Especially designed for use with 48 volt golf carts and other 48V electric vehicles. Ideally mounted permanently to keep the batteries in optimum condition. The Battery Life Saver can be used on new good working batteries to extend battery life as well as old sulfated batteries. (The benefits of the BLS-48B have now been incorporated into the BLS-48N).

The BLS N series have a shutoff point around 90% State of Charge (SOC) and are designed for Electric Vehicles (EVs). The BLS-48N 48 volt battery desulfator is not intended for wind and solar type applications which regularly experience deeper discharge levels and require a BLS unit that will work full time. For these alternative energy applications you should use the BLS-48A.

FAQs About This Product

Ask a Question

  • I live off the grid and have 32 deep cycle batteries charged by solar panels, seasonal hydro and a generator. My system is 48V with Magnum inverters. Do you have anything like the XC100-P that would work to increase battery life?

    48 volt Series DiagramIt sounds like you want to prevent / remove the debilitating effects of sulfate in your batteries and would be best served with an on-board desulfator.

    The size of your battery bank may be best served by using 1 of 2 methods. A 36-48V High Powered Industrial Desulfator (BLS-36/48-Multi-F) made by Battery Life Saver or by breaking your system down into multiple sub-series and use the 12V or 24V units.

    Example a 48V system utilizing four 12 volt batteries could use four 12V Power Pulses or two 24V Power Pulses or one 48V unit.

  • What Is Sulfation?

    Sulfation is the buildup of lead sulfate (PbSo4) crystals on your battery plates.

    Contrast image of built up of sulfate crystals on a battery.All lead acid batteries will suffer from the effects of sulfation. It is the unwanted byproduct of the natural double sulfate chemical reaction that generates electricity within the battery. When a battery is in use, the active material on your battery’s plates, lead and lead dioxide, react with the electrolyte or sulfuric acid (H2SO4) to generate electricity. During this process a thin layer of non-crystalline solid lead sulfate is deposited on the plates.

    During charging, this sulfate deposit is supposed to be converted back to lead dioxide and sulfuric acid restoring the battery back to its pre-discharged state. However, the process is not perfect. Incomplete charging or prolonged time left in a discharged state will convert the amorphous (non-crystalline) lead sulfate into a hardened crystalized form diminishing the ability of the battery to reach full charge.

  • I own a 48v Club Car it gets light use on weekdays and heavier use (including towing a trailer) on the weekends. Do you recommend the N series or the A series for this application and why?
    To be honest, I think either one would be fine. On the weekends it sounds like you could be discharging greater than 50% SOC, yet during the week it sounds like you are probably staying above 70 or 80% SOC. There is not one scenario that seems to dominate. As long as the cart is being charged regularly, which it sounds like it is, I would lean towards the BLS-48N.
    Rate This Answer:

  • I have a BLS48-N and as it is hooked up I have a red light. Is this normal?
    Having the light turn on is a good sign it is hooked up correctly.
