Did you blow the on-board fuse?

Edit:  The DNA 200 doesn't have reverse battery polarity protection, so probably blew the fuse when wired backwards...

Yes, it looking like you picture

SO have any way to fix it. 

Could i remove this inductor and connect them directly

You don't want to connect them directly because that is protecting the batteries & board from short circuits...if you have enough room, you can wire in a mini automotive 25 amp fuse...and tuck it away somewhere inside the mod...
