Description
The Prime HN Ternary 17,000mAh offers 62.9Wh at 225g in a slim 8.2mm design, providing a highly efficient step up from the 16k with just minimal added weight and size. It supports 2C charging (~30 minutes), 7C continuous, and 10C peak output, combining high energy density, semi-solid safety, and consistent AI-driven manufacturing.
- 280WH/KG — 62.9Wh in 225g
The High Nickel Ternary semi-solid cathode delivers 280WH/KG — storing 62.9Wh in a cell weighing 225g. At 3.7V × 17Ah, the nominal energy figure cross-validates the manufacturer’s stated energy density to within 0.1%: 62.9Wh ÷ 0.225kg = 279.6Wh/KG. For operators sizing battery weight against flight time budgets, this cell delivers the highest energy per gram available in the 72×170mm footprint across all Midlands Power series.
- The Most Efficient Step-Up in the 72×170mm Prime Group
The gap between the 16,000mAh and 17,000mAh is, by design, the smallest increment in the Prime family: +6.25% energy, +6.25% peak current, +10g, +0.4mm. No other step between adjacent cells in the Prime 280WH/KG lineup offers this combination of meaningful energy gain and near-negligible weight addition. For operators already running the 16k who need slightly more endurance without any meaningful change to all-up weight or frame bay fit, the 17,000 mAh is a direct, no-compromise upgrade — same footprint, same chemistry, same charge behaviour, 10g more.
- 59g Lighter Than the Same-Capacity Volt HV Li-Co 17,000mAh
Compared to the Volt HV Li-Co 17,000mAh cell in the same 72×170mm footprint — the most energy-dense liquid-electrolyte option at this capacity — the Prime 17,000mAh is 59g lighter (225g vs 284g), 1.8mm thinner (8.2mm vs 10.0mm), and stores near-identical energy (62.9Wh vs 64.6Wh, a 2.7% difference attributable to the 3.7V vs 3.8V voltage platform). The only trade-off is peak discharge rate: the Volt delivers 25C/425A peak, the Prime delivers 10C/170A. For endurance missions where peak burst is not the primary requirement, the Prime 17,000mAh is the lighter, thinner, structurally safer choice at this capacity point.
- Semi-Solid Construction — Structural Safety Advantage
The Prime series uses advanced semi-solid electrolyte technology, reducing liquid electrolyte content versus conventional LiPo construction. This delivers lower risk of liquid leakage and fire under damage or abnormal conditions, greater mechanical stability under the vibration and impact loads of commercial drone operations, and more consistent internal geometry over the cell’s service life. For mapping, logistics, emergency response, and safety-defence UAVs operating in challenging environments, the semi-solid construction is a meaningful operational advantage over equivalent liquid-electrolyte cells.
- 10C Peak — 170A, Calibrated for Endurance Missions
The Prime 17,000mAh delivers 170A peak burst and 119A continuous — rates designed for sustained endurance operations rather than the high-burst agricultural and training profiles of the Volt series. This is the deliberate architecture of the Prime platform: semi-solid High Nickel Ternary technology directs its performance advantage into energy density, not peak discharge rate. For mapping drones, logistics UAVs, and emergency response platforms where mission duration is the primary metric, 10C/170A peak is fully appropriate and the 280WH/KG density advantage is decisive.
- 2C Charge — 34A Input, ~30 Min Full Charge
Standard 2C continuous charge delivers 34A input, fully charging the cell in approximately 30 minutes. Consistent with the 16k and 22k cells in the same 72×170mm Prime group, the 2C charge rate reflects the semi-solid High Nickel Ternary chemistry’s approach to stable, controlled cycling. Two cells in rotation sustain continuous field operations across extended deployment windows.
- AI Vision Stacking
Fully automated production line with AI-guided vision stacking ensures precise internal layer alignment and structural integrity throughout the 72×170mm footprint — maintaining consistent energy density performance and safety behaviour across every production batch of this high-nickel semi-solid cell.
