Hi all, first time poster and have tried to research before posting. I have a JK BMS (Model K-B2A24S0P). I have it wired to my 16s 48v battery. Battery is made up of 16 - 3.2v 200ah prismatic cells. I have tested it for the correct voltage on the individual pins and have verified voltage on the battery pack. Once I connect the BMS, I do not get any voltage from the battery pack. No red light on the BMS. I have make a 5v battery from AA batteries with a leads, and a 9v battery with leads to short across the B- and P- cables of the BMS still no light. Is there a secret to these things? Looking for any suggestions that others might have come across. Thanks in advance.
