What emus does

EMUS is a privately held Lithuanian manufacturer (Vilnius, HQ) that designs and sells modular, scalable Battery Management Systems (BMS) for lithium-ion battery packs. The portfolio is built around two platforms: the BMS Mini series (Mini 1 and Mini 3), an integrated, all-in-one low-voltage BMS for 3–16 series cells with built-in contactors, MOSFETs, pre-charge, Bluetooth and CAN interfaces; and the G1 platform, a distributed/centralized/clustered architecture that scales from a single Control Unit up to 8,128 cells via CAN Cell Group Modules (CCGM), supported by a family of Cell Modules (1.4A–6.125A balancing variants), dual-range and high-accuracy CAN current sensors, temperature boards, CAN filters/isolators and cabling accessories. Core technology centers on advanced State-of-Charge (SOC) and State-of-Health (SOH) estimation (Kalman filter and Coulomb counting), native CAN 2.0A/B and J1939 protocol support, and pre-validated integration with 20+ third-party chargers/inverters (Victron, Delta-Q, SMA, Deye, GoodWe, Growatt, Elcon, Eltek, Ingeteam, Brusa, Shinry, Sermatec, PYLON, Isabellenhütte, among others).

EMUS monetizes primarily through hardware sales — Control Units, Cell Modules, CCGMs, current sensors and accessories — sold globally via its direct e-commerce storefront, with quote-based pricing and a two-year warranty. The company augments hardware revenue with a Series Production Validation service for customers transitioning into volume manufacturing. Go-to-market is direct (phone/email sales, regional phone support) plus a wholly-owned US subsidiary (EMUS USA Inc., Greenville, SC) serving North America. Demand generation leans on industry events (The Battery Show North America in Detroit and The Battery Show Europe in Stuttgart), a Tech Blog, downloadable firmware/protocol documentation and technical sales engineering. End-use segments include light electric vehicles (e-bikes, scooters, motorcycles, delivery vehicles), robotics and AGVs/UGVs, industrial equipment (forklifts, warehousing, cleaning machines), stationary and portable energy storage, marine vessels, and agricultural/residential battery systems.

EMUS is a small, owner-controlled private company (11–50 employees, no disclosed external funding, no parent or institutional investor identified) with a wholly-owned US sales entity. Geographic footprint is stated as global, with operating geographies explicitly covering Lithuania (HQ/R&D) and the USA (regional sales). No awards, certifications, patents, M&A, leadership changes or restructuring events are disclosed in the source materials.

Core offering

EMUS develops and manufactures lithium battery management systems (BMS) and related hardware, including control units, cell modules, CAN cell group modules, current sensors, and accessories. The BMS portfolio supports distributed, centralized, and clustered architectures across low and high voltage applications, serving e-mobility, robotics, energy storage, industrial, marine, and agricultural segments.

Product overview

EMUS produces modular, scalable Battery Management Systems (BMS) for lithium batteries across distributed, centralized, and clustered architectures. The product portfolio centers on two main platforms: the compact, all-in-one BMS Mini series (Mini 1 and Mini 3) for low-voltage applications up to 16 cells, and the scalable G1 platform consisting of Control Units, Cell Modules, CAN Cell Group Modules, Current Sensors, and accessories. The G1 Control Unit serves as the main intelligence, supporting up to 8,128 cells when paired with CAN Cell Group Modules. The system offers comprehensive connectivity including CAN, USB, RS-232, and Bluetooth interfaces, with native integration of 20+ charger and inverter brands (Victron, Delta-Q, Deye, SMA, Elcon, and others). Advanced SOC/SOH algorithms provide predictive battery analytics, while modular accessories include current sensors, temperature monitoring, CAN filters, and various cables/connectors for system assembly.
