With the rapid growth of electric two- and three-wheelers worldwide, reliable EV charging and discharging connectors have become essential for safe and efficient power transfer. The Chogori Large 2+1+5 series has been a proven industry-standard battery connector for nearly a decade. As e-mobility evolves toward higher voltage, higher current, and longer range, the demand for high-performance connectors continues to rise. At the same time, batteries—being high-value assets—require enhanced protection, as water ingress can lead to performance issues and costly maintenance. This creates a growing need for connectors that provide waterproof protection even in an unmated condition.

In response, we developed the next-generation Large Pro 2+1+5 — a high-performance EV connector for electric two- and three-wheelers.

The Large Pro 2+1+5 is a high-performance EV charging and discharging connector designed specifically for electric two- and three-wheelers. It supports up to 300V / 50A, featuring high reliability, user-friendly operation, and full compatibility with the Large 2+1+5 series.
Engineered for e-mobility and battery systems, this connector enables safe, stable, and efficient power connection even in harsh environments — helping customers achieve reliable charging under complex conditions.
