The 15-Minute Battery: Inside Base Power's Austin Factory
Key points
Key takeaways from a Sourcery with Molly O'Shea factory tour with Base Power co-founder and COO Justin Lopas (August ️2026):
Fresh off the line. The Austin production floor is barely six months old: the company moved in during September–October ️2025, got the assembly line built from February–March ️2026 onward,and now runs it with around 100 people,with a second shift being added.
A battery that snaps together. BaseCore packs 40 kWh of storage and a 20 kW inverter — roughly three times a traditional home battery — in modules that stack and plug in like an EV. An electrician installs the control box in one–three hours; two delivery staff then plug the battery together in about 15–30 minutes,with no wiring or conduit work.
Whole-home backup, seamless. The system backs up every circuit in the house, not selected ones — and when the grid drops,the battery takes over so fast that homeowners often don't notice an outage at all. A generator port lets them top the battery up during multi-day outages.
Built for 15-year, no-touch reliability. R&D stress-tests units in thermal chambers at up to 85°C and 85% humidity — harsher than any real climate — because the model only works if a battery can be installed in hours and then left untouched for a decade and a half.
Vertical integration as the manufacturing thesis. Base designs its own cells-to-system hardware, writes the manufacturing-execution software that controls its lines, and mixes robotic glue-and-placement cells and friction-stir welders with manual stations where dexterity beats automation. Building in-house cuts cost and lead time,and lets engineers drive over from HQ to change a line the same day.
Ramping hard. Base is installing over 100 systems a day,with 100+ field staff; it targets around 4,000 units a week by the end of the year — roughly one every few minutes —and is adding a second factory by the Austin airport. It also plans to bring manufacturing back to the US.
"Everything is a factory." Lopas applies lean discipline across installation, logistics and delivery,not just the production line,with Base running its own installsand deliveries to keep cycle times short.
