It might be possible with upsrw - try modifying "input.transfer.low" and "input.transfer.boost.low". However, 40V to 110-120V is a long way to boost. Is this UPS rated for such a wide voltage range? You could also check for sensitivity settings. I don't know about the 3S in particular, but theoretically, usbhid-ups supports those sorts of settings. -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsdev mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsdev
