A long time ago I settled on an SLA battery + inverter in a backpack. Then you just plug in whatever equipment you need into the inverter.
It’s not as light and slick as some of the other ideas out there, but there’s not much you can’t plug into an inverter. Or get a Tycon PoE with 12V DC input. Lighter than an inverter, and still going to power almost anything you have. https://www.tyconsystems.com/tp-dc-1256gd-bt Keep the inverter around for those occasions when you have something that isn’t PoE. And get a set of inverter cables with alligator clamps so you can run off of your vehicle’s battery.

No the BN cannot accept PoE as your observations are correct, the power requirements exceed the safe capacity of CATx cable. All cables into the BN connect through Harding brand connectors. The BN can however negotiate down to 1 gig eth. The SOB project has hit another snag with powering the BNs in that the battery we’re using can’t support that much wattage either; it tops out at ~75 watts. The present SOB build is powering RNs (over PoE 40+ watts) and works well. Looks like we’ll be making something specific to battery power the BN instead of having a one-device does all solution.

I’d be very interested to see your upcoming product. >From what you’re describing the 802.3BT standard will work fine for a Tarana RN, but would be insufficient to power a Tarana BN. Also keep in mind that both the RN and BNs will require a gig eth port or higher as they cannot negotiate to anything lower. Incidentally, I learned yesterday that Tarana is developing their own survey tool and accompanying app that they hope to release Q2. I’ve attached a PDF with some brief details. Incidentally, on the SOB we’ve scripted the mAP to parse IP neighbors and its ARP table, create a static dns, and then dst nat that discovered IP. This makes managing whatever device is plugged into the SOB, regardless of manufacture, provisioned, or defaulted, easily accessible through a .local URL. The field tech doesn’t need to remember default IPs or mess around with subnets etc., just browse to the .local URL from their device and they’re in. I’ve never used a PowerLink device, so you may already be doing something like this- but we think it’s a cool feature.

So I don’t know what you are talking about requiring 350 watts. Maybe that may be the max POE out budget of a small switch, but still. We are still in development for a 802.3BT Type 3, device, we actually have the POE stuff done, just working on battery life and some extras that was requested. We are hoping by 2nd quarter this year we will have a PowerLink BT out that will do 802.3bt Type 3.
