Stuck in Sandtraps Chapter

[captainhowdy300]

Hi............
Is there someone who can help me as i'm stuck in the beginning of the Sandtraps level...........
i've killed all the bastards but now i'm not able to take my car ahead as the road has been blocked by hurdles, and there is an electric cable that is extending from the nearby cabin......
in the cabin there is some sort of power equipment with three slots along with a battery that fits in either of these slots

i'm not able to find any other battery..........or some other method of crossing this shit, i have also attached screenshots...........

can someone help me get through this????????????????

there are 3 batteries. 2 are in that room, the other one... well, run around outside blasting everything with your gravity gun, you should find it.

it´s hidden quite obvious.

Looking out of the cabin window standing by the batteries, have a look in the engine compartment of the cars you see. Blasting everything with your grav gun will not help you at all.

One is near the bed, one is underneath a bathtub, and another one is on a plate, that you can see by looking up. Shoot bricks at the plate, so it falls down. The battery will fall down too.

Look in the car outside of the cabin.
In the hood, where the battery goes. ;-)

hehe, i was stuck there also for a short time, i found the outside battery , but never figured how to check inside the building - so i just used my gravity gun to punch the car over the wall
