Heavy Lift & Delivery
High-Energy Batteries for Maximum Payload Drones
When your drone carries 30–50 kg, battery failure is not an option. Voltsky heavy-lift semi-solid state batteries deliver sustained high-current discharge with industry-leading cycle life — built for commercial delivery and industrial logistics.

Heavy Lift Operations Demand More from Every Cell
High-C Discharge Heats Up Cells
Carrying 30+ kg means drawing 150A+ continuously. Standard LiPo cells heat to dangerous levels within 8 minutes — triggering BMS cutoff mid-delivery.
Battery Cost Dominates ROI
Delivery drones run 40–60 cycles per month. At 300-cycle LiPo life, you replace packs every 5–7 months. Voltsky's 500+ cycle life cuts replacement frequency by 40%.
Weight vs Energy Trade-off
Every gram of battery is a gram less payload. Our cells achieve higher energy density than conventional LiPo — giving you more usable capacity per kilogram of battery weight.

Heavy-Lift Drone Battery — Frequently Asked Questions
What is the maximum capacity semi-solid state battery you supply for heavy-lift delivery drones?
Our current maximum is the VS-HL-8S-25000 (25,000mAh, 29.6V), which delivers 745 Wh — sufficient for 18–22 minutes at full payload on a 30–40 kg delivery platform. For higher voltage requirements, the VS-HL-12S-18000 (44.4V) offers superior efficiency at altitude. Custom configurations up to 30,000mAh and 14S voltage are available as a UAV battery supplier for OEM customers.
How do your batteries handle 15C continuous discharge without overheating?
Our semi-solid electrolyte architecture is fundamental to high-C thermal management. Unlike liquid LiPo cells that heat to 70°C+ at sustained 10C+ discharge, our semi-solid state UAV batteries remain stable below 55°C at 15C continuous. This is achieved through the semi-solid electrolyte's superior ionic transport efficiency, which reduces resistive heat generation. We provide tested discharge-temperature data curves for all heavy-lift battery models.
Are your batteries certified for commercial UAV delivery operations?
Yes. All Voltsky heavy-lift UAV batteries carry UN38.3 (required for air transport), CE, RoHS, and MSDS certification. IEC62133 is available for customers requiring it for regulatory or insurance compliance. We also provide nail penetration test results showing no flame or explosion response — increasingly required by commercial drone delivery insurance policies in Europe and North America.
What is the minimum order quantity for heavy-lift battery OEM/ODM supply?
MOQ varies by configuration and customization level. For standard models (VS-HL series), MOQ starts at 20 units. For custom OEM/ODM configurations with specific form factors, connectors, or BMS parameters, MOQ and lead time are agreed per project. We work with logistics drone OEMs from prototype stage (10–20 units) through mass production. Contact our team with your volume forecast and timeline.
What makes semi-solid state better than LiPo for high-frequency delivery operations?
For delivery drones running 40–60 cycles per month, the 500+ cycle life of our semi-solid UAV batteries cuts annual replacement cost by ~40% versus standard LiPo at 200–300 cycles. Combine this with safer high-C discharge behavior, no thermal runaway below 80°C, and lower battery weight per Wh — and the total cost of ownership advantage compounds significantly over a 2–3 year fleet deployment.
