CM Batteries

What CM Batteries does

CM Batteries (legal entity: CM BATTERIES INC., incorporated in the USA) designs, engineers, and manufactures custom lithium-ion battery packs for demanding industrial and commercial applications. Founded in 2014 with operational headquarters in Dongguan, Guangdong, China, the company operates regional sales contacts in Mountain View, California and Douai, France, supporting a tri-region go-to-market targeting enterprise buyers across IoT, marine, robotics and drones, medical equipment, power and garden tools, industrial and commercial systems, and electric mobility. The product portfolio spans cell chemistries including LiPo, LiFePO4, NMC, Sodium Ion, and semi-solid-state; form factors from 14500/18650/21700 cylindrical cells to prismatic NCM and large-format 409.6V LiFePO4 systems; and feature-oriented variants including high-temperature packs (operating to 85°C with 500+ cycles), low-temperature packs (operation to -50°C with self-heating), and waterproof IP67-IP69 enclosures including IP68 at 100m depth. Supporting technology modules include a Smart Battery Management System with multi-protocol communication (TCP, UART, CAN, RS485, RS232, Bluetooth), immersion cooling, and 10C fast charge capability.

The company runs a sales-led B2B motion: customers submit inquiries, receive technical consultation, agree on custom specifications, prototype (delivered in approximately two weeks), and move into mass production with a stated MOQ of 200 units. Pricing is quote-based, anchored to voltage, capacity, cell chemistry, BMS requirements, certifications, and order volume. Revenue is generated through one-time hardware sales of custom packs and accessories (e.g., battery chargers), with no disclosed subscription or recurring software component. Customer engagement is supported by 24/7 technical consultation and dedicated project managers. Manufacturing is conducted in an ISO 9001:2015-certified facility with full IQC/IPQC/OQC traceability and certification support covering UL, CE, UN38.3, IEC62133, CB, RoHS, REACH, UL1642, UL2054, UL2580, PSE, KC, BIS, CCC, and MSDS.
