24 to 48 volt upgrade
I've had four Rolls S530 6 volt batteries in series for about 2.5 years, and am planning to upgrade to a 48 volt system. Some seem to think I can add four new S530s to the string without impacting their health or lifespan, while others think it's a mistake, meaning I'd need to purchase (gulp) eight new batteries. Thoughts? Thanks.
