This pack contains one IMR 18650 3.7V 1200mAh 4.44Wh flat-top rechargeable cell, one durable 18650 battery holder, and one USB Type-C TP4056 1A charging module featuring smart auto cut-off and dual LED charge status indicators. This combo is built for users who want a simple plug-and-charge battery solution without compatibility concerns. The IMR chemistry cell falls under the high-drain category, which means it can deliver higher current when required while maintaining better thermal stability than standard low-drain cells.
