The JST connector by itself does not allow gratuitous change polarity, however, when preparing a
replacement battery care must be taken the red conductor is soldered to the positive (+) pole of the
battery (the polarity is depicted both on the battery and the pcb from the bottom side). Soldering the
leads requires some skill – you need to be quick and precise. Please be aware the plastic shield
around the pads could be easily molten when applying to much heat or solder. Additionally, these
batteries may suffer thermal damage when overheating the soldering pads too much. Have no fear
still, this is a simple operation that can be easily done at home or your airfield’s workshop.
Eventually, you can always ask a friend if you feel uncertain :)
