Our ETX Lithium batteries, Lithium Iron Phosphate (LiFePO4), are designed to be a light-weight, maintenance free replacement of your standard lead-acid battery. Our batteries will work with any vehicle charging system and “modern” lead-acid battery chargers, thanks to our 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.
Our batteries are an exceptional value given the fact they can last four times longer than a lead-acid battery, up to 8 years. All of our motorsport batteries come with a full 2 year warranty (not prorated like others). If you are not 100% satisfied with our product, you may return it for a refund (see our Shipping and Returns policy).
We engineer and assemble all our batteries in the U.S.A.
*Some small cc dirt bikes / ATVs (like a CRF250X) require a 5mm battery terminal screw. Our terminal adapter kit which includes a 5mm screw (sold separately) can be used for such installations.
Replaces Yuasa: YTX4L-BS, YB4L-B, YTZ5S, 6YB8L-B
Our batteries are in stock and will ship within 24hours (unless noted otherwise at check-out)!
