ePropulsion E-Series 48V Lithium Battery

The ePropulsion E-Series 48V Lithium Battery is purpose-built for marine electric propulsion, pairing high energy density with a long service life and tight integration with ePropulsion motors. It uses confirmed LiFePO₄ (lithium iron phosphate) chemistry, so it runs lighter and offers more usable capacity than traditional lead-acid banks — a clean, low-maintenance power source for electric boating. Choose the compact E60 (3072 Wh) for day trips and tenders, or the larger E163 (8346 Wh) when you want maximum range.

Key Features

• LiFePO₄ chemistry — high energy density, lighter weight, and strong cycle life versus lead-acid.
• Up to 3,000 cycles — long-lasting power that reduces replacement frequency.
• Smart motor integration — syncs data with ePropulsion systems for optimized performance and live monitoring.
• IP67 waterproof — sealed against dust and water immersion for demanding marine conditions.
• Tool-free, one-hand install — quick-connect design on E-Series packs.
• Maintenance-free — no fluid checks or venting, with an advanced BMS for safe, stable operation.

Specifications

Fully compatible with ePropulsion Spirit, Navy, and Pod Drive motors — ideal whether you’re cruising, fishing, or sailing.

Warranty

The E-Series is covered by ePropulsion’s 24-month limited warranty (from delivery to the first end customer) against defects in materials and workmanship under normal recreational use with proper installation and maintenance — free repair or replacement of defective parts. Commercial or professional use is not covered by the limited warranty (your local statutory warranty applies instead), and claims should be made within 6 months of discovering an issue.
