Description
The Volt HV Li-Co 22,000mAh is the mid-tier cell in the Li-Co series, delivering high energy density (240Wh/kg) in the 87×187mm footprint at 363g. It offers strong performance with 10C continuous and 550A peak discharge, balancing power and efficiency. Designed for heavy-load drone use, it supports 2C charging and uses AI precision manufacturing for consistent reliability.
- 25C Peak Discharge — 550A Burst
Advanced electrode material formulation delivers 550A of instantaneous burst current — a 29% increase over the 17,000mAh entry variant (425A) — enabling confident handling of heavier payloads, steeper climbs, and more aggressive flight profiles.
- 240 WH/KG — Highest Energy Density in the Volt Lineup
Sharing the same 240WH/KG rating as all Volt Li-Co cells, this variant stores 83.6Wh of nominal energy — 29% more than the 17,000mAh (64.6Wh) — while adding only 79g of weight. The Li-Co chemistry delivers more energy per gram than any other Volt material system.
- Thinnest in the Volt Li-Co Family — 9.6mm
At 9.6mm thickness, this is the slimmest cell in the entire Volt Li-Co lineup — thinner than both the 17,000mAh (10.0mm) and the 28,000mAh (11.6mm). The 87×187mm footprint combined with a slim profile makes it highly versatile across mid-size drone frame designs.
- 2C Charge Rate — 44A Input
Standard 2C charge delivers 44A input, fully charging the cell in approximately 30 minutes. The 2C rate is a characteristic of the high-voltage Li-Co chemistry — a deliberate trade-off for superior energy density 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, directly contributing to the 240WH/KG rating.
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 and safety in high-voltage Li-Co cells.
The 3.6V safe cutoff reflects the tighter voltage management window of high-voltage Li-Co chemistry — ensuring stable, predictable voltage delivery throughout discharge and protecting the cell from damage at deep discharge.

Why the 22,000 mAh is the Sweet Spot
| Reason |
Detail |
| Thinnest in family |
9.6mm vs 10.0mm (17k) and 11.6mm (28k) — slimmest profile |
| Best weight-to-energy ratio |
83.6Wh at 363g — more efficient than 17k (64.6Wh/284g) and 28k (106.4Wh/460g) |
| 29% more energy than 17k |
For only 79g more weight — excellent incremental efficiency |
| Same footprint as 28k |
87×187mm shared with 28k — same drone frame bay, lower weight |
| Mid-range peak power |
550A peak — strong enough for heavy missions, lighter than 28k |
