Enhanced range and efficiency for long-endurance drone platforms

Upgrade Energy Battery Packs for Drones

Upgrade Energy battery packs offer a range of advantages to set them apart from standard commercial Li-Po drone battery solutions.

Engineered for Mission-Specific Performance: Each of Upgrade Energy’s product lines has been designed from the ground up to suit a specific mission requirement – power, balanced efficiency, or endurance. By matching the pack design to the actual duty cycle, this approach delivers superior real-world results for customers.

Premium Cell Selection: Upgrade Energy packs are built on premium cells from leading suppliers such as Amprius and Molicel, selected for their suitability for specific applications.

Engineering-Driven Pack Design: Upgrade Energy’s battery solutions are engineered as complete electrical and mechanical systems, taking into account crucial factors such as resistance, voltage drop, thermal rise, layout and wiring design.

Predictable Integration for OEMs: Designed for use in real-world UAVs and unmanned systems, Upgrade Energy packs provide OEMs and system integrators with consistent electrical and thermal behavior as well as repeatable high performance in specific mission profiles.

Dark Lithium GOLD

The GOLD Series enables space- and weight-constrained UAS platforms to maximize their available flight time without increasing MTOW or battery footprint, unlocking enhanced range and duration for mission-critical applications such as ISR and payload delivery.

Optimized for persistence-focused duty profiles that prioritize total stored energy over high thrust performance, GOLD Series battery packs can also be used to improve payload/endurance tradeoffs by reducing the battery mass needed to achieve a particular flight time.

Dark Lithium GREEN

The GREEN Series is designed for general-purpose multirotor and fixed-wing UAS platforms that require excellent endurance and space optimization without the need for high-discharge power performance.

Offering high energy storage and moderate discharge capabilities in a compact footprint, GREEN Series battery packs ensure stable and repeatable performance across high numbers of charge/discharge cycles. They are highly suited to drone fleet operations with long service life requirements, and are ideal for mapping, surveying, and utilities and infrastructure inspection.

Product Highlights:

Dark Lithium GREEN V2 6S4P 16Ah drone battery GREEN V2 6S4P 16Ah

Commonly used for 10” UAS requiring 45+ min flight time

  • Energy Density: 288Wh/kg
