I find the balance wires on the JBD 200A BMS to be extremely sensitive to any movement. As I was installing elements around the lifepo4 system I would get alarms from the BMS for over or under current conditions. This is a few weeks post install. After a lot of trouble-shooting jiggling one of...

SV Agres, can you describe the system you installed, are you using a lead acid battery with the alternator?

The balancing wires and connectors are all pre-made with the JBD BMS. There is no strain on the wires. I may need to redo the connector. Thanks

Hi all, can anyone tell me if there is any reason to prefer JBD app over the Overkill Solar app for monitoring and controlling the JBD BMS? thanks

Sunpower work well when they have air underneath for ventilation. (not too hot) I have two 100W panels I mounted on thin aluminum brackets on a bimini five years ago and they have been great. Saltwater application north of seattle.

Agreed, but both JBD and Overkill have an app. Is there a problem with either one?
