To add some strain relief to the power cable I drilled 2 x 2.5mm holes into the battery holder and secured the power cable with a small zip tie.? A spot of liquid rubber on the exposed contacts top and bottom completes the job.
Double check your positive lead, I think I see some bare copper in your picture . Possibly a nick from stripping outer insulation, mine had both leads nicked.?
