Thanks for the responses. We tried a few different batteries and only one of them actually worked, which seemed weird. Then we opened up the cRIO and found lots of metal shavings, which obviously should not be there. So we blew those out and put it back together and it works fine now. Now my only question is why did one of the batteries worked while the others didn't? edit: All the batteries were charged, except the one that worked was at about 10.8 volts
