Rincell is set to introduce the RC50T, a tabless 21700 lithium-ion battery cell, at the DroneX exhibition on September 29, 2026. The company has already begun shipping the units to drone manufacturers.
Why it matters
The RC50T is engineered to support high-load mission phases such as take-off and payload lift, providing critical power density for specialized drone operations. Its NDAA compliance makes it a strategic choice for manufacturers needing verified domestic supply chain standards.
The RC50T features an energy density exceeding 265 Wh/kg and internal resistance between 3 and 4 milliohms. It offers a 5.2Ah nominal capacity and supports charging at rates up to 15A.
The players
Rincell
This Fremont-based company specializes in high-performance battery technology for the drone and robotics industries.
Parikh
He is one of the founders who established the battery technology firm in January 2023.
Nanda
He is a co-founder who helped launch the enterprise to develop specialized power solutions.
The details
This tabless cell utilizes silicon-graphite chemistry operating at a nominal 3.6V across a temperature range of -20 to 60 degrees Celsius. While volume production occurs in India, the company maintains a 6,500-square-foot pilot line in Fremont.
Timeline
The DroneX exhibition takes place in London from September 29-30, 2026.
Rincell was founded in January 2023.
A U.S. production facility is scheduled to come online in late 2027.
Roadmap
The push for high-density, NDAA-compliant power cells reflects a broader industry shift toward domestic supply chain security in the aerospace sector. Rincell is positioning itself to challenge established battery suppliers by prioritizing localized pilot manufacturing before scaling to full U.S. production.
Drone operators and fleet managers can expect improved lift capacity and longer mission times from aircraft utilizing the new 265 Wh/kg cell technology. The current pilot line operations in Fremont indicate that early availability will be focused on specialized industry partners rather than direct retail sales.
The takeaway
With a projected life cycle of over 500 charges, this battery cell is designed to withstand the rigorous demands of frequent industrial drone usage. Manufacturers should track the company's move toward domestic production in 2027 as a potential indicator of broader U.S. battery market expansion.
