Recommended CNHL Batteries for the FMS & Arrows Hobby Viper 30mm
The Viper 30mm is a lightweight micro EDF, so the best battery is not simply the largest 2S pack that can fit inside the fuselage. Keeping the battery compact helps preserve the quick acceleration, responsive handling and easy hand-launch characteristics that make this aircraft enjoyable to fly.
CNHL offers three MiniStar batteries that suit this platform particularly well, covering both the original 450mAh capacity direction and a practical 550mAh upgrade.
CNHL MiniStar 450mAh 7.4V 2S 70C LiPo — Best Stock-Style Choice
CNHL MiniStar 450mAh 7.4V 2S 70C LiPo Battery with XT30U is the most natural starting point for the Viper 30mm because its 450mAh capacity closely follows the original battery setup.
At approximately 65 × 18 × 16mm and 35g, it keeps the battery package small and light while delivering the standard 2S voltage used by the aircraft. This is the easiest choice for pilots looking for straightforward spare batteries without changing the basic capacity of the original setup.
CNHL MiniStar HV 450mAh 7.6V 2S 70C — Lightweight LiHV Choice
3 Packs CNHL LiHV MiniStar HV 450mAh 7.6V 2S 70C Battery with XT30U keeps the same 450mAh capacity while moving to LiHV chemistry.
Each pack measures approximately 64 × 19 × 15mm and weighs about 32g, making it the lightest of the three recommended options. The 7.6V LiHV design can be charged to 8.7V fully charged and is a strong option for pilots who want to stay with the original 450mAh capacity while using a compact high-voltage pack.
The three-pack format also suits a small EDF particularly well, allowing several flights to be prepared without moving to a much larger single battery.
CNHL MiniStar HV 550mAh 7.6V 2S 70C — Higher-Capacity Choice
3 Packs CNHL LiHV MiniStar HV 550mAh 7.6V 2S 70C Battery with XT30U increases capacity to 550mAh while remaining remarkably compact.
Each pack measures approximately 66.5 × 16.5 × 15.5mm and weighs about 35g. That means it carries 100mAh more capacity than the 450mAh options while remaining in essentially the same lightweight battery class.
For Viper 30mm pilots who want more energy per pack without jumping to a bulky battery, the 550mAh LiHV is the most attractive capacity upgrade in this collection.
| Battery | Capacity | Voltage | Dimensions | Weight | Best For |
|---|---|---|---|---|---|
| MiniStar 450mAh LiPo | 450mAh | 7.4V 2S | 65 × 18 × 16mm | Approx. 35g | Closest to original capacity |
| MiniStar HV 450mAh | 450mAh | 7.6V 2S LiHV | 64 × 19 × 15mm | Approx. 32g | Lightweight LiHV setup |
| MiniStar HV 550mAh | 550mAh | 7.6V 2S LiHV | 66.5 × 16.5 × 15.5mm | Approx. 35g | More capacity with similar pack weight |
450mAh vs 550mAh for the Viper 30mm
450mAh remains the best all-around starting capacity for the Viper 30mm because it follows the original battery specification closely. It keeps the aircraft light and leaves plenty of room inside the compact battery compartment.
The 550mAh LiHV pack is more interesting than a typical capacity upgrade because its approximate 35g weight is still very close to the standard 450mAh LiPo. In other words, pilots can gain additional capacity without moving to a dramatically heavier battery.
Choose 450mAh for the closest stock-style setup.
Choose 550mAh when additional capacity is more important.
Choose LiHV when you want the 7.6V high-voltage MiniStar option.
Why Small, Lightweight Batteries Work Best in the Viper 30mm
The FMS and Arrows Hobby Viper is a true micro EDF, with a wingspan of approximately 460mm, a length of about 410mm and a flying weight around 120g. At this size, keeping the battery compact helps the aircraft retain the quick and lively character expected from a small sport jet.
A very large battery may technically offer more capacity, but it would also take up more room and add unnecessary mass. The MiniStar 450mAh and 550mAh packs stay within a narrow size and weight range, which makes them much better suited to this lightweight airframe.
The small battery size also makes carrying several packs easy. Instead of relying on one oversized battery, pilots can bring multiple 450mAh or 550mAh packs and swap them quickly between flights.
2S LiPo and LiHV Options for the Viper 30mm
The Viper 30mm is designed around a 2S power system, and both standard LiPo and LiHV batteries work well in this setup.
A standard 2S LiPo has a nominal voltage of 7.4V and reaches 8.4V when fully charged. A 2S LiHV pack has a nominal voltage of 7.6V and reaches 8.7V when fully charged in LiHV mode.
The standard MiniStar 450mAh LiPo is ideal for pilots who prefer the conventional 2S setup, while the MiniStar HV 450mAh and 550mAh batteries provide compact LiHV alternatives for the Viper 30mm.
Compact Batteries for a Fast Micro EDF
One of the most interesting things about the Viper 30mm is that its size can be deceptive. The aircraft is extremely easy to transport and store, yet it still delivers the speed and energy of a small EDF jet rather than the slow flying style of a typical micro trainer.
That makes lightweight batteries especially useful. A compact pack allows the aircraft to accelerate quickly after launch, carry speed smoothly through turns and retain the agile handling expected from a small Viper-style sport jet.
The 450mAh and 550mAh MiniStar batteries keep the complete power package small enough to match the character of the aircraft instead of turning a very light micro jet into an unnecessarily heavy setup.
XT30U Batteries for the Arrows Hobby Viper 30mm
All three CNHL batteries featured in this collection use XT30U connectors. The compact XT30 format is well suited to lightweight aircraft because it provides a secure brushless power connection without the size and weight of larger RC connectors.
This also makes the selected MiniStar series a practical choice for pilots who want several matching spare batteries for repeated flights with the Viper 30mm.
FMS & Arrows Hobby Viper 30mm Battery FAQ
What battery does the Arrows Hobby Viper 30mm use?
The original battery direction is 2S 450mAh. A compact 450mAh 2S pack is therefore the best starting point for replacement and spare batteries.
Can I use a 550mAh battery in the Viper 30mm?
Yes. The CNHL MiniStar HV 550mAh 2S pack is a suitable higher-capacity option and remains close in size and weight to the recommended 450mAh batteries.
Can the Arrows Hobby Viper 30mm use LiHV batteries?
Yes. The Viper 30mm can use compact 2S LiHV batteries such as the CNHL MiniStar HV 450mAh and 550mAh options featured in this collection.
Is 450mAh or 550mAh better for the Viper 30mm?
450mAh is the best choice for staying close to the original battery capacity. The 550mAh LiHV pack is better for pilots who want additional capacity while keeping the battery compact and lightweight.
What connector do these Viper 30mm batteries use?
The three CNHL batteries selected for this collection use XT30U connectors.
How many spare batteries should I carry?
Micro EDF batteries are small and easy to transport, so carrying several 450mAh or 550mAh packs is a practical way to enjoy multiple flights without waiting for a battery to recharge at the field.
More Batteries for Micro EDF and RC Airplanes
The FMS and Arrows Hobby Viper 30mm shows how much EDF performance can now fit into a very small airframe. Its compact 2S power system also makes battery preparation simple: several lightweight packs can easily be carried to the field, allowing pilots to spend more time flying and less time waiting for a single battery to recharge.
For the Viper itself, the choice is straightforward. The 450mAh 7.4V MiniStar stays closest to the original setup, the 450mAh MiniStar HV provides a lighter high-voltage alternative, and the 550mAh MiniStar HV adds useful capacity while remaining in the same compact battery class.
