Greetings.
I have been using my AC 200 max together with B300 battery in my camper van for several years with good results.
I would like to expand my storage capacity.
Due to limited space, I cannot add additional B300.
I do have enough space to replace the existing B300 with a new B599K expansion battery.
If this is possible, what additional equipment or adjustments will I need.
Thanks
Jim
