I am having some trouble with a battery pack from Calibike. I just purchased a 48V 15ah pack. This battery has two connectors, one charge port and a pack power, and a switch on it. I assume that the switch goes to the PCM. The pack shows 54.2V fully charged with the switch on and 49V with the switch off. The problem I am having is the controller does not want to turn on most of the time with this pack. When I use my Lipo 12S pack (no PCM), the controller works every time. I have tested this with two other bikes with the same result. I would like to know what troubleshooting steps I might take to get this pack operating consistently.
