In addition to all of my other troubles with connectors, the heatshrink that wraps my MagicShine battery is starting to split.

For now, I've temporarily taped over the ends of the battery with self amalgamating tape, but this certainly not a good enough fix.

I thought about wrapping it in rubber (from an old inner tube), but doing this will not allow it to fit in the little velcro bag.

I could try to find more heat shrink (in that large a size it will not be simple).

Anybody have any suggestions or experience?
