Description

The Max 3.7V High Nickel Ternary 320WH/KG 25,000mAh delivers 92.5Wh — the highest energy in the 72×170mm format. It outperforms all comparable cells with more energy in a smaller, lighter design. It supports 1C charging, 3C continuous, and 5C peak, making it the top option for this footprint.

• 92.5Wh — The Absolute Energy Ceiling of the 72×170mm Format

The Max 25,000mAh stores 92.5Wh — more than every cell from every series in the 72×170mm footprint. The Prime HN Ternary 22,000mAh is the closest competitor at 81.4Wh. The Prime SHV LCO 17,000mAh stores 67.2Wh. The Volt HV Li-Co 17,000mAh stores 64.6Wh. No current cell in any series surpasses 92.5Wh in the 72×170mm format. For any drone platform built around the 72×170mm bay where maximum flight time is the primary design objective, the Max 25,000mAh is the endpoint — the most energy this footprint delivers.

• 320WH/KG — 13.6% More Energy Than the Prime HN Ternary 22,000mAh for 6g More Weight

The Prime HN Ternary 22,000mAh is the highest-energy Prime cell in the 72×170mm footprint: 81.4Wh at 294g, 10.3mm, 280WH/KG. The Max 25,000mAh stores 92.5Wh at 300g, 10.8mm, 320WH/KG — 13.6% more energy for 6g more weight and 0.5mm more thickness. Six grams separate these two cells in the same bay. The 11.1Wh difference it buys translates directly into extended flight time on any endurance platform. This is the 320WH/KG vs 280WH/KG advantage expressed at its most concentrated — the same footprint, the same approximate weight class, 13.6% more energy.

• Same Energy as the Prime HN Ternary 25,000mAh — 74g Lighter, Smaller Footprint

The Prime HN Ternary 25,000mAh stores 92.5Wh — identical to the Max 25,000mAh — but in the 105×230mm footprint at 374g. The Max 25,000mAh delivers the same 92.5Wh in the 72×170mm footprint at 300g — 74g lighter and in a bay that is 37mm narrower and 60mm shorter. For platforms that can accommodate the 72×170mm form factor, the Max 25,000mAh reaches the same stored energy as a 105×230mm Prime cell while saving 74g and fitting into a significantly smaller bay.

• The Ceiling of the 72×170mm Max Format

The 25,000mAh is the last Max cell in the 72×170mm footprint. The next step in the Max family — the 32,000mAh — requires the 87×187mm bay. For operators committed to the 72×170mm format who need every watt-hour the Max series can deliver at this footprint, the 25,000mAh is the definitive destination. There is no higher Max HN Ternary capacity in this bay.

• 25.0% More Energy Than the Max 20,000mAh — Final 72×170mm Step-Up

Stepping up from the Max 20,000mAh adds 18.5Wh of stored energy (+25.0%) and increases peak burst from 100A to 125A (+25.0%) for 55g of additional weight and 2.0mm of additional thickness — all within the same 72×170mm footprint. This is the last capacity step available in the Max series before the footprint changes. For operators already running the Max 20,000mAh who need the maximum endurance the 72×170mm bay can deliver in this chemistry, the 25,000mAh is the direct upgrade with no frame modification required.

• 320WH/KG — New Solid-State Technology at the Energy Ceiling

The Max series achieves 320WH/KG through new high specific capacitance electrode materials and advanced semi-solid packaging technology — the manufacturer’s described new solid-state technology advance delivering industry-leading energy density in the semi-solid cell category. At the 92.5Wh energy level of the 25,000mAh, this technology delivers the highest stored energy available in the 72×170mm format from any series. The semi-solid electrolyte construction reduces liquid electrolyte content versus conventional LiPo construction, providing lower risk of liquid leakage and fire, greater mechanical stability under vibration and impact loads, and more consistent internal geometry across the cell’s operational life.

• The Max Series Rate Architecture — Maximum Density, Calibrated Rates

The Max series operates on a 1C charge / 3C continuous / 5C peak rate profile — consistent across every cell in the lineup. At the 25,000mAh level, these rates deliver 25A charge input, 75A continuous, and 125A peak. For mapping, logistics, emergency response, and fire-fighting UAVs where motor loads during cruise and standard operations fall within the 3C/75A continuous range and peak events do not require more than 5C/125A, this profile is entirely appropriate and the 320WH/KG energy density advantage is the decisive specification. For platforms requiring 10C or 25C peak capability, the Prime or Volt series is the correct choice.

• 1C Charge — 25A Input, ~60 Min Full Charge

Standard 1C continuous charge delivers 25A input, fully charging the cell in approximately 60 minutes — consistent with the Max 20,000mAh and all cells in the Max series. Three cells in rotation at 1C sustain continuous field operations without waiting, compensating for the longer charge window relative to the 2C cells in the Prime and Volt series.

• High-Precision Manufacturing — Electrode Preparation and Stacking

Automated, high-precision electrode preparation combined with advanced stacking and encapsulation technique ensures consistent internal structure and reduces performance fluctuations across every production batch. At the 320WH/KG energy density ceiling of the 72×170mm format, manufacturing precision in electrode preparation and layer alignment is directly responsible for both energy density realisation and long-term cell reliability at this maximum energy point.
