You will need one of these from the store.

power plug

You can remove the plug from the large black and red wires on the battery by cutting the wires (one at a time) and stripping the insulation back on them. Place the Black wire in the new plug marked as - and the red wire in the new plug marked as +.

But is there a input on the EZ-b v4 Board for these power plug?

I think there is a red T-Plug DEAN...

you will also need the power base it has a 20amp fuse inside https://synthiam.com/Shop/AccessoriesDetails.aspx?prevCat=103&productNumber=1356 I use a six body as a desk top base because it has a lipo and fuse inside https://synthiam.com/Shop/AccessoriesDetails.aspx?prevCat=104&productNumber=1501

Okay, but I don't want to buy the power base :-D

Is it possible to tinker it? With these T plugs DEAN for example?

If you don't want to buy a power base or don't have the room in your robot for the extra height you can ad a piggy tail Power cord. Just desolder the dean's pin and solder on two wires of the length you want and add a Molex or other type of connecter of your choice to the ends.

sure it depends on your own skills just don't forget to add a 20amp fuse in-between lipo and EZB

Oh, thx.. bborastero....

The soldering (LiPo / T Plugs DEAN) is no problem for me... ... but I need a 20amp fuse? But where I have to soldering the 20amp fuse?

between the battery positive and the positive of the EZB
