On a -7C pre-dawn drive in Spokane, my IBflex on a 12V LiFePO4 pack sagged to 10.3V during 60s VoLTE origination/30s idle loops and rebooted, leaving gaps in the RSRP/PCI timeline. What compact, low-noise DC-DC or field-proven pack are you using to keep the scanner isolated from the laptop so logs stay deterministic and the KPI run doesn’t get compromised?
Saw the same with IBflex rebooting at about 10.3V around -7°C; an isolated buck-boost fixed it. > you using to keep the scanner isolated from the laptop so logs stay deterministic and Agree on the timing part — Traco THN 15-1212WI (9–36V→12V/1.25A, about 75 mVpp) fed by 4S LiFePO4 with a 10F input supercap and ferrite + 470uF on the output kept the PCI/RSRP line solid; if your VoLTE loop peaks higher, step up to THN 30-1212WI — what’s your peak draw?
