BS Battery BSLi‑04 / BSLi‑06 Lithium LiFePO4 Battery – 280A CCA Ultra‑Lightweight High‑Performance Powersports Battery

OVERVIEW

BS Battery replaces lead-acid sources with a precision 12.8V LiFePO4 cell that maintains stable voltage output and reliable starting current. Constructed with sealed cathode plates, brass terminals protected by silicone seals, and a visible state-of-charge monitor, this maintenance-free unit drastically cuts weight while preventing acid leaks and terminal degradation. An adaptable mounting bracket secures the battery at angles up to 180°, supporting flexible installation on high-capacity motorcycle applications designed for aggressive riding.

ENGINEERING & PERFORMANCE

This LiFePO4 battery delivers stable 280A CCA and rapid voltage recovery for immediate engine turnover, while heat-resistant materials support safe operation up to 446°F. The sealed design resists sulfation, corrosion, and fluid spillage across orientations, enabling direct replacement with OEM systems due to a 4A maximum compatible charge rating.

KEY FEATURES

• LiFePO4 chemistry with 280A CCA and 12.8V nominal voltage for reliable starting
• 2.1 lb weight delivering up to 70% reduction versus lead-acid equivalents
• Integrated state-of-charge indicator and over 2,000 recharge cycles
• Multi-position mounting capability allowing secure installation up to 180° orientation
• Sealed construction with brass terminals and silicone seals prevents leaks and corrosion
• Heat-resistant architecture operating up to 446°F with max 4A charge rate

WHY RIDERS CHOOSE THIS

Riders install this battery to cure inconsistent voltage drops and sluggish cranking common with aging lead-acid units, benefiting from steady 280A delivery even under heavy load. Sealed LiFePO4 cells and silicone-wrapped brass terminals shield against corrosion and leakage in wet or dusty environments, ensuring clean power distribution throughout the machine's lifecycle. By reducing mass without sacrificing strength, the pack improves handling dynamics and suspension response on demanding dual-sport motorcycles, adventure platforms, and torque-heavy utility vehicles.
