I have a 60 volt battery pack. when i charge the battery and green light says charged , i disconnect charger and try to test voltage and get nothing at battery. Once i install battery and turn on bike i have voltage at controller. Im confused as ive never run into this before. I must admit im lost as to why when battery is on bench no voltage so asking if after hooking up to bike and turning on switch that there is a internal relay in battery??. Thanks for reading this .
