iGSport IGS-20E Bicycle GPS Speedometer Internal lithium battery replacement.

Here's our 3rd and possibly the last bicycle GPS internal battery replacement how-to video.
This time, we are changing the battery of the iGPSport IGS-20E GPS speedometer unit.
Soldering is required.
Apologies for the poor video resolution as this was repurposed from our 9:16 youtube short clip. We thought to put as our regular video as that yields better search-ability and longevity.
