Duraboost V-Twin DBLVT20L Lithium Ion Battery For Harley

Premium Cranking Power for Your High-Performance Harley

Elevate your riding experience with the Duraboost V-Twin DBLVT20L Lithium Ion Battery, specifically engineered to meet the rigorous demands of American V-Twin engines. Standard lead-acid batteries often struggle with the massive torque required to start a Harley-Davidson, but the DBLVT20L utilizes advanced Lithium Iron Phosphate (LiFePO4) technology to provide a relentless 500 Cranking Amps (CA). This ensures your motorcycle roars to life instantly, providing consistent, high-voltage output even in the most demanding conditions.

Extreme Weight Savings & Improved Agility

One of the most effective ways to improve your motorcycle’s handling is by reducing “sprung weight.” The Duraboost DBLVT20L weighs a mere 5.29 lbs, replacing traditional lead-acid batteries that can weigh up to 15 lbs or more. By shedding nearly 10 lbs from your battery tray, you lower the bike’s center of gravity, resulting in sharper handling, improved braking performance, and better flickability through tight corners. It is the easiest performance upgrade you can install in minutes.

Advanced Integrated Battery Management System (BMS)

Safety and longevity are at the core of the Duraboost design. The DBLVT20L features a sophisticated integrated Battery Management System (BMS). This internal “brain” constantly monitors the health of the lithium cells, protecting against over-charging, deep discharge, and thermal instability. Whether you are running a high-output security system or customized LED lighting, the BMS ensures your battery remains protected from parasitic drain and electrical spikes, extending the lifespan far beyond traditional batteries.

Rugged Durability & Seamless OEM Fitment

Riders demand gear that can withstand the heavy vibration of a V-Twin engine. The DBLVT20L is built into a heavy-duty OEM-sized case (6.89″ L x 3.43″ W x 6.10″ H), ensuring a perfect drop-in fit for Harley-Davidson models without the need for spacers or foam padding. To ensure maximum conductivity, this battery is equipped with heavy-duty brass terminals. Unlike lead terminals that can oxidize or strip, these brass connections provide a rock-solid, corrosion-resistant interface for your bike’s primary power leads.

Maintenance-Free Reliability for the Modern Rider

The Duraboost DBLVT20L is designed for the rider who wants to spend more time on the road and less time on a trickle charger. Lithium technology offers an exceptionally low self-discharge rate, meaning it can hold its charge for up to a year in storage without a load. The built-in LED voltage indicator allows for a quick health check at the push of a button. Additionally, lithium cells charge up to 90% faster than lead-acid alternatives, getting you out of the garage and back onto the pavement in record time.

Note: To preserve the 2-year warranty and ensure optimal cell balancing, always use a lithium-specific smart charger/maintainer.
