Our power bank has been completed. Took out 4 old lead acid batteries and replaced them with new AGM batteries. Nothing is easy on a boat and nor was this job. Back and forth to hardware store 3 different times for items needed to finish job! You would think that the terminals and posts would be universal sizes, yup LMAO not so much. That being said we should be well equipped for energy now. Next on the punch card will be more maintenance issues and placing a galvanic isolator onboard.
