What Stafl Systems does
Stafl Systems LLC is a privately held engineering and manufacturing company founded in 2010 by Erik Stafl and headquartered in South San Francisco, California. The company designs and produces integrated lithium-ion battery systems, with a product family that spans Battery Management System master and monitor units (BMS1000M, BMS1101S, BMS1102S), custom and catalog battery packs ranging from 12V to 1000V (including the BAT1400 1.1 kWh aviation pack and BAT1411 11.6 kWh / 400V automotive pack), a programmable 60-pin Vehicle Control Unit (VCU1200), a GPS/cellular Telematics Control Unit (TCU1500), and a cloud fleet management sub-brand called Stafl Fleet. Core technology centers on CAN 2.0B-based modular BMS architecture scaling from 12 to 256 series cells and up to 850V, with proprietary algorithms including Safe Operating Envelope (SOE), Fault Vectoring, and patented Vectored Isolation Fault Monitoring, plus active cell balancing and sub-3 mV cell voltage measurement accuracy.
Stafl sells through a hybrid model: direct website e-commerce for standard catalog items (TCU1500 at $100, VCU1200 at $500, BMS1102S at $400, custom packs starting at $750) and direct enterprise engagement for custom-engineered battery packs, vehicle control, and powertrain integration projects. Customer end-markets span industrial, marine, mining, aerospace, automotive, and robotics, with named engagements including Genovation Cars (world's fastest street-legal electric car using Stafl VCU and 800V systems), an unnamed major OEM's Class 8 electric semi-truck program (300 kWh, 800V, 1 MW traction), an unnamed major mining company's 20-22 hour/day underground electric vehicle, solar-powered electric aircraft programs, and an unnamed consumer product company that launched a battery-powered product in 2021. The company has exclusive cell supply arrangements (notably AER CELL Technologies for the 4 Ah aviation pouch cell) and in-house rapid-prototyping, SMT, and battery pack manufacturing at its South San Francisco facility. No external institutional equity funding rounds are disclosed; the firm has historically operated as founder-controlled, with a single WindSail Capital Group relationship recorded in June 2024.
