Why Choose the Midlands Power 8,000mAh Ultra Ternary Battery?
600A Peak — Highest Instantaneous Burst Current in the Entire Ultra Catalog
Advanced electrode material formulation and the wide 70×140mm planar geometry deliver 600A of instantaneous peak burst current at 75C — the highest absolute peak current of any cell across the entire Ultra Ternary lineup, at any format or capacity. Against every other cell in the catalog:
- 128A more than the 43×128mm 6,300mAh (472A)
- 300A more than the 43×128mm 4,000mAh (300A)
- 210A more than the 34×96mm 3,000mAh (390A)
For motor and ESC configurations requiring above 472A instantaneous current, this is the only Ultra Ternary cell that delivers it.
29.60Wh — Highest Stored Energy in the Entire Ultra Ternary Catalog
At 29.60Wh, the 8,000mAh stores more energy than any other Ultra Ternary cell across all formats and capacities:
- 6.29Wh more than the 43×128mm 6,300mAh (23.31Wh)
- 10.36Wh more than the 43×128mm 4,000mAh (14.80Wh)
- 18.50Wh more than the 34×96mm 3,000mAh (11.10Wh)
For large-frame FPV and racing platforms where maximum run duration alongside maximum peak current defines performance, 29.60Wh is the largest energy reservoir the Ultra Ternary architecture delivers.
7.9mm — 3.0mm Thinner Than the 43×128mm 6,300mAh Despite 27% More Energy
The 70×140mm planar footprint distributes 8,000mAh of electrode material across significantly more surface area than the 43×128mm format allows, enabling thinner stacking at substantially higher energy. At 7.9mm, the 8,000mAh is 3.0mm thinner than the 43×128mm 6,300mAh (10.9mm), despite storing 27% more energy and delivering 128A more peak current. For large-frame platforms where bay depth is a constraint, this cell provides the entire catalog’s maximum energy in a flat, low-profile form factor that distributes weight evenly across the full 70×140mm bay area.
27% More Energy Than the 43×128mm 6,300mAh — The Final Format Step
Stepping from the 43×128mm 6,300mAh to the 70×140mm 8,000mAh adds 6.29Wh of stored energy (+27.0%) and raises peak burst from 472A to 600A (+27.1%), in a cell that is 3.0mm thinner — at the cost of 40g of additional weight and a wider, longer bay. For large-frame builders who have maximized the 43×128mm format and need more energy and more peak current, the 8,000mAh provides both in a thinner profile.
Ceramic Separator and PVDF Electrode — Racing-Grade Construction at Maximum Output
Industry-first ceramic separator and PVDF electrode construction deliver the thermal resistance and structural integrity required at the most demanding output levels in the Ultra lineup. At 600A peak and 280A continuous from a 177g, 7.9mm cell across a 70×140mm electrode area, the ceramic separator’s thermal performance and the PVDF binder’s structural stability under combined sustained and burst load are at their most critical application across the entire catalog. The result is long cycle life and consistent performance across hundreds of charge-discharge cycles at these output levels.
The Absolute Endpoint of the Ultra Series and the Midlands Power Catalog
The 8,000mAh is the final cell in the Ultra series and the final product in the Midlands Power catalog. The entire progression — from the 17g 30×48mm 500mAh entry through the 20-series, 34-series, and 43×128mm family — has built toward platforms that need exactly what this cell provides. There is no higher-specification Ultra cell. For large-frame competitive racing platforms where 600A peak, 280A continuous, and 29.60Wh simultaneously define the build requirement, this is the answer.

An Honest Note on Continuous Output
The 8,000mAh delivers 280A continuous at 35C — 4A below the 43×128mm 6,300mAh’s 284A at 45C. This 1.4% difference is not operationally significant for the vast majority of large-frame racing platforms. It is an accurate figure and stated transparently. For any platform requiring sustained current above 284A, no Ultra Ternary cell meets that specification. For platforms where 280A continuous, 600A peak, and 29.60Wh define the requirement, this is the only cell in the lineup that delivers all three simultaneously.
Charging: 2C / 16A — Full Charge in ~30 Minutes
The 2C continuous charge rate delivers 16.0A input — the highest absolute charge current in the entire Ultra Ternary catalog and the highest of any cell in the Midlands Power lineup — fully charging the cell in approximately 30 minutes. Running multiple cells in rotation at 2C sustains back-to-back racing sessions at the maximum energy and peak current level the Ultra Ternary architecture provides.
Ideal Applications
Large-frame FPV racing drones — 600A peak and 29.60Wh are the absolute peak and energy ceiling of the Ultra Ternary catalog for the largest competitive racing builds.
Full-size RC cars requiring above 472A peak — the only Ultra Ternary cell delivering above 472A instantaneous burst output, in the 70×140mm format.
Large-scale RC aircraft — 29.60Wh at 7.9mm in the 70×140mm footprint, maximum energy at a thinner profile than the 43×128mm ceiling.
RC boats with maximum motor configurations — 280A continuous and 600A peak for the highest-output hull motor setups in the Ultra Ternary lineup.
43×128mm 6,300mAh upgrade builds — 27% more energy, 128A more peak, 3.0mm thinner for 40g more weight, in a new 70×140mm bay.
Ultra series flagship build — the definitive final cell of the entire Ultra lineup and the absolute endpoint of the Midlands Power battery cell catalog.
Product Summary
The Midlands Power 3.7V Ternary 8,000mAh is the final cell in a catalog of 48 products spanning four series, 11 voltage platforms, and 21 form factors. It closes the Ultra lineup with two absolute records: the highest instantaneous peak current (600A) and the highest stored energy (29.60Wh) of any Ultra Ternary cell. In a 7.9mm profile — 3.0mm thinner than the previous format ceiling — it delivers both simultaneously. For large-frame competitive platforms at the top end of the racing spectrum, this is the maximum the Ultra Ternary architecture provides.
