Description

The highest sustained output of any cell in the entire Ultra Ternary catalog. The 3.7V Ternary 6,300mAh delivers 284A continuous and 472A peak from a 137g, 10.9mm soft pack in the 43×128mm format — the absolute performance ceiling of this footprint across every specification it measures. Built for full-size FPV racing drones, RC cars, RC aircraft, and RC boats where maximum sustained current and maximum energy in the 43×128mm bay are the non-negotiable build requirements.

Why Choose the Midlands Power 6,300mAh Ultra Ternary Battery?

284A Continuous — The Highest Sustained Output in the Entire Ultra Ternary Lineup

At 45C continuous from 6,300mAh, this cell delivers 284A of sustained output — more than any other Ultra Ternary cell at any format or capacity, including the 70×140mm 8,000mAh flagship above it in the catalog (35C × 8.0Ah = 280A). The full continuous current progression of the Ultra lineup puts this achievement in context:

For motor and ESC configurations operating at sustained draws above 234A during extended full-size racing runs, the 6,300mAh is the only cell in the entire Ultra Ternary catalog that meets and exceeds this requirement.

 

472A Peak — Highest Instantaneous Burst Current in the 43×128mm Format

Advanced electrode material formulation and the 43×128mm geometry deliver 472A of instantaneous peak burst current at 75C — the highest absolute peak current the 43×128mm format produces. Against every other cell in the family:

• 82A more than the 5,200mAh (390A)
• 172A more than the 4,000mAh (300A)

For full-size competitive racing platforms where peak motor demands exceed 390A, the 6,300mAh is the definitive endpoint in this format.

 

23.31Wh — Highest Stored Energy in the 43×128mm Format

At 23.31Wh, the 6,300mAh stores more energy than any other cell in the 43×128mm family:

• 4.07Wh more than the 5,200mAh (19.24Wh)
• 8.51Wh more than the 4,000mAh (14.80Wh)

That equates to approximately 21% longer potential run time than the 5,200mAh at equivalent power draw — the largest absolute energy reserve the 43×128mm footprint delivers.

 

The Ceiling of the 43×128mm Format — Maximum Everything

The 6,300mAh is the highest capacity available in the 43×128mm footprint. There is no higher capacity, no higher continuous output, no higher peak current, and no higher stored energy in this bay. The next cell in the Ultra Ternary lineup — the 70×140mm 8,000mAh — requires a fundamentally larger footprint. For any build where the 43×128mm bay is the fixed constraint, the 6,300mAh is the definitive endpoint with no frame modification required.

 

The Most Physically Efficient Step in the 43×128mm Family

The final capacity step within the 43×128mm format is also its most weight and thickness-efficient:

The ceiling step costs less weight and less thickness than the step before it, while still delivering over a fifth more energy and 50A more continuous output. For builds where the 5,200mAh’s 234A continuous or 390A peak is the binding constraint, the 6,300mAh is the most physically efficient path to the maximum the format delivers.

 

Ceramic Separator and PVDF Electrode — Racing-Grade Construction at Peak Output

Industry-first ceramic separator and PVDF electrode construction deliver the thermal resistance and structural integrity required at the highest output levels the 43×128mm format produces. At 472A peak and 284A continuous — the simultaneous ceiling of both peak and sustained current in this format — the ceramic separator’s thermal performance and the PVDF binder’s electrode structural stability are at their most critical application across the entire 43×128mm family. The result is consistent performance and long cycle life across hundreds of high-rate charge-discharge cycles in the most demanding full-size racing environments.

 

Full 43×128mm Format Comparison

Stepping Up From the 5,200mAh

Moving from the 5,200mAh to the 6,300mAh in the same 43×128mm bay adds 4.07Wh of stored energy (+21.2%), raises peak burst from 390A to 472A (+82A), and raises continuous from 234A to 284A (+50A) — for 21g of additional weight and 1.7mm of additional thickness. No frame modification is required. For builders who have committed to the 43×128mm format and need every watt-hour and every ampere it can provide, this is the direct upgrade with no compromises.

 

Charging: 2C / 12.6A — Full Charge in ~30 Minutes

The 2C continuous charge rate delivers 12.6A input — the highest absolute charge current in the 43×128mm family — 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 current level the 43×128mm format delivers.

 

Construction: Ceramic Separator and PVDF Electrode

The ceramic separator provides thermal resistance under the extreme discharge conditions of competitive racing at 472A peak and 284A continuous — the simultaneous ceiling of both specifications within the 43×128mm format. The PVDF binder maintains electrode structural integrity through the full 128mm electrode length under the combined stress of maximum sustained and burst discharge across hundreds of high-rate cycles.

 

Ideal Applications

Full-size FPV racing drones requiring maximum sustained current — 284A continuous is the highest sustained output in the entire Ultra Ternary catalog for the most demanding full-size motor configurations.

RC cars with full-size trays requiring above 234A sustained — 45C / 284A continuous in the 43×128mm format, the definitive cell for motor setups exceeding the 5,200mAh’s continuous ceiling.

Large-scale RC aircraft — 23.31Wh at 137g in the 43×128mm bay, maximum energy and current for competitive racing aircraft with larger fuselage compartments.

RC boats requiring above 234A sustained motor output — the highest sustained current available in the 43×128mm format for heavy competitive hull motor configurations.

5,200mAh upgrade builds — same 43×128mm bay, 21.2% more energy, 82A more peak, 50A more continuous, for 21g and 1.7mm, no frame modification needed.

43×128mm definitive build — the absolute endpoint for all 43×128mm platforms before the format steps up to the 70×140mm.

 

Product Summary

The Midlands Power 3.7V Ternary 6,300mAh closes the 43×128mm format at its absolute performance ceiling: 284A continuous — the highest of any Ultra Ternary cell — 472A peak, and 23.31Wh of stored energy, all from a 137g, 10.9mm cell that requires no frame modification from the 5,200mAh. For full-size competitive racing builds fixed to the 43×128mm bay, this is the maximum the format delivers across every specification it measures.
