Remove all of the top screws
from the battery cover

on the battery cover
Lift the battery cover or
remove it completely
for easier access.

Notice the layout of protection foam
Insert the battery into the casing. The cables must face towards the back. All relevant
cables have been marked with numbers. Connect them carefully. Cables without a
number don’t need to be connected to anything.
We recommend using small amount of isolation tape to wrap all of the connectors.
This is to ensure that they don’t disconnect or short circuit during use.

Place the protection foam between the battery and loose cables.
Now, place the controller and cables on the protection foam

Place the sponge on top of everything
and close the battery cover
Secure the cover with
front main bolt.

If the EV4 does not start please check if all cables were properly connected. Wires that haven’t a number
attached to them don’t need to be connected to anything. If the vehicle still does not start please refer to
the manual to check the fuse or contact the manufacturer for advice.
Last step is to reinsert all of the
top screws and enjoy the ride.
Reinsert all of the side screws.
