The ATX20 is a standardized size used in a large number of Powersports Vehicles such as Touring Motorcycles, UTVs, ATVs and more. You may want to modify, or add extra accessories to these vehicles and need a more powerful battery with more Amp Hour Capacity. This is where the ATX20 HD model offers over TWICE the capacity of competitors Lithium Batteries of the same size! They also come with a Voltage Indicator test button on the battery so you can easily check its charge level. You can also track your battery condition and status via Bluetooth, by using the Lithium Battery Tracker.
