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.

Frequently Asked Questions
Can I customize the connector and wire specifications?
Yes. We support JST, Molex, JST-PH, XT60, EC5, and other industry-standard connectors. Wire gauge, length, and polarity are all customizable to match your device interface. Just send us your pinout diagram or sample connector.
What is the minimum order quantity (MOQ)?
MOQ is confirmed after specification review. Sample evaluation may be available for selected cylindrical and lithium polymer battery projects, subject to specification review and product availability. Sample freight is paid by the customer.
Do you provide engineering support for device integration?
Absolutely. Our engineering team can supply pinout diagrams, charge/discharge characteristic curves, mechanical dimension drawings (2D/3D), and BMS communication protocol documentation.
What certifications are available?
Certification and test-document requirements depend on the selected cell, pack configuration and destination market. Please confirm requirements during project review.
