Prime MP25K37SS – High Rate Semi-Solid Battery cell| 3.7V High Nickel Ternary 280WH/KG | 25,000 mAh

“The thinnest cell in the 105×230mm footprint — 21.7% more energy than the Volt HV Ternary 20,000mAh, in a lighter cell, at 6.7mm.”

The Prime 3.7V High Nickel Ternary 280WH/KG 25,000mAh is the thinnest cell in the entire Prime HN Ternary family and the thinnest cell available in the 105×230mm footprint across all Midlands Power series. At 6.7mm thick and 374g, it stores 92.5Wh — 21.7% more energy than the Volt HV Ternary 20,000mAh cell that shares its footprint, in a cell that is 0.3mm thinner and 6g lighter. This cell is not positioned as a straightforward capacity step within the Prime HN Ternary range — it occupies the 105×230mm format specifically for platforms that require a wide, flat battery profile where bay thickness is the binding constraint and planar dimensions are available. At 6.7mm, it fits battery compartments too shallow for any other Prime HN Ternary cell and any Volt cell at this footprint. It charges at 1C (25A, ~60 minutes), runs 5C continuous (125A) and 10C peak (250A), and carries the full structural and safety advantages of semi-solid construction: lower risk of liquid leakage and fire than conventional liquid-electrolyte cells. Precision-manufactured using AI vision stacking technology for consistent internal structure and reliable field performance across every production batch.

Description

The Prime HN Ternary 25,000mAh is the thinnest cell in the 105×230mm format at just 6.7mm and 374g. It delivers 92.5Wh—21.7% more energy than comparable cells while being lighter and thinner. Designed for ultra-slim battery bays, it supports 1C charging (~60 minutes), 5C continuous, and 10C peak output, with semi-solid construction and AI precision manufacturing for safety and reliability.

  • 6.7mm — Thinnest Cell in the Entire Prime HN Ternary Family

At 6.7mm, the 25,000mAh is the thinnest cell across all seven capacities in the Prime HN Ternary 280WH/KG lineup. The next thinnest is the 16,000mAh at 7.8mm. In the 105×230mm footprint specifically, it is 0.3mm thinner than the Volt HV Ternary 20,000mAh (7.0mm) — the only other sub-8mm cell in this format. For any drone platform with a 105×230mm battery bay where depth is strictly limited, the Prime 25,000mAh is the only cell in this footprint that delivers at under 7mm.

  • 21.7% More Energy Than the Volt HV Ternary 20,000mAh — In a Lighter Cell

The Volt HV Ternary 20,000mAh is the lowest-capacity liquid-electrolyte cell in the 105×230mm footprint, storing 76.0Wh at 380g. The Prime 25,000mAh stores 92.5Wh at 374g — 21.7% more energy in a cell 6g lighter and 0.3mm thinner. For any platform already running the Volt HV Ternary 20,000mAh in a shallow 105×230mm bay where more endurance is needed but thickness cannot increase, this is a direct, same-footprint upgrade that requires no frame modification and improves on every size metric while adding over a fifth more stored energy.

  • A Different Form Factor Proposition — Wide, Flat, Thin

The 25,000mAh exists in the Prime HN Ternary family not as a capacity step between the 22,000mAh and 27,000mAh, but as a form-factor-specific option for platforms that the 87×187mm format cannot serve. The 105×230mm footprint is significantly wider and longer than the 87×187mm bay — but at 6.7mm, it is 3.1mm thinner than the 27,000mAh (9.8mm) and 4.1mm thinner than the 30,000mAh (10.8mm). For fixed-wing UAVs with thin wing-integrated battery compartments, flat-body multi-rotor designs, and platforms where the battery bay is wide and shallow rather than narrow and deep, the 25,000mAh fits where no other Prime HN Ternary cell can.

  • Semi-Solid Construction in the Ultra-Thin Format

The Prime series uses advanced semi-solid electrolyte technology, reducing liquid electrolyte content versus conventional LiPo construction. At 6.7mm, the structural stability benefits of semi-solid construction are particularly relevant: a thinner cell is more susceptible to mechanical stress from vibration and flex loads in the airframe, and the semi-solid electrolyte provides greater internal geometric stability under these conditions than a conventional liquid-electrolyte cell at equivalent thickness. Additionally, the lower risk of liquid leakage and fire under damage or abnormal conditions applies throughout the 25,000mAh’s operational life.

  • 10C Peak — 250A, Calibrated for Endurance Operations

The Prime 25,000mAh delivers 250A peak burst and 125A continuous — rates designed for sustained endurance operations on mapping, logistics, and emergency response platforms. Compared to the 500A peak of the Volt HV Ternary 20,000mAh in the same footprint, the trade-off is clear: the Prime 25,000mAh directs its semi-solid High Nickel Ternary performance advantage into energy density and stored energy, not instantaneous burst power. For platforms where mission duration at the 105×230mm form factor is the primary metric, 10C/250A is appropriate and the 21.7% energy advantage over the Volt HV Ternary 20,000mAh is the specification that matters.

  • 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 27,000mAh and 30,000mAh cells in the Prime HN Ternary family. Three cells in rotation at 1C sustain continuous field operations without waiting, compensating for the longer charge window compared to the 2C cells in the lower Prime HN Ternary range.

  • AI Vision Stacking

Fully automated production line with AI-guided vision stacking ensures precise internal layer alignment and structural integrity across the full 105×230mm footprint — particularly critical at 6.7mm thickness where internal layer precision directly determines both performance consistency and safety behaviour at this ultra-thin form factor.
