Battery repair

I need help with my Slingshot Racing sometimes. A few weeks ago everything seemed to be going fine and then the boat stopped. Dead.

Retrieval was the usual palaver - these things never die near the bank and there isn't much on the boat to grab hold of with a pole. The race carried on around me too. Thanks chaps.

Swapping the battery over for a spare cured the problem. Back at the bench it became obvious why. Some water had found its way under the battery cover and corroded the join between cell and wire. This had eventually parted company in the rough and tumble of the race.

Soldering the wire back in place after a quick clean with some emery paper was easy enough and the model is back on the water at full tilt. It doesn't look as pretty covered in insulating tape but I put that down for wear and tear. We can't all have a car like Louis Hamilton.
