What Rose Electronics does
Rose Electronics, doing business as Rose Batteries, is a privately held custom battery pack engineering and contract manufacturer founded in 1963 and headquartered in San Jose, California. The company designs and builds custom battery packs — incorporating Battery Management Systems (BMS), smart boards, fuel gauges, and supporting firmware — across chemistries including lithium-ion, lithium-polymer, sealed lead-acid, LiFePO4, NCA, NMC, and emerging chemistries such as lithium-sulfur and sodium-ion, using chipsets from Texas Instruments, Linear Technology, and Analog Devices. It supports an in-house battery lab for cell cycling, performance testing, and certification, and ships designs that meet UN 38.3, IEC 62133, UL, CSA, and MSHA standards.
The business operates a hybrid manufacturing model: US-based San Jose production handles high-complexity, low-volume and prototype work, while a Mexico-based maquiladora facility handles high-volume runs for customers building more than 10,000 batteries per year, all under ISO 9001:2015 (US) and ISO 13485 (Mexico) certifications. Go-to-market is engineering-led enterprise field sales targeting OEM customers across twelve application segments — IoT, drone and robotics, medical Class I/II, smart grid, military, UPS, intrinsically safe, oceanographic, Iridium satellite devices, LoRaWAN, rail, and emergency response — with named customers including Matternet, Zipline, Starship Technologies, Savioke, Nuro, and FEMA.
Revenue is generated through professional services for custom design (NRE on new product development, engineering samples, project management, certification support) and hardware sales of the resulting battery packs, supported by supply-chain management and direct-to-customer fulfillment. Pricing is quote-based with a free 30-minute engineering consultation offered as a top-of-funnel engagement tool; the company markets itself through technical blog content authored by its executives, proprietary battery calculators, and industry-conference presentations. Tropical Battery took an investment stake in the company around 2020 and places its CEO, Alexander Melville, as Executive Chairman of Rose Batteries, while day-to-day operations are run by CEO Chris Wunderlich.
