BS Battery BSLi‑08 Lithium LiFePO4 Battery – 300A CCA Ultra‑High‑Performance Lightweight Powersports & Watercraft Battery

OVERVIEW

The BS Battery BSLi‑08 delivers reliable starting power and stable voltage output for high‑compression engines and electric‑start systems. This compact 12.8V, 5Ah lithium iron phosphate battery replaces heavy, maintenance‑prone lead‑acid units across motorcycles, ATVs, and personal watercraft. Engineered with a leak‑proof, acid‑free chemistry, it provides consistent cranking authority without the weight penalty or toxic materials of traditional starter packs.

ENGINEERING & PERFORMANCE

Built on advanced lithium iron phosphate cells, this unit sustains steady voltage under load while delivering 300 cold‑cranking amps for rapid ignition response. The premium brass terminal posts are fitted with protective silicone gaskets to prevent corrosion, and the fully sealed enclosure operates safely at temperatures up to 446°F. Flexible multi‑position mounting accommodates installation angles up to 180°, while the integrated state‑of‑charge indicator allows instant visual monitoring without multimeter testing. The closed‑cell design handles extreme vibration and maintains low self‑discharge during long‑term storage, making it a direct replacement that meets standard OEM charging output requirements.
