Use a solar panel to keep it charged.
I think I’d rather find the cause......solar panel isn’t fixing the actual issue.Quote:

All back to normal at the moment like it is 95% of the time. Thanks to Brian Elloy. The BM2 battery monitor will definitely help to solve the problem.Quote:

So I was in and out of the vehicle installing a coulomb counter to monitor the lithium batteries.
The dips are each time I unlocked the vehicle. No interior lights. Just the vehicle waking up and going back to sleep. Love this monitor. Can even get a connection in bed. How good is that!! Most closely watched battery on the planet.
I didn’t know what a coulomb counter was until I googled LiFePo4 battery gauge. The one I got looked identical to the one below but a third the cost from Hong Kong. With the mandatory Chinglish instruction sheet of course. Seem to be working so far....
