Unrivaled Cranking Power for High-Compression V-Twins

When you are riding a large-displacement Harley-Davidson or a custom high-compression build, “standard” power isn’t enough. The Duraboost V-Twin DBLVT30L Lithium Ion Battery is engineered to meet the extreme demands of the biggest engines on the road. Utilizing premium Lithium Iron Phosphate (LiFePO4) chemistry, this battery delivers a massive 700 Cranking Amps (CA). This ensures that even the largest 114ci, 117ci, or modified Milwaukee-Eight and Twin Cam engines roar to life instantly, providing a consistent high-voltage discharge that traditional lead-acid batteries simply cannot sustain.

Extreme Weight Reduction & Performance Handling

One of the most transformative upgrades you can make to a heavy touring bike is reducing “top-heavy” weight. The DBLVT30L weighs only 6.83 lbs, making it nearly 70% lighter than the bulky 20+ lb AGM batteries it replaces. By removing over 14 lbs from the battery tray, you effectively lower the motorcycle’s center of gravity. This translates to better flickability in corners, easier low-speed maneuvering, and improved overall suspension response. With the Duraboost DBLVT30L, your dresser or bagger feels lighter and more agile than ever before.

Advanced Intelligence: Integrated Battery Management System (BMS)

Modern motorcycles are equipped with sophisticated electronics that require stable, clean power. The Duraboost DBLVT30L features an advanced integrated Battery Management System (BMS) that acts as a 24/7 guardian for your electrical system. This internal circuitry balances the individual lithium cells to ensure peak efficiency and prevents common causes of battery failure, such as over-charging and deep over-discharging. Whether you have a high-output stereo system or multiple GPS units, the BMS ensures your battery remains healthy and protected against electrical spikes.

Rugged Construction & Direct OEM Fitment

Durability is non-negotiable for V-Twin riders. The DBLVT30L is housed in a heavy-duty OEM-sized case (6.54″ L x 5.16″ W x 6.89″ H), designed specifically to drop into Harley-Davidson battery trays without the need for spacers or foam blocks. To ensure the best possible connection amidst high-vibration environments, it features flush-mount brass 2-position terminals. Brass offers superior conductivity over lead and resists the oxidation that often plagues traditional batteries, ensuring your bike gets every bit of the 700 amps available.

Maintenance-Free Reliability and Fast Charging

The Duraboost V-Twin Lithium series is designed for riders who would rather be on the road than in the garage. This battery features a remarkably low self-discharge rate, allowing it to hold a starting charge for up to one year of storage without a tender. The built-in LED voltage indicator provides an instant health check at the press of a button. When it is time to charge, lithium technology allows the DBLVT30L to reach a full charge significantly faster than lead-acid alternatives, so you spend less time tethered to the wall and more time in the saddle.

Note: To ensure longevity and validate the 2-year warranty, always utilize a lithium-compatible charger/maintainer.
