Built for long-range FPV, RC aircraft, RC cars, and RC boats, where maximum flight or run time is the primary objective.

 

Key Specifications at a Glance

 

Why Choose the Midlands Power 10,000mAh HV LCO Ultra Battery?

Highest Stored Energy of Any Ultra Cell — 38.50Wh

At 38.50Wh, this is the most energy-dense cell in the entire Midlands Power Ultra range. The nearest competitor in the HV LCO tier — the 3.8V 8,000mAh — stores 30.40Wh, making this cell 8.10Wh (26.6%) more capable for extended-range missions. For long-range FPV pilots and RC racers where battery capacity directly determines flight time and range, this is the definitive choice.

 

248 Wh/kg — Best Gravimetric Energy Density in the Ultra Lineup

The 4.45V high-voltage charge platform and optimized HV LCO electrode architecture combine to deliver 248 Wh/kg — the highest of any Ultra cell across all chemistries and form factors. Compared to 3.7V Ternary alternatives, this cell delivers:

• 46% more energy per gram than the 3.7V Ternary 6,300mAh (170 Wh/kg)
• 48.5% more energy per gram than the 3.7V Ternary 8,000mAh (167 Wh/kg)

 

3.85V Nominal — Highest Voltage in the Entire Midlands Power Catalog

The 3.85V nominal platform is the highest per-cell voltage across all 48 products in the Midlands Power range — Volt, Prime, Max, and Ultra series combined. For motor controllers and power systems tuned to the elevated HV LCO discharge curve, the 3.85V platform delivers higher system efficiency and pack voltage than any 3.8V or 3.7V alternative.

 

350A Peak Burst — Highest HV LCO Peak Current in the Ultra Range

World-leading stacking technique enables 350A instantaneous peak current at 35C — 70A more than the 3.8V HV LCO 8,000mAh’s 280A. For takeoff loads, throttle punches, and peak motor demands on long-range FPV platforms, this cell provides the highest HV LCO burst output available.

 

9.4mm Thin — More Capacity in a Slimmer Profile

Despite carrying 2,000mAh more than the 3.8V HV LCO 8,000mAh, this cell is 1.4mm thinner (9.4mm vs. 10.8mm). The wider 60×120mm footprint distributes electrode material across a greater surface area, enabling thinner stacking at higher capacity — a direct advantage for builds where bay depth is limited.

 

Continuous Discharge: Understanding the 15C / 150A Rating

The 15C continuous discharge rating (150A) is intentionally optimized for long-range efficiency rather than sustained burst performance. This is the design trade-off that enables 248 Wh/kg — the electrode architecture prioritizes maximum energy storage at the 4.45V platform over the higher continuous C-ratings of the Ternary cells (45C–60C) or the 3.8V HV LCO 8,000mAh (20C/160A).

This cell is the right choice when: sustained motor load throughout cruise and racing phases stays within 150A, and maximum stored energy at minimum weight is the build priority.

For sustained loads above 160A, the 3.8V HV LCO 8,000mAh (20C/160A) is the recommended alternative.

Charging: 2C / 20A — Full Charge in ~30 Minutes

The 2C continuous charge rate delivers a clean 20.0A input, fully charging the cell in approximately 30 minutes. Running multiple cells in rotation at 2C supports continuous long-range operations at the maximum energy level available in the Ultra HV LCO range.

 

Ideal Applications

Long-range FPV drones — 38.50Wh at 248 Wh/kg is the highest available energy-per-gram combination in the Ultra lineup, directly extending maximum flight time and range.

Extended-range RC aircraft — 3.85V at 155g in the 60×120mm format maximizes energy for competitive and recreational distance flying.

RC cars (maximum distance/efficiency events) — 38.50Wh at 150A continuous provides the longest sustained run time of any Ultra cell.

RC boats (long-duration hull motor applications) — 350A peak and 150A continuous from the HV LCO 3.85V platform, with the highest stored energy in the lineup.

Voltage-sensitive long-range systems — 3.85V nominal is the highest per-cell voltage available across the entire Midlands Power catalog.

 

Construction: World-Leading Stacking Technique at 4.45V

Precise internal electrode layer alignment across the full 60×120mm footprint is critical at the 4.45V high-voltage charge ceiling — the highest operating voltage in the Ultra lineup. World-leading stacking technique ensures consistent energy density realization, prevents internal short-circuit risk under elevated electrochemical stress, and maintains reliable, stable discharge throughout the long-range profile.

 

Product Summary

The Midlands Power 3.85V HV LCO 10,000mAh is the final cell in a 48-product catalog spanning four series, 11 voltage platforms, and 21 distinct form factors. It closes the catalog with three absolute performance records within the Ultra lineup: highest stored energy (38.50Wh), highest gravimetric energy density (248 Wh/kg), and highest nominal voltage (3.85V). For long-range FPV and RC platforms where these three specifications define the build, this is the definitive answer the Ultra lineup provides.
