Description

The ceiling of the 20×122mm format — 30% more energy, 30% more peak current, and 30% more continuous output than the 1,000mAh for just 5g and 1.0mm more. The 3.7V Ternary 1,300mAh delivers 143A peak and 78A continuous from a 27g, 6.0mm soft pack in the 20×122mm footprint — the maximum capacity, maximum energy, and maximum current the 20×122mm format delivers. Built for FPV racing drones, RC aircraft, RC cars, and RC boats where the narrow 20mm width is the fixed constraint and maximum performance in the 20×122mm bay is the objective.

 

Key Specifications at a Glance

Why Choose the Midlands Power 1,300mAh Ultra Ternary Battery?

30% More Energy and Current Than the 1,000mAh — For Just 5g and 1.0mm

Stepping from the 20×122mm 1,000mAh to the 1,300mAh delivers a clean and consistent +30% gain across every performance specification simultaneously — for the smallest possible physical addition in the same bay:

For any build currently running the 20×122mm 1,000mAh where more current or run time is needed, the 1,300mAh is a direct, no-modification upgrade delivering the maximum the format can provide.

 

143A Peak — The Maximum Burst Current in the 20×122mm Format

Advanced electrode material formulation delivers 143A of instantaneous peak burst current at 110C — the absolute maximum peak output available in the 20×122mm footprint. There is no higher peak current in this bay. For motor and ESC configurations that push toward the current ceiling of the 20×122mm format during peak demand events — launch acceleration, rapid throttle transitions, instantaneous load spikes — the 1,300mAh is the only cell in this footprint that provides it.

 

78A Continuous — The Maximum Sustained Output in the 20×122mm Format

At 60C continuous from 1,300mAh, this cell delivers 78A of sustained output — the highest continuous current available in the 20×122mm format, and 18A more than the 1,000mAh’s 60A. For racing runs where sustained motor loads approach or hold near the continuous ceiling, the additional 18A headroom reduces the likelihood of hitting continuous current limits during aggressive sustained throttle inputs throughout the full discharge.

 

The Ceiling of the 20×122mm Format — No Higher Capacity in This Bay

The 1,300mAh is the highest capacity available in the 20×122mm footprint. There is no higher capacity, no higher peak current, and no higher continuous output in this bay. Moving above 1,300mAh requires a different format entirely — the 30×48mm (different width and length) or the 34×62mm (wider and shorter). For builders committed to the 20×122mm bay geometry by frame design, mounting constraints, or width requirement, the 1,300mAh is the definitive and only endpoint.

 

6g Lighter and 1.1mm Thinner Than the 34×62mm 1,300mAh — Same Energy

The 20×122mm and 34×62mm formats both offer a 1,300mAh cell storing 4.81Wh at the same 60C/78A continuous rating. The difference is geometry and peak rate:

For builds where the 20mm width is the required dimension and 6g or 1.1mm of thickness matters, the 20×122mm is the correct cell. For builds where width is flexible and the 26A additional peak burst of the 34×62mm is the priority, the 34×62mm is the appropriate choice. The decision is bay geometry — not a performance hierarchy.

 

Ceramic Separator and PVDF Electrode — Racing-Grade Construction

Industry-first ceramic separator and PVDF electrode construction deliver thermal resistance and structural integrity at the demanding output levels of competitive racing. The ceramic separator reduces thermal runaway risk under the sustained 78A continuous load. The PVDF binder maintains electrode structural integrity throughout the full 122mm cell length under the mechanical stress of high-rate cycling, contributing to long cycle life and consistent performance across hundreds of charge-discharge cycles in demanding racing environments.

 

Full 20×122mm Format Comparison

Same Capacity — 1,300mAh Across Formats

Stepping Up From the 1,000mAh

Moving from the 1,000mAh to the 1,300mAh in the same 20×122mm bay adds 1.11Wh of stored energy (+30%), raises peak burst from 110A to 143A (+33A), and raises continuous from 60A to 78A (+18A) — for just 5g of additional weight and 1.0mm of additional thickness. No frame modification is required. This is the only capacity step available in the 20×122mm format, and it closes the bay at its absolute performance ceiling.

 

Charging: 2C / 2.6A — Full Charge in ~30 Minutes

The 2C continuous charge rate delivers 2.6A input — the highest absolute charge current in the 20×122mm format — 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 level the 20×122mm format delivers without interruption.

 

Ideal Applications

FPV racing drones with narrow long bays — maximum 143A peak in the 20×122mm format, the ceiling of what this narrow long bay delivers.

RC aircraft with elongated fuselage or wing channels — 20×122mm length at 6.0mm suits elongated routing where wider cells do not fit.

RC cars with long shallow narrow trays — 143A peak in a 27g, 6.0mm cell, maximum rate for long narrow shallow battery trays.

RC boats with thin narrow hull compartments — 60C / 78A continuous in the lightest, narrowest 1,300mAh format available.

Gun models requiring maximum narrow-format energy — the highest energy in the 20×122mm form factor for the longest run time in narrow battery cavities.

20×122mm 1,000mAh upgrade builds — same bay, 30% more energy and current, for just 5g and 1.0mm, no frame modification required.

 

Product Summary

The Midlands Power 3.7V Ternary 1,300mAh closes the 20×122mm format at its absolute performance ceiling: 143A peak — the maximum the format produces — 78A continuous, and 4.81Wh of stored energy in a 27g, 6.0mm cell, 6g lighter and 1.1mm thinner than the 34×62mm 1,300mAh at the same energy. For competitive racing builds fixed to the 20×122mm bay where the 1,000mAh is insufficient, there is nothing above this cell in the format.
