Choosing the Right Battery for UMX RC Planes
UMX planes operate on compact power systems, which means battery choice directly affects flight stability and safety. A proper UMX battery should be lightweight, provide consistent voltage under load, and match the aircraft’s connector without requiring adapters.
Typical Battery Specs for UMX & Ultra Micro Aircraft
- Voltage: 1S (3.7V), 2S (7.4V), and select 3S setups
- Capacity: 300mAh – 900mAh
- Connector: JST or PH/UMX connectors
- Focus: Low weight, stable discharge, safe thermal behavior
Why CNHL Batteries Work Well for UMX Flying
CNHL LiPo batteries are built with tight cell consistency and controlled discharge curves—important for ultra micro aircraft where even small voltage drops can be felt immediately in flight. These packs are designed to fit cleanly and perform predictably, whether you’re flying indoors or outdoors.

UMX RC Plane Battery FAQ
What type of batteries do UMX planes use?
Most UMX and ultra micro RC planes use small LiPo batteries in the 1S or 2S range. Common capacities are between 150mAh and 850mAh, depending on the aircraft size, motor type, and intended flight style.
Do all UMX planes use the same connector?
No. UMX aircraft commonly use PH/UMX connectors, JST, or IC2 depending on the model. Always match the battery connector to the aircraft to avoid adapters that add weight or cause voltage loss.
Can I use a higher capacity battery in my UMX plane?
You can, but weight matters more than raw capacity on UMX aircraft. Using a battery that is too heavy may shift the center of gravity and negatively affect handling, takeoff, and landing behavior.
Is 2S or 3S safe for UMX planes?
Only if the aircraft is specifically designed for it. Some UMX EDF jets and performance models support 2S or even small 3S packs, while many trainers and park flyers are limited to 1S operation. Always follow the aircraft’s voltage recommendation.
Why does battery choice matter so much on ultra micro planes?
UMX planes operate at very low current levels, so even small voltage drops or added resistance are noticeable in flight. A properly sized battery with stable discharge characteristics helps maintain smooth throttle response and predictable handling.
