Just wondering if there is any interest or if I should drop this one. Battery backup + PSU + POE switch

Form factor
- 10" rack, 2U, ~245 mm deep
- Sized for short mini racks (~260 mm deep)
Battery
- 4S LiFePO4 prismatic cells, 12.8 V nominal, ~320 Wh
- Cells under compression in the pack
- Dedicated BMS with protection FETs, current sensing and per-cell temperature monitoring
- Steel barrier between the pack and the electronics
Power
- Internal 500 W-class AC/DC supply, 100–240 VAC, IEC inlet, fused and switched
- 24 V internal bus. Mains and battery feed it through ideal-diode ORing, so there's no transfer gap when mains drops
- Up to ~450 W continuous on mains; ~300 W continuous / 400 W peak on battery
- Estimated runtime: ~1 h @ 300 W, ~2.3 h @ 127 W, ~6 h @ 50 W, ~15 h @ 20 W
- Solar/DC input: 10–60 V, ~250–300 W MPPT
Outputs
- 5× USB-C PD, up to 100 W each, one converter per port
- Power goes out over USB-C PD and PoE only (no barrel or Molex outputs)
- Every power port can be switched on/off and power-cycled remotely, so you can hard-reset a hung SBC, router or AP
- Firmware power budget with per-port limits and priority load shedding
Networking
- Managed switch daughterboard
- 8× 2.5GbE with PoE+ (30 W/port, ~120–180 W total budget)
- 2× 10GbE SFP+
- Base unit ships without it (blank plate)
Management
- Onboard microcontroller
- Telemetry: battery state and temperatures, mains and solar status, per-port power, PoE, fan speed, fault log
- CAN / RS-485 expansion port, plus a front USB-C service port
- Front panel: status/charge LEDs and a power button
Cooling
- One 80 mm PWM exhaust fan at the rear
- Passive front intake with a dust filter
