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 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.

TECHNOLOGY COMPARISON
Semi-Solid vs LiPo for Heavy-Lift Missions
| Performance Factor | Voltsky Semi-Solid | Standard LiPo |
|---|---|---|
| Max Continuous Discharge | 15C (sustained) | 10–12C (derate above 8C) |
| Heat at High Current | Stable below 55°C | Spikes to 70°C+, BMS cutoff |
| Cycle Life | 500+ cycles | 200–300 cycles |
| Energy Density | Higher Wh/kg ratio | Standard |
| Puncture / Crush Safety | Semi-solid = no liquid electrolyte leak | Fire/smoke risk on puncture |
| Annual Replacement Cost | ~40% lower for 60-cycle/month fleets | High |
