hello I have a new ebikling 1200 watt motor and a 52 volt 20 amp unit pack power and it had full charge when they sent it.... so I test rode the bike and drew down the battery and then I charged it last night..ithe led 2 light was red and the fan was working for at least 4 hrs before I went to bed .... i. woke up and the green light was on so I went to install back on bike and controller and it turns the screen on for a sec then it dies . no power. so. I tested battery with tester on 2 v position and it reads 27. amp.s??????? so when I put it back on charger it doesn't charge it the light on thge charger stays green. indication of full charge. ahhhhhgggggghhh. . please help. I am sending good vibes to anyone who reads or helps. thanks for you time. ps I checked the connects it's good. ps. ok one more thing. when I test battery after putting on charger briefly it shows 57. so o. then I hook it up. when I hook up the. Sparking. Anti spark xt90 connector. it sparks. then I turn on and it the control screen fade out right away. so then I test battery and it shoe 27. is that the bus protection??????? I have all the wires hooked up correctly. maybe I'll do it again. unplug all wires and hook back up. ......update. so. I tried the steps over trying different things. so.
