an industrial lift-gate installed on the back of the bed. It has been working (has worked) in the past until I removed the aux-battery from the aft-tool-box (to install tooling in there). This disabled the lift-gate operation, until I can reinstall the aux-battery in another location.
Looking over the entire system to get it back in operation, I have some concerns / questions. Maybe I'm just overthinking this, but I want it to be correct / safe, and more specifically, I don't want it damaging the trucks main electrical system. I don't use the lift-gate for anything outside of occasional purposes, so it's not considered high-priority but when I do get it working again I want it to be correct (if not already).
Below are two diagrams I made, one is the Basic-Elec Layout that I have running four 6TL batteries. The pic on the right is how the lift-gate electrical portion is (currently) hooked up to that system (with the exception that originally the converter 24v (+) input line was connected to the #4 battery (+) terminal, since then I moved it to the Kill-Switch so that the 24v/12v converter would not be powered unless the K-S was disengaged, but the aux battery is also removed at this time too so the converter is inop anyway)
My question is, do I need a DC to DC battery charge limiter / battery charger anywhere in the system? In between the converter and the Aux battery? Or is the Aux battery maintained by the constant flow of 13.3v to it? My gut tells me something is not 100% correct in this setup, even though it works. All comments/criticisms welcomed, please help me understand, I'm not too good with electrical, but I can make diagrams I guess lol. How are you guys running a 12v Aux battery in your truck?
Thanks in advance![Folded hands :pray: 🙏](https://cdn.jsdelivr.net/gh/joypixels/emoji-assets@5.0/png/64/1f64f.png)
