High-Performance Lithium Power for the Spirit 2 Platform

The ePropulsion Spirit Battery Ultra is a premium 48V lithium battery engineered to deliver maximum performance, portability, and runtime for the Spirit 2 electric outboard system. Designed with advanced Nickel Manganese Cobalt (NMC) cell technology, it offers exceptional energy density in a compact, removable package—ideal for tenders, dinghies, daysailers, and lightweight cruising applications.

Extended Range, Compact Form

With a rated capacity of 1,539 Wh (32 Ah) and a nominal voltage of 48.1V, the Spirit Battery Ultra provides substantial runtime while maintaining manageable weight and size. Its optimized energy density allows boaters to travel farther without adding unnecessary bulk, making it easy to transport, swap, or store between outings.

Smart, User-Focused Design

Installation and removal are fast and tool-free thanks to the integrated quick-connect design. A built-in state-of-charge indicator allows you to monitor battery levels at a glance, giving you confidence before and during every trip. The battery also includes a USB-C output, enabling you to charge phones, tablets, or onboard electronics directly from your propulsion battery—adding versatility beyond pure propulsion.

Marine-Ready Reliability

Built specifically for the marine environment, the Spirit Battery Ultra incorporates an advanced Battery Management System (BMS) to protect against over-charge, over-discharge, overheating, and short circuits. The durable housing and integrated safety architecture ensure dependable performance in demanding on-water conditions.

Seamless Integration with Spirit 2

Designed exclusively for compatibility with the Spirit 2 outboard, this battery delivers the precise voltage and performance profile required for smooth, efficient electric propulsion. Whether you’re upgrading your existing setup or adding a spare battery for extended range, the Spirit Battery Ultra provides dependable, high-efficiency power when you need it most.
