What They Do

Big Ass Battery develops and manufactures portable and container-based battery energy systems that serve as clean alternatives to diesel generators, with a strong focus on mobile and modular applications for construction sites, peak shaving, EV charging support, and solar energy storage (source: linkedin.com, bigassbattery.com, ewmagazine.nl). The company builds systems from battery cells up to complete 10ft battery containers and integrates advanced software and energy management systems that control charging, discharging, peak shaving, and on-site energy routing (source: linkedin.com, ewmagazine.nl). According to TNO, the company focuses on emission-free construction sites with optional fast chargers, peak shaving between grid and end user, and storage at solar parks for energy trading at variable prices (source: fasttrack.tno.nl). Big Ass Battery purchases LFP cells and assembles battery packs in-house, which is a distinctive factor in their technology approach (source: fasttrack.tno.nl). Their systems also support EV charging stations, electrification of construction sites, grid reinforcement for commercial buildings with limited connection capacity, and off-grid applications at festivals and heavy EV charging locations (source: linkedin.com, siliconcanals.com).

Projects & Experience

Big Ass Battery has played a key role in the electrification of the construction sector, including a major dike reinforcement project where electric machinery was supported by their battery containers that also served as fast charging and power supply solutions (source: ewmagazine.nl). Additionally, their systems were deployed at the "Castle of Sinterklaas" in Helmond to handle extra power demand during grid congestion (source: bigassbattery.com). Prior to bankruptcy, the company served construction sites, large events, commercial buildings, the agricultural sector, and solar parks, with some battery containers remaining in use post-insolvency while the trustee attempted to continue service (source: siliconcanals.com, deondernemer.nl). The systems can reach capacities up to 800 kWh and are specifically designed for construction and peak management applications (source: fasttrack.tno.nl).

Recent Developments

In September 2025, Big Ass Battery and its related entities were declared bankrupt by the Oost-Brabant court, with the cause attributed to intense Chinese price competition and a defaulting customer (source: solarmagazine.nl, deondernemer.nl, siliconcanals.com). In October 2025, a restart followed under a new structure with founders Guido de Jong and Roel Vossen continuing core activities, focusing on providing storage solutions from selected brands rather than producing their own batteries (source: engineersonline.nl). This restart included a move to a new location in Eindhoven and a strengthened emphasis on service, support, and partnerships within the Brainport region (source: engineersonline.nl). Early 2025 still saw job postings for technical roles such as Test & Commissioning Technician, indicating an active engineering and system integration organization (source: linkedin.com).

Working at Big Ass Battery

Big Ass Battery offers roles in engineering, production, service, commissioning, and operations. Current vacancies include Service Engineer – Battery Systems and Test & Commissioning Technician, with the company building and testing its own battery packs in Helmond (source: linkedin.com, linkedin.com, ewmagazine.nl). In November 2023, the company moved to a new 15,000 m² production facility with a total site area of 41,775 m², indicating a production- and logistics-intensive work environment (source: linkedin.com). The primary employment locations are Helmond and, after the restart, also Eindhoven, with a company culture emphasizing rapid growth, high technical ambition, and a scale-up mentality (source: linkedin.com, bigassbattery.com).
