## Competitive Positioning

Leolus Energy is the ONLY Indian drone battery manufacturer offering semi-solid state chemistry with a branded product line (Nexfly). All other Indian battery manufacturers in the drone segment use standard LiPo or Li-ion chemistry, delivering ~150–200 Wh/kg versus Leolus's ~338 Wh/kg at pack level.

Key advantages over any standard LiPo or Li-ion drone battery:
* 75–133% higher energy density (~338 vs 150–200 Wh/kg)
* 2–5x longer cycle life (300–500 vs 100–200 cycles)
* Superior thermal stability — no thermal runaway risk from solid electrolyte
* Wider operating temperature range (-20°C to +60°C vs 15–40°C for LiPo)
* South India manufacturing — fastest delivery to Bangalore, Hyderabad, Chennai, Kerala ecosystems
