Having two 85AH AGM batteries is nice, I’d like to be able to keep them maintained and charged when the car is off.
For the longest time I don’t know why but I was against getting solar on my Toyota Prius I guess the thought of having additional hardware and load on my car, I guess I didn’t see the use for it.

While replacing the head gasket having various things for data to the stock main 120 battery and the engine unplugging everything my 2nd battery which ran all of my electronics was not able to be charged because I couldn’t turn the car.

This is the battery charger tender that I’ve used for many years up until now it worked great however the amp was just too low to charge my batteries

Now what you’re here for is the main attraction this is the Victron 15 amp battery charger and when I say it has yeah but I say it has completely changed the way I’ve thought about AGM batteries for one battery charges for 2 and the prius and using a VSR isolator.
