BS Battery BSLi‑01 Lithium LiFePO4 Battery – 140A CCA Ultra‑Lightweight High‑Performance Powersports Battery

OVERVIEW

The BS Battery BSLi‑01 delivers reliable starting power and stable voltage output for high-performance off-road and street machines using advanced lithium iron phosphate chemistry.
This sealed, maintenance-free 12.8V unit replaces heavy traditional batteries while providing precise electrical distribution across dirt bikes and sport platforms.
Constructed with durable internal architecture and brass terminals, it eliminates acid risks and reduces total system weight to just 0.9 lbs for improved handling dynamics.

ENGINEERING & PERFORMANCE

Engineered with LiFePO4 cell structure, the BSLi‑01 maintains consistent peak voltage during aggressive acceleration and hard-launch scenarios without voltage sag.
The reinforced design withstands continuous vibration and thermal loads up to 446°F, ensuring dependable operation across rough terrain and extreme temperature swings.
Sealed construction prevents fluid loss and corrosion, allowing for flexible multi-position mounting within tight underbody chassis layouts.
Zero-self-discharge characteristics retain energy charge during extended storage periods, supporting immediate throttle-on responsiveness whenever needed.
