• Battery packs designed to meet UN38.3 and relevant safety compliance requirements

Why Build Battery Packs Based on Samsung INR18650-25R?

Eliminate Power Anxiety at Peak Load

The 25R cell supports 20A continuous discharge, enabling battery packs that maintain torque and acceleration under heavy load conditions — no power drop at startup or under stress.

Reduce Total Cost of Ownership

Low internal resistance and stable cycling behavior, combined with our optimized BMS strategy, significantly reduce premature aging, failures, and warranty costs.

Operate Reliably in Harsh Environments

The wide operating temperature range (-20°C to 75°C) allows battery packs to perform reliably in outdoor, vehicle-mounted, and industrial environments.

Build on Matched, Consistent Cell Foundations

We apply strict voltage, capacity, and internal resistance matching before pack assembly — a prerequisite for long-term pack balance and safety.
