Description

The Volt HV Li-Co 28,000mAh is the flagship of the Volt Li-Co series, delivering 106.4Wh in the 87×187mm footprint. It offers the highest capacity in the lineup with strong output performance at 10C continuous and 700A peak. Built on 240Wh/kg high-voltage Li-Co chemistry, it prioritizes maximum energy density for long, heavy-load drone missions, with 2C charging and AI-precision manufacturing for reliability.

• 25C Peak Discharge — 700A Burst

Advanced electrode material formulation delivers 700A of instantaneous burst current — the highest peak output in the entire Volt Li-Co lineup — enabling confident handling of the heaviest payloads, steepest climbs, and most aggressive flight profiles across extended missions.

• 240 WH/KG — Maximum Stored Energy in the Volt Li-Co Family

At 106.4Wh of nominal energy, this is the highest-capacity cell in the Volt Li-Co range. Sharing the same 240WH/KG energy density rating as the 17,000mAh and 22,000mAh variants, it stores 27% more energy than the 22,000mAh (83.6Wh) and 65% more than the 17,000mAh (64.6Wh) — the definitive choice when maximum flight time is the primary objective.

• Same 87×187mm Footprint as the 22,000mAh

The 28,000mAh cell shares the exact same 87×187mm planar footprint as the 22,000mAh variant. The only physical difference is thickness — 11.6mm vs 9.6mm. This means any drone frame bay that fits the 22,000mAh cell can be directly upgraded to the 28,000mAh for a 27% increase in energy without any structural modification.

• 2C Charge Rate — 56A Input

Standard 2C charge delivers 56A input, fully charging the cell in approximately 30 minutes. The 2C charge rate is a characteristic of the high-voltage Li-Co chemistry — a deliberate trade-off for superior energy density and maximum stored energy over fast-charge speed.

• 4.45V High Voltage Platform

Charges to a 4.45V ceiling — higher than standard LiCoO₂ (4.2V) and ternary variants (~4.35V) — enabling more energy to be packed into each charge cycle within the same physical cell size. This extended voltage window is the primary driver of the 240WH/KG energy density across all Volt Li-Co cells.

• AI Vision Stacking

Fully automated production line with AI-guided vision stacking ensures precise internal layer alignment and structural integrity across the full 87×187mm footprint — critical for maintaining consistent performance, safety, and cycle reliability in high-voltage, high-capacity Li-Co cells at this energy level.

• Safe Discharge to 3.6V

The 3.6V safe cutoff reflects the tighter voltage management window of high-voltage Li-Co chemistry — ensuring stable, predictable voltage delivery throughout the full 28,000mAh discharge curve and protecting the cell from damage at deep discharge.
