Overview

ADVANCED LITHIUM MARINE BATTERY SYSTEMS

Litmus Marine specializes in advanced marine battery systems, supplying highly reliable, waterproof (IP67), and intelligent lithium-ion battery banks configured for premium electric outboards. We offer full CAN bus integration, customized multi-battery capacity banking, and smart Battery Management Systems (BMS) to optimize safety, thermal health, and real-time GPS range counting.

Our battery range features premium automotive-grade BMW i module tech, ultra-safe LFP cell-to-pack high-density modules, and robust CNC-machined aluminium configurations. We support everything from ultralight portable click-and-play batteries for kayak outboards up to high-voltage, heavy-duty commercial boat battery systems from CATL, EVE, and BMW.

Our Lithium Battery Systems feature:

Smart BMS with protection against overcharging, short circuit, and submersion
IP67 waterproof and shock-resistant marine configurations
Extreme volumetric energy density using BMW i & LFP cell-to-pack tech
Abundant cycle life (up to 3000+ charges) with minimal annual capacity loss
