Max MPHD35K37SS1 – High Density Semi-Solid Battery cell| 3.7V High Nickel Ternary 320WH/KG | 35,000 mAh

“The 320WH/KG flagship — 129.5Wh in the 87×187mm footprint, 16.7% more energy than the Prime HN Ternary 30,000mAh for 4g more weight.”

The Max 3.7V High Nickel Ternary 320WH/KG 35,000mAh is the flagship of the Max 320WH/KG series — the highest capacity, highest stored energy, highest peak current, and highest continuous output of all four cells in the 320WH/KG lineup. At 410g and 11.0mm in the 87×187mm footprint, it stores 129.5Wh — 16.7% more energy than the Prime HN Ternary 30,000mAh (111.0Wh) for only 4g more weight and 0.2mm more thickness. Against the Prime SHV LCO 28,000mAh at the same 410g, it delivers 17.1% more stored energy. Stepping up from the Max 32,000mAh, it adds 9.4% more energy (118.4Wh to 129.5Wh) and 9.4% more peak burst (160A to 175A) for 30g and 0.4mm within the same footprint. One important context for buyers: the Max 350WH/KG series includes a 35,000mAh cell in the same 87×187mm footprint that stores identical energy at 385g and 9.8mm — 25g lighter and 1.2mm thinner. Operators for whom weight and thickness are the primary constraint alongside this energy level should evaluate the 350WH/KG 35,000mAh alongside this cell. For operators already committed to the 320WH/KG platform, this is its definitive ceiling. It charges at 1C (35A, ~60 minutes), runs 3C continuous (105A) and 5C peak (175A), and is precision-manufactured using high-precision automated electrode preparation, stacking, and encapsulation for consistent internal structure and reliable field performance across every production batch.

Description

The Max 3.7V High Nickel Ternary 320WH/KG 35,000mAh is the flagship of the 320WH/KG series, delivering 129.5Wh in the 87×187mm format. It provides 16.7% more energy than the Prime 30,000mAh for nearly the same size and weight. Compared to the 32,000mAh version, it offers higher energy and peak output (175A). It supports 1C charging, 3C continuous, and 5C peak, making it the top-performing cell in the 320WH/KG lineup.

  • Flagship of the Max 320WH/KG Series — Maximum Across Every Metric

The 35,000mAh leads the Max 320WH/KG family across every performance metric: highest capacity (35,000mAh), highest stored energy (129.5Wh), highest peak burst (175A), and highest continuous output (105A) across all four cells in the lineup. It is the definitive maximum expression of the 320WH/KG semi-solid platform in the 87×187mm format — the ceiling of what this chemistry and cell architecture delivers before the series transitions to the 350WH/KG tier.

  • 16.7% More Energy Than the Prime HN Ternary 30,000mAh — 4g More Weight

The Prime HN Ternary 30,000mAh is the highest-capacity 280WH/KG cell in the 87×187mm footprint: 111.0Wh at 406g, 10.8mm. The Max 35,000mAh stores 129.5Wh at 410g, 11.0mm — 16.7% more energy for 4g more weight and 0.2mm more thickness. Four grams is within the calibration tolerance of most drone weight budgets. The 18.5Wh energy difference it produces is the most concentrated expression of the 320Wh/KG vs 280Wh/KG advantage across the entire 87×187mm format: near-identical weight and thickness, 16.7% more energy.

  • Same Weight as the Prime SHV LCO 28,000mAh — 17.1% More Energy

The Prime SHV LCO 28,000mAh weighs 410g and stores 110.6Wh on the 3.95V platform. The Max 35,000mAh weighs 410g and stores 129.5Wh on the 3.7V platform — at exactly equal weight, the Max 35,000mAh delivers 17.1% more stored energy. For operators in the 87×187mm format choosing between maximum energy and voltage platform, these two cells represent the direct trade-off: 3.95V with 110.6Wh, or 3.7V with 129.5Wh, both at 410g.

  • 50g Lighter Than the Volt HV Li-Co 28,000mAh — 21.7% More Energy

The Volt HV Li-Co 28,000mAh stores 106.4Wh in 460g at 11.6mm with a 25C/700A peak on a liquid-electrolyte platform. The Max 35,000mAh stores 129.5Wh in 410g at 11.0mm — 50g lighter, 0.6mm thinner, 21.7% more energy. The only specification where the Volt HV Li-Co 28,000mAh leads is peak discharge: 25C/700A versus the Max’s 5C/175A. For endurance platforms where sustained mission duration is the design objective and 700A burst is not required, the Max 35,000mAh replaces the Volt HV Li-Co 28,000mAh in the same bay with more energy, less weight, thinner profile, and semi-solid construction.

  • The 320WH/KG vs 350WH/KG Decision at 35,000mAh

The Max series also produces a 35,000mAh cell in the 350WH/KG tier — the same capacity and same 87×187mm footprint, storing identical 129.5Wh, at 385g and 9.8mm. Against the 320WH/KG 35,000mAh, the 350WH/KG variant is 25g lighter and 1.2mm thinner for the same stored energy. For operators for whom the 35,000mAh is the target capacity and weight or thickness reduction is the priority alongside this energy level, the 350WH/KG 35,000mAh is the appropriate evaluation. For operators already committed to the 320WH/KG platform — having stepped through the 20,000mAh, 25,000mAh, and 32,000mAh cells — this cell is the natural and consistent endpoint of that platform.

  • 9.4% More Energy Than the Max 32,000mAh — Final 87×187mm Step-Up

Stepping up from the Max 32,000mAh adds 11.1Wh of stored energy (+9.4%) and increases peak burst from 160A to 175A (+9.4%) for 30g of additional weight and 0.4mm of additional thickness — all within the same 87×187mm footprint. This is the last capacity step within the Max 320WH/KG family. For operators who have committed to the 320WH/KG platform and require the maximum endurance it delivers in the 87×187mm bay, the 35,000mAh is the direct, no-modification endpoint from the 32,000mAh.

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

The Max series achieves 320WH/KG through new high specific capacitance electrode materials and advanced semi-solid packaging technology — described by the manufacturer as new solid-state technology delivering industry-leading energy density. 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. At 129.5Wh — the ceiling of the 320WH/KG platform — the semi-solid safety advantage is at its most significant.

  • 5C Peak — 175A, 3C Continuous — 105A

The Max 35,000mAh delivers 175A peak burst and 105A continuous — the highest peak and continuous outputs of any cell in the Max 320WH/KG family. For mapping, logistics, emergency response, and fire-fighting UAVs where motor loads fall within the 3C/105A continuous range and peak events do not exceed 5C/175A, these rates serve the endurance-first mission profile this cell is designed for with appropriate headroom for standard takeoff, climb, and payload operations.

  • 1C Charge — 35A Input, ~60 Min Full Charge

Standard 1C continuous charge delivers 35A input — the highest absolute charge current in the Max 320WH/KG family — fully charging the cell in approximately 60 minutes. Consistent with every cell in the Max series. Three cells in rotation at 1C sustain continuous field operations at the maximum endurance level the 320WH/KG platform delivers.

  • 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. At 129.5Wh — the highest energy point of the Max 320WH/KG series — manufacturing precision in electrode preparation and layer alignment is the direct determinant of peak energy density realisation, safety behaviour, and production consistency across every batch.
