Sri Lanka's rapidly evolving technological infra-structure demands high-density, thermally resilient portable power sources. As unmanned aerial vehicles (UAVs) expand from agricultural top-dressing across the Central Highlands (Nuwara Eliya, Kandy) to coastal surveillance across the Indian Ocean maritime zone, the operational pressure placed on battery chemistry has escalated exponentially. Traditional off-the-shelf lithium-polymer (LiPo) batteries suffer rapid thermal degradation under Sri Lanka’s ambient tropical conditions, where humidity levels frequently surpass 85% RH and field temperatures reach up to 38°C in districts like Hambantota and Trincomalee.
To overcome the limitations of standard power units, our OEM battery factory delivers custom-engineered lithium-ion (Li-ion), Lithium Iron Phosphate (LiFePO4), and ultra-light Solid-State battery packs engineered specifically for high-rate continuous discharge (15C–30C peak) alongside modular Container Energy Storage Systems (BESS). These power modules function seamlessly both as aerial flight packs and as heavy-duty ground station support units charging commercial drone fleets in real-time.
Delivering sustained 25C continuous discharge and 50C burst power, essential for payload-heavy agricultural spraying drones operating over steep mountain slopes.
Integrated cooling plates within 100kW–5MWh containerized stations prevent thermal runaway under intense equatorial solar radiation.
Marine-grade aluminum and conformal-coated PCB components built to resist salt air degradation along Sri Lanka's 1,340 km coastline.
Providing genuine information gain requires mapping electrochemical parameters directly to real-world geography and sector needs. Our factory exports specialized battery packs designed to solve critical operational bottlenecks faced by Sri Lankan enterprises, state utility boards, and drone service providers:
The central hill country presents rugged terrain where ground tractor access is impossible. UAV heavy-lifters carrying 30L–50L fertilizer payloads require ultra-lightweight packs with high energy density (Wh/kg). Our multi-rotor battery packs maintain stable voltage curves up to 90% Depth of Discharge (DoD), preventing voltage sags during vertical climbs in altitude-dense fields.
Fixed-wing VTOL (Vertical Take-Off and Landing) UAVs utilized by maritime security teams demand extended flight endurance (2.5 to 4 hours). By deploying semi-solid-state lithium pouch cell assemblies, we boost payload capacity while retaining structural resistance against turbulence and high winds in coastal zones such as Galle and Jaffna.
The Port of Colombo and the Hambantota International Port are global maritime hubs requiring uninterrupted automated operations. Our containerized energy storage units (233kWh to 5MWh) serve as mobile fast-charging hubs for heavy industrial drones, automated guided vehicles (AGVs), and emergency backup systems during local utility grid fluctuations.
