Bren-Tronics Defense LLC

Bren-Tronics Defense LLC, doing business as Bren-Tronics Inc., manufactures storage batteries, battery chargers, battery adapters, cable assemblies, and related power management components for the Department of Defense as a prime contractor (97% of recent awards) and occasional subcontractor on major defense primes. The company is a small business subsidiary of Enersys Advanced Systems Inc., headquartered in Commack, New York, with over 49 years of operational history in advanced battery technologies and portable power solutions. Bren-Tronics competes full-and-open without set-aside designation on nearly all of its prime work, though certain awards carry Total Small Business set-asides.

Bren-Tronics' customer footprint concentrates overwhelmingly on the Defense Logistics Agency. DLA Land and Maritime accounts for 1,008 awards (42% of the prime portfolio) valued at $382 million combined potential value, while DLA Aviation holds 481 awards worth $51.1 million. Together, these two DLA components represent roughly 67% of all awards. The Army Materiel Command Communications Electronics Command (CECOM) is the third-largest customer with 58 awards valued at $103.9 million. This concentration reflects Bren-Tronics' role as a routine supplier of batteries, adapters, and power components to military logistics operations rather than a prime systems integrator or platform contractor.

Bren-Tronics holds multiple active indefinite delivery contracts anchoring its business. A $13.9 million multiple-award IDIQ with DLA Land and Maritime (awarded February 2026, completion February 2031) for battery storage supplies covers the largest contract ceiling in the current portfolio. A single-award $6.53 million IDC with DLA Land and Maritime for Battery Storage NSN 6140-01-560-7240 (through August 2030) has generated substantial task order volume. Additional IDCs include a $1.76 million Other Transaction IDV with PEO Soldier for the Platoon Bulk Charger system (awarded September 2025, no task orders issued to date), a $500,000 single-award IDC for CSEL Battery Adapter J-6769A/P with DLA Land and Maritime (through December 2029), and a $250,000 single-award IDC for cable assemblies with DLA Aviation (through September 2030). Recent representative prime awards include a $1.26 million DLA Land and Maritime purchase order for 3,680 storage batteries (April 2025), a $673,000 delivery order for battery storage (March 2025), a $639,748 delivery order from Army CECOM (December 2024), and a $166,486 purchase order from Naval Sea Systems Command for Li6T military batteries for USMC testing (September 2025). Task orders under parent vehicles typically range from $8,700 to $600,000, with median values between $30,000 and $100,000.

In its subcontractor role, Bren-Tronics supplies batteries, chargers, adapters, and cable assemblies to major defense primes including Lockheed Martin, BAE Systems Technology Solutions & Services, L3Harris Nexgen Communications, Raytheon Company, Northrop Grumman Systems, General Dynamics Land Systems, Leidos, and CACI International. Subcontract work focuses on power management components and batteries for tactical communications systems, autonomous vehicle prototypes, airborne surveillance platforms, and marine platforms.

Activity has remained stable year over year—131 awards in both 2022 and 2023, rising to 180 in 2024, then softening to 116 in 2025 and 22 in the first five months of 2026. Eleven awards (combined potential value $3.3 million) face recompete within the next twenty-four months. The $1.65 billion combined potential value across 2,385 total awards reflects invoiced obligations of $629.6 million (38% of ceiling). Top NAICS categories center on miscellaneous electrical equipment manufacturing (618 awards), primary battery manufacturing (478 awards), and storage battery manufacturing (346 awards), with PSC concentration in rechargeable and nonrechargeable batteries (1,413 awards combined).

Bren-Tronics Defense LLC operates as a child entity within the Enersys Advanced Systems Inc. corporate structure. Enersys Advanced Systems manufactures batteries and power systems and holds its own federal contracting footprint. The parent relationship positions Bren-Tronics as a specialized battery and power component supplier within a broader energy systems manufacturer.
