Electric Outboard Battery – 48V / 72V | On Demand

Baywatt designs and assembles custom marine-grade lithium battery packs for electric outboard motors. Each system is built on demand to match your exact requirements: voltage, connectors, casing size, and weight distribution.

Tailored Power for Baywatt Motors

• 48 V systems for 3 – 6 hp outboards
• 72 V systems for 10 – 15 hp outboards
• Available chemistries: NMC (Nickel-Manganese-Cobalt) and LiFePO₄ (LFP)
• HVIL & PMSM
  

Why We Recommend NMC for Outboards

For propulsion applications, NMC batteries provide the best ratio of power, weight, and efficiency. They deliver high discharge currents and maintain strong performance even in cold weather.

• Up to 40 % higher energy density than LFP
• Excellent power retention at low temperatures
• Lightweight design for improved planing and range
• Fast charge and discharge capability

Customization Options

• Connectors: Anderson, Amphenol, or custom marine HVIL
• Enclosures: IP67 aluminum housings, compact or elongated formats
  
• Parallel connection for extended range
• Optional Bluetooth monitoring or integrated display
