IMR 18650 3.7V 1200mAh High-Drain Rechargeable Battery Cell – Reliable Power for IoT & Robotics | Pack of 1 (Best Performance)

IMR 18650 3.7V 1200mAh – Overview

The IMR 18650 3.7V 1200mAh rechargeable Li-ion battery cell from Shektronix is a high-drain cylindrical power cell optimized for embedded IoT sensor nodes, 2-wheel robotic chassis, motor driver circuits, portable electronics, and custom PCB designs. This is a flat-top unprotected IMR chemistry cell, widely used in applications that demand fast discharge rates, stable voltage curves, and efficient energy delivery.

Unlike protected 18650 variants that include an onboard BMS, the IMR 18650 3.7V 1200mAh format is designed to pair with external holders, charging modules, and regulated boost or buck power circuits, giving engineers full design flexibility for battery-powered IoT or robotics systems. The IMR chemistry ensures thermal stability, safer high-current discharge, and improved cycle reliability when compared to standard ICR cells.
