earthX ETX Lithium batteries, Lithium Iron Phosphate (LiFePO4), are designed to be a light-weight, maintenance free replacement of your standard lead-acid battery. These batteries will work with any vehicle charging system and “modern” lead-acid battery chargers, thanks to the exclusive built-in electronics (Battery Management System, BMS). No other motorsport lithium battery manufacturer offers a battery with built-in electronics to protect it from over-discharging, over-charging, plus keep the cell’s charge level balanced.
earthX batteries are an exceptional value given the fact they can last four times longer than a lead-acid battery, up to eight years. All of the motorsport batteries come with a full two year warranty (not prorated like others). If you are not 100% satisfied with the product, you may return it for a refund.
