2s LVP would be available after flashing with a different firmware. RMM offers this service; it’s also possible for you to do this yourself. Hoop - Guide: how to flash a NANJG / Qlite driver with custom firmware
Other options:
- led4power - LD-2 : 6Amps pwm-less linear driver - info and FAQ thread
- Many buck drivers based on QX9920 should handle 2s powering an MT-G2. Some of them have LVP.
- The current-version LD-29 buck driver (available from FT/MTN and probably others) can provide 3A output and should work with those input and output voltages, although I haven’t seen any tests of this version in this configuration. It’s got LVP.
EDIT: Added strike-through; see post #10.
