  • can I hook this up to 6 - 8 v batteries in golf cart - if so what is proper installation procedure thanks Tom

    You would be better served using the BLS-36N or BLS-48N for your golf cart.

    Theoretically and very cumbersomely, (if you will allow me to create such a word) you could use the BLS-12N on sets of two 6V batteries and then change to the next set and then the final set. You could keep this rotation up, but that would be silly.

  • Hello. What is the difference between BLS-48N, A, B ?Do these really work? How would one know? Asking because people in the battery business say they're not worth the time adding them to a PV system (48V solar/battery: 24 large 2V sealed cells).

    We hear that a lot from battery sales men, even the ones we like. Yet, when we asked them if they tried one, they often say no. when we present some improved metrics they find a way to marginalize them.

    I have not seen any harm come to batteries with on board desulfators. I have seen noticeable improvements with them attached. That is a small price to pay to extend the life of your batteries.

    The BLS-48 N and B are the same; they were merged into one unit. These units are designed to excel on electric vehicles and similar applications. The BLS-48A is better suited for renewable energy systems that frequently have deep discharges.
