The smallest in Antigravity Batteries' lineup, this battery measures 4.25" x 1.25" x 3.75" (to the top of the terminals) and boasts an ultra-compact size with extreme power. Ideal for applications requiring significant weight loss and minimal size, it's often used in performance applications due to its compactness and lightweight. Capable of starting inline 4-cylinder motors up to 600cc for race use or 250cc for daily street use on scooters, this battery is also a favorite among custom builders looking to tuck it out of sight. Featuring adhesive-backed foam for easy installation, the battery is an ultra-lightweight Lithium Nano-Phosphate Motorsport option that can hold a charge up to a year without parasitic drains like alarms, ECUs, iPods, GPS units, or heated grips. Built in the USA with large brass terminal design and backed by a 3-year warranty, it's waterproof and suitable for everyday use on bikes up to 250cc, race use on Enduro and MX electric start bikes up to 450cc, and track day use on inline 4-cylinder sport bikes. It also works well in custom builds like cafe racers or small bore customs up to 350cc, though older classic bikes may require updating charging systems for modern voltage regulators. The battery boasts 120 cranking amps and 6 amp hours (PB Eq) with dimensions of 4.25" x 1.25" x 3.75" and a weight of 16oz (or 448g in metric units).
