Changing out a shark case

[Rodney64]

Hi Guys

We have seen in rare cases users will have a short inside their mount which causes the BMS to shut down and may damage the case.

When this happens as you can see by the photo a certain amount of damage is done to the contacts before the BMS kicks in and shuts down the battery.


When damage is this bad then the case needs to be changed as well as the cradle.

Now this is a simple job for any one that can solder.

As you can see the case, cradle and all parts comes for the repair when you order the kit.

When removing the battery from the plastic case perhaps take a couple of photos. This will help jog your memory when reinstalling the battery into the new case.
Maybe this thread will be enough.

Its best to remove all the small screws and place them somewhere safe.

I always like using a magnetic bowl. I know where they are then.

Now remove all screws and place somewhere safe.

Now the battery will fall easily out of the case.

Now this is the part where care needs to be taken and we do not want to damage the battery any more or give ourselves a shock .

The negative and positive wires are both covered in silastic.

First cut one wire with a pair of pliers.

Now tap this with insulation tape to prevent a short.

Now its safe to cut the second wire

Photo below of the 2 wires that need to be cut.

Now all that's needed is to solder the red and blue wire to the new battery case. Below is a photo of both the old and new battery cases where it is soldered to.

Now apply some hot glue to the soldered joints.

Now its just a matter of moving the pack back into the new case.

The easiest way I find is to lift the middle of the pack in one hand and the lift the battery case (bottom) and lower it into the the new case it will just slide in, but you may need to hold the green paper if it catches on the side of the case. When its clear it just falls into place.
Now the charge point can be positioned into place. The charge point needs to be above the pack to reach its correct placement in the case.

Now we are just about finished. Its just a matter of replacing all the screws and making sure the battery case is positioned correctly and the the charge point is secure.
A misaligned cover will be quite evident with air gaps between the two.
