Review on PowerMax PM4 45A Converter Battery by Russell Wong

Revainrating 5 out of 5

The best battery investment you can make for your RV

Great investment - PowerMax 55 MBA and upgrade to this PM4 75A MBA holds four 6 volt deep cell batteries at ideal voltage . After 40 years. Working in the field of electronics, I sincerely believe that PowerMax not only excels in design and workmanship, but offers it all at the lowest price $$$$

Pros
  • Lots of positive vibes
Cons
  • Really don't like it, everything is fine
