How to Choose a 450 Class Heli Battery
Blade length around 325–360mm defines the 450 class. Most pilots pick a pack that keeps AUW modest, head speed consistent, and the tail happy under hard collective. In practice, that means matching voltage and capacity to your blades, motor kV, and flying style.
Voltage & Capacity Tips
- 3S (1500–2200mAh): classic feel on older 450 setups—light, smooth, and friendly for sport flying.
- 4S (1600–2600mAh): a sweet modern baseline: more pop without a big weight penalty.
- 6S (1800–3300mAh): crisp head speed and authority for wind and harder moves—watch AUW to keep disc loading in check.
Browse by voltage: 3S LiPo, 4S LiPo, 6S LiPo.
FAQ

A: Many pilots settle around 4S 1800–2200mAh or 6S 1800–2600mAh—good punch with manageable weight and CG.
Q2: XT30 or XT60 for a 450?
A: Light builds and mild timing can use XT30, but most 450s prefer XT60/EC3 for current headroom under hard collective.
Q3: Is a 450 still a good first “bigger” heli after micro?
A: Yes. 450s are durable, parts are easy to source, and a well-matched RC heli battery keeps the learning curve smooth.
