Using 18650 Li-ion Cells Instead of LiPo Batteries in RC Planes

on

Question: Can I use Li-ion 18650 cells instead of LiPo in an RC plane?

Answer: While 18650 Li-ion cells can technically power an RC plane, they are not an ideal substitute for LiPo batteries. LiPo packs provide high current output and a lightweight, compact design tailored for RC use. 18650 cells typically have lower discharge rates and are heavier, which can reduce flight performance and increase weight.

If you want to try 18650 cells, follow these steps:

  1. Use high-quality, protected 18650 cells rated for continuous discharge above 10-15A.
  2. Arrange enough cells in series and parallel to match the voltage and capacity of your original LiPo pack.
  3. Include a proper battery management system (BMS) to balance cells and protect against overcharge, over-discharge, and short circuits.
  4. Ensure the battery holder is secure and vibration-resistant in the plane.
  5. Test the setup on the ground to check for voltage sag and heat generation under load.

Keep in mind, LiPo batteries remain the preferred choice for most RC planes due to their superior power-to-weight ratio and discharge capabilities.
