What d-ESPAT Pvt Ltd does

D-ESPAT Pvt Ltd is a Chennai-based private limited design house that designs and integrates custom lithium-ion and lithium-polymer battery packs with battery management systems (BMS), mechanical enclosures, and chargers for mission-critical applications. Its customer base spans Indian defence research laboratories (IRDE, NSTL, NIOT), defence forces, and industrial clients in electric vehicles, underwater/marine robotics, medical, telecom, and energy storage. Named programmes include the Weapon Mounted Thermal Sight battery pack for IRDE, BMS for underwater 58V/120Ah packs for NSTL, Polar ROV batteries for NIOT, the BOSS border surveillance system, and ARAI/ICAT-certified commercial-vehicle battery packs.

The company operates a proprietary BDMO (Battery Design for Manufacturing & Optimization) methodology that it uses to engineer packs for manufacturing efficiency and cost. Differentiated products include JSS55555 MIL-STD-certified battery packs (84V/200AH, Jerry Can e-Fuel 29.4V/75Ah, Parallel Cascader) and aviation ground-support units such as the Helicopter Ground Start Battery (2.2 kWh Li-Polymer, 1400A peak) and the Turborator jet-engine start system (4.2 kWh Li-Polymer). Across its history the company reports 300+ concept studies, 70+ production projects, 180+ demonstration projects, 12+ military-certified and inducted systems, and 300+ clients, with 13+ years of DSIR-recognised in-house R&D.

Revenue is generated through custom hardware sales of bespoke battery packs and a Design for Manufacturing & Optimization professional-services engagement. Pricing is quote-based and consultative, anchored on multi-year contracts with government defence and industrial buyers; no public pricing exists. Go-to-market is enterprise field sales — direct engagement with defence labs, defence forces, and industrial customers, supplemented by an inbound custom-battery inquiry form on the company website and selective participation in industry events (most recently the Malaysia Aerospace Summit 2026). The company is privately held and founder-operated, with no disclosed institutional funding, parent company, or material M&A activity.
