As Li-Ion cells have higher energy density than LiPo (more capacity mAh at the same weight), they make great battery for long range flying, in this post I will show you how I built a 4S 18650 Li-Ion battery.
As Li-Ion cells have higher energy density than LiPo (more capacity mAh at the same weight), they make great battery for long range flying, in this post I will show you how I built a 4S 18650 Li-Ion battery.
In this post I will test various 18650 Li-Ion batteries and decide which one is the best 18650 battery for low current application. For example, powering equipment in drone racing and FPV, such as your FPV Goggles and radio transmitters.
