Description
The Volt HV Ternary 20,000mAh is the slimmest high-capacity cell in the Volt series at just 7.0mm thickness in the 105×230mm footprint. It delivers strong endurance with 25C peak discharge and 5C fast charging, making it ideal for compact drone designs needing long flight time. Built with AI precision manufacturing for consistent performance and reliability.
- 25C Peak Discharge
Advanced electrode material formulation delivers a 500A burst current — sufficient to handle sudden payload lifts, aggressive climb angles, and high-torque motor spikes without voltage sag.
- 5C Fast Charge
100A continuous charge input brings the cell from flat to full in approximately 12 minutes. Two cells in rotation can sustain uninterrupted all-day field operations.
- Thinnest in the Family — 7.0mm
At just 7.0mm thickness, this is the flattest cell in the entire Volt 3.8V Ternary lineup. Despite a wider 105×230mm footprint, it opens up unique stacking and integration possibilities for flat-frame drone builds where vertical space is the limiting constraint.
- AI Vision Stacking
Fully automated production line with AI-guided vision stacking ensures precise internal layer alignment, structural integrity, and cell-to-cell consistency — critical for large-format cells like this one.
- 75°C Heat Resistance
High-voltage ternary chemistry handles operating temperatures up to 75°C, ensuring reliable performance in hot outdoor environments and continuous heavy-load cycles.
- Safe Deep Discharge to 3.3V
A lower safe cutoff of 3.3V gives a wider usable energy window compared to lithium cobaltate variants (3.5V–3.6V), maximizing effective capacity per charge cycle.
