Tenergy 9.6V 1600mAh NiMH Butterfly Battery Pack — 2-Pack with Mini Hobby Plug, Split-stick for Tight Spaces

If your project, transmitter, or small vehicle needs a dependable, rechargeable power source that fits into narrow compartments, this two-pack delivers consistent output and easy installation. The twin-stick "butterfly" layout places two slim cells side-by-side on flexible leads so you can route power into tight bays or dual compartments where a single block battery won't fit. Pre-wired with a standard mini hobby connector, these packs make swaps and replacements fast for hobbyists who want balance between runtime and compact sizing.

How does the butterfly layout help in cramped battery bays?

The split-stick configuration separates the battery into two slim cells connected by flexible wiring, letting you position each stick independently inside irregular housings. This reduces installation stress and avoids forcing or modifying the device enclosure.

• Two narrow cells each 4.65 x 0.70 inches for easy routing
• Flexible lead wires let you bend sticks into corners or separate compartments
• Fits devices that can't accept a single rectangular pack

What kind of performance and charging behavior can I expect?

Each pack uses NiMH chemistry, chosen for predictable discharge and tolerance of repeated recharge cycles. With 1600mAh capacity at 9.6 volts, these packs offer moderate runtime for radios, small vehicles, or custom hobby builds and accept standard NiMH charging methods.

• 1600mAh capacity delivers sustained power for extended sessions
• NiMH chemistry is rechargeable and resists memory issues with proper cycling
• Compatible with common NiMH/NiCd hobby chargers using the mini plug

Is the connector and wiring suitable for hobby use?

The packs come pre-terminated with a standard mini hobby plug and flexible leads, enabling immediate drop-in replacement with most transmitters and receivers that use the mini-style connector. The wiring is designed for reliable current flow while allowing room to maneuver during installation.

• Standard mini hobby connector for wide compatibility
• Pre-wired leads reduce assembly time and wiring mistakes
• Robust connection suitable for vibration-prone models

How compact are these packs compared to single-block batteries?

Rather than one bulky rectangular block, the twin-stick design significantly reduces the cross-sectional thickness, enabling a lower profile fit. That compact footprint makes it easier to preserve internal layout and airflow inside smaller housings.

• Each stick measures 118 x 18 mm for narrow-bay compatibility
• Lower profile allows use in slimmer transmitters and narrow chassis
• Two-pack gives you spare power or simultaneous use in multiple devices

Who is this for? Hobbyists, RC enthusiasts, and makers who need a rechargeable power source that fits nonstandard battery cavities will appreciate these Tenergy packs. They suit radio transmitters, small-scale vehicles, battery trays with split compartments, and DIY electronics that require a reliable mini-plug connection and compact form factor. If your project values a balance of capacity, rechargeability, and flexible installation, this 2-pack offers convenient power with commonly used NiMH compatibility.
