ASOL 18650-6S1P 22.2V 3500mAh Li-ion battery infographic — industrial drones and robotics

The ASOL18650-6S1P is a high-voltage cylindrical Li-ion battery pack built around a 6S1P architecture — six premium 18650 cylindrical cells in series, assembled in a protected pack and delivering 22.2V nominal voltage with 77.7Wh of energy. This elevated voltage platform is the industry standard for medium-to-large industrial drones, 20V/24V-class cordless power tools, and equipment that demands more torque and sustained output than lower-voltage packs can provide.

At the core of every pack is an integrated BMS that continuously monitors cell-level voltage, current, and temperature — providing multi-layer protection against overcharge, over-discharge, overcurrent, and short circuit. Safe operation from 0°C to +60°C.

Every unit ships from our quality-controlled production facility after passing full inspection: individual cell voltage matching (±10mV tolerance), complete charge/discharge cycle verification, and BMS functionality testing.
