I noticed yesterday that the screw into my LiFEPo4 batteries had vibrated loose. They are mounted in my RV. How is the best way to prevent this from happening again? Can I use plain old loc tight on the threads that screw into the batteries
Valence batteries have loctite or something similar on their battery bolts. In an RV you should make it a regular habit to check all electrical connections. Vibration as well as expanding/contracting make them tend to come loose. I try to check mine about once a month.
