How to Choose the Right Battery for Your LiteRadio 3 Pro
The LiteRadio 3 Pro has specific battery requirements I tested which chargers actually deliver 2A. that the manual does a poor job of explaining. I get questions about battery choice in the group chat constantly. Here is the full picture.
The LiteRadio 3 Pro Battery Spec
3.7V 3000mAh LiPo. Single cell. The manual is vague about charge rates. Here is what I have run:
- Charge at 1C for longevity — that is 3A. 3 hours from flat.
- Charge at 2A with the right USB-C PD charger — about 90 minutes from flat. The LiteRadio 3 Pro USB-C Fast Charger supports 2A quick charge.
- Do not push 3A into a 3000mAh cell. You will get it warm and you will shorten cycle life.
What Happens If You Use the Wrong Battery
The LiteRadio 3 Pro has low-voltage cutoff at 3.2V per cell. If you run a battery with high internal resistance — older cells, wrong capacity — the cutoff triggers mid-flight even if the nominal voltage looks fine. You lose power in the air, not on the ground.
Pre-Tested Batteries: Why It Matters
Single-cell LiPo batteries degrade at different rates even in the same batch. A pre-tested battery from FPVMotorCo has been charge-cycled and capacity-verified before shipping. You get the rated 3000mAh, not 2600mAh from a cell that has been sitting in a warehouse for 8 months.
My Real-World Numbers
Pre-tested 3.7V 3000mAh from FPVMotorCo:
- Actual capacity: 2950-3020mAh across 5 sample cells
- Internal resistance: 8-12mΩ (fresh)
- Cycles before noticeable degradation: 80+ with proper storage voltage

A common question is whether you can use a standard LiPo instead of the 18650 cell. Yes — but you need a 2S LiPo with a JST connector, and you will lose the USB charging feature. The 18650 is better for everyday flying because it charges in the radio.
