    Deep Discharge

    Okay, so I seem to have made some sort of weird discovery when it comes to my Focus resisting a charge after riding it deep "into the red." Symptoms would be that the charger would flash green for a few seconds, click once, flash a couple more times, click again and then fail. The last few...

    Answered Focus Jam2 battery charging problem
