I recently built a battery with a JBD BMS. It is up and running. I added another newly built battery ( 16 cells ). The same JBD BMS AP21S 002. I found it on my phone app and then I lost it. When I open the app only one battery shows up. Sometimes the blue light flashes but I don't get the solid blue. ( On the new battery BMS ) The two batteries are hooked up in parallel. They are both hooked up to my victron smart shunt. The new battery is not charging or discharging. I am thinking it is something to do with Bluetooth, but I really don't know. Any suggestions or ideas will be greatly appreciated .
