   Greetings, dear All!I wonder if the following MBs got the same DC-DC onboard power module:
J1900DC-ITX
N3150DC-ITX
J3160DC-ITX
The 1st one is declared to have 9-19 V input, 2nd and 3rd  19 V only.
I have a strange feeling that all of them will work fine with 12-14 V Pb accu, but not for sure.
Please could some one clear this for me, but the other way then just pointing me to MB specifications/manuals?
I'm planning to build a linux box and powering it directly from UPS battery terminals in the future.
Thanks a lot in advance!
