Direct-Fit, No Workshop Rework

Designed specifically for LEAF ZE0/AZE0/ZE1. Mounting points align with the original case, so there’s no need for cutting or structural modification. Pre-terminated connectors help reduce wiring mistakes and speed up turnaround for busy workshops.

High Energy, Strong Power Delivery

A 50kWh-class battery capacity restores practical driving range and daily usability for Nissan LEAF vehicles. The pack combines automotive-grade cells with a durable structural design to ensure stable power delivery and consistent performance without requiring vehicle platform modifications.

Verified Quality, Simplified Installation

Each pack undergoes insulation testing and pack-level aging verification before shipment. Installation requires only a few key connections—PTC, high-voltage, and signal harness. Labeled harnesses and verified connectors help reduce wiring errors and support faster, repeatable deployments.

Vehicle-Ready CAN Communication

An optional CAN-bridge solution helps the vehicle communicate with the upgraded pack more smoothly, supporting stable SOC and range readouts while reducing common post-swap warning lights. It removes a major integration headache that often drives rework after LEAF upgrades.
