If one cell in a pack reaches that voltage before other cells reach a full charge it will cause the charger to shut off - prematurely denying the balance of the pack a full charge. Conversely when the weakest cell in a pack reaches its discharge cutoff voltage it will show as the discharge point and shut down the pack prematurely - thereby denying the user the balance of energy the other cells have stored. These battery equalizers prevent this from happening. This yields up to 30% more power and will extend the life of the battery pack. Benefits:Quick and easy installationKeeps your batteries voltage difference within 10mV!May increase the lifespan of your battery pack by 2-3 times by preventing the batteries from being overcharged or over discharged   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
