Best Batteries for Goosky S2 and Goosky S2 Ultra
Both the Goosky S2 and Goosky S2 Ultra are designed around a 3S 11.1V micro helicopter power system with an XT30-style connector, which makes them a perfect match for CNHL MiniStar 3S packs. Instead of experimenting with random drone batteries, you can focus on two proven capacities that work exceptionally well in these helis:
- A lightweight 3S 650mAh pack for agile, precise flying where disc loading and quick stops matter most.
- A higher capacity 3S 850mAh pack when you want more flight time and extra power margin for the Goosky S2 Ultra.
The goal is simple: keep the Goosky S2 platform light enough to stay fun and forgiving, while giving the Goosky S2 Ultra the power and consistency it deserves from a modern micro 3D helicopter.
650mAh vs 850mAh: Which Battery Should You Choose?
Choosing between a 650mAh and an 850mAh battery for your Goosky S2 or Goosky S2 Ultra comes down to how you actually fly. If you spend most of your time flying close-in circuits, simple aerobatics, or working on new maneuvers low to the ground, the lighter 650mAh 3S pack keeps the heli lively and makes bail-outs easier. It changes direction faster, feels less “loaded up,” and lets you develop muscle memory without fighting inertia.
If you already have a solid 3D routine or you simply want more time in the air each flight, the 850mAh 3S option makes sense. The extra capacity can help keep head speed more consistent across the entire flight, especially when you are running higher pitch ranges, harder collective stops, or Rotorflight governors with more aggressive head speeds on the S2 Ultra. The small increase in weight is a fair tradeoff when the model is tuned to handle it.
Can Goosky S2 Ultra Use Larger 3S Packs?
The Goosky S2 Ultra will physically accept slightly larger 3S packs than the original S2, thanks to its carbon side frames and revised layout, but it is still a micro helicopter at heart. Going too heavy on battery capacity can make the heli feel dull and stress the drive system during repeated hard stops and reversals. In practice, most pilots find that staying in the 650–850mAh range on 3S offers the best balance between performance, flight time, and airframe longevity.
If you are coming from generic 750mAh packs, a quality 850mAh battery with a strong 70C rating can actually feel better in the air than a cheaper, lower C pack with a similar label. The key is matching the physical size to the battery tray and keeping the overall flying weight within what the Goosky design was meant to handle.
Why CNHL MiniStar Packs Work So Well on Micro Helicopters
Micro helicopters like the Goosky S2 series place very specific demands on their batteries. Current spikes are short and sharp, tail loads can change rapidly, and modern FBL systems such as Rotorflight expect a pack that does not sag dramatically when the head speed is pushed. CNHL MiniStar 3S packs are built around this kind of usage, with a small footprint, high C rating, and chemistry tuned for repeatable output.
In real flying, that translates into more consistent cyclic feel, fewer moments where the heli “digs in” or falls through during aggressive collective inputs, and a safer margin when practicing new 3D figures. Instead of the battery being the weak link in your Goosky S2 or S2 Ultra setup, it becomes a reliable partner that lets the mechanics and electronics do their job properly.
Goosky S2 vs Goosky S2 Ultra: Battery and Setup Notes
From a battery point of view, the original Goosky S2 and the Goosky S2 Ultra share the same basic requirement: a compact 3S LiPo with an XT30-style connector. Where they differ is how much they can take advantage of a high quality pack. The Ultra adds a stiffer carbon frame, full metal servos, and an advanced Rotorflight-based flight controller, so it can make far better use of the extra punch and stability offered by a premium 3S pack.
If you are running stock settings on a Goosky S2, a 650mAh 3S pack is often the sweetest spot. Once you move to the S2 Ultra and start exploring higher head speeds, more aggressive pitch ranges, or deeper Rotorflight tuning, upgrading to a stronger 650mAh pack or an 850mAh MiniStar battery gives you the electrical margin needed to keep the model locked-in throughout the whole flight.
Recommended CNHL Collections for Micro Heli Pilots
If you fly more than one micro helicopter, or you are building up a small fleet that includes models beyond the Goosky S2 and Goosky S2 Ultra, it makes sense to browse the broader CNHL collections. You can discover other 2S and 3S packs that share similar dimensions and connectors, which helps simplify your charging setup and makes it easier to manage spares.

Goosky S2 / Goosky S2 Ultra Battery FAQ
To make it easier for new and experienced pilots to choose the right pack, here are some quick answers to common battery questions for the Goosky S2 family.
Q: Is the Goosky S2 Ultra a 3S or 4S helicopter?
A: The Goosky S2 Ultra is designed around a 3S 11.1V power system, just like the original Goosky S2. Both models are optimised for compact 3S packs with an XT30-style connector.
Q: Can I use an 850mAh 3S battery in my Goosky S2 or S2 Ultra?
A: Yes, as long as the physical size fits the battery tray and the weight remains reasonable for a micro heli. Many pilots prefer an 850mAh 3S pack on the S2 Ultra for longer flights and a more consistent feel during harder 3D flying.
Q: What connector does the Goosky S2 use?
A: The Goosky S2 series uses an XT30-style connector from the factory. CNHL MiniStar 3S packs with XT30 plugs are therefore a direct fit, which keeps the wiring simple and avoids the need for adapters that can add resistance and clutter.
Q: Where can I learn more about tuning Goosky S2 Ultra with different batteries?
A: For a deeper look at how battery choice interacts with head speed, Rotorflight tuning, and flight style on the Goosky S2 Ultra, you can refer to our detailed guide in the blog section:
