High-Performance Custom Battery Packs Based on Samsung INR18650-25R Cells
20A High-Discharge Lithium-Ion Battery Pack Solutions for Power Tools, LEVs, and Industrial Equipment
Beyond Cells — We Deliver Reliable Power Systems
Samsung INR18650-25R is an industry-proven high-discharge lithium-ion cell.
We use it as a core building block to engineer safe, durable, and high-performance battery pack systems, integrating BMS protection, mechanical design, thermal management, and scalable manufacturing.
Trust Indicators
Power battery solutions delivered to OEMs and industrial customers worldwide
Battery packs designed to meet UN38.3 and relevant safety compliance requirements
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.
Low internal resistance and stable cycling behavior, combined with our optimized BMS strategy, significantly reduce premature aging, failures, and warranty costs.
The wide operating temperature range (-20°C to 75°C) allows battery packs to perform reliably in outdoor, vehicle-mounted, and industrial environments.
We apply strict voltage, capacity, and internal resistance matching before pack assembly — a prerequisite for long-term pack balance and safety.
