Replace an old battery with a new one

I haven't seen any battery with this connector available, so you will have to do a bit of soldering
Mind the polarity of battery connector. Note that the red wire should be on outer side of the puck, while the black one in the inner side.
Messing with polarity may force you to replace this puck entierly and the new one costs 48$
After you connect a new battery, your puck will flash a few times, this is expected
You will have to recalibrate the sensor puck after full reassembly. In fact, the application on your phone will remind you of this.
