AA Portable Power Corporation

What AA Portable Power Corporation does

AA Portable Power Corporation (dba BatterySpace.com) is a privately held, Richmond, California–based manufacturer and distributor of rechargeable batteries, chargers, and battery-management electronics, founded in 2000 by former BYD USA team members. Its product portfolio spans single cells across seven chemistries (Nimh, Nicd, Lead Acid, Li-ion, Polymer, LiFePO4, Lithium Titanate, and primary cells), custom battery packs with integrated PCM/PCB/BMS protection for 1–24 cell configurations, multi-chemistry chargers, and a full suite of UN38.3 safety testing equipment. Since 2014 the company has operated an in-house UN38.3 Safety Testing Lab in Richmond and sells both the testing service (covering T1–T8 procedures with 1–8 week lead times) and the underlying lab equipment to other battery manufacturers. The firm also offers private labeling at a 10,000-unit minimum and has Shenzhen, China production lines for PCB and battery pack assembly.

The business model combines self-serve e-commerce (BatterySpace.com, with a localized batteryspace.jp storefront) for SMB and individual buyers with direct sales support (phone/email) for custom pack design, government and school purchase orders, and bulk private-label engagements. A Tokyo office handles the Japanese market directly. The company emphasizes credit, buying power, and reliable sourcing derived from its joint-venture relationships with multiple battery and charger manufacturers, and leverages 20+ years of industry experience and 10+ years of engineering tenure as a sales lever for custom design work. Operations span North America (USA, Canada), Europe, Australia, New Zealand, India, and Japan, with no institutional investors, parent entity, or public filings disclosed.

Revenue mechanics are anchored in hardware sales of cells, packs, and chargers, augmented by professional-services revenue from UN38.3 testing and equipment sales, and episodic high-volume private-label contracts. No headcount beyond the 11–50 band, no management roster, no customer logos, no patents, and no funding history are disclosed, making the firm analytically opaque on financial scale.
