In Part 2 of this series we took a look at how LiPo cells behave electrically over a discharge cycle. There were a few observations (like voltage sag) that can’t be explained by applying Ohm’s Law directly. Internal resistance is a metric that aims to explain some of these properties. Why is Internal Resistance Important? Read more about LiPo Characteristics Part 3: Internal Resistance[…]

In the previous post of the series, I outlined some basic information about this study. In this post, I’ll start diving in to the data to see what it tells us about LiPo characteristics. I’d recommend you give part 1 a read to familiarize yourself with the method I used to collect data. A word Read more about LiPo Characteristics Part 2: Electrical Properties[…]

Introduction Recently, I became curious about LiPo characteristics and quirks. What causes the drop-off in responsiveness over time? Why does power seem to fall off a cliff at the end of capacity? Why do throttle punch outs cause my flight controller to brown out when the battery is low? What makes one battery better than Read more about LiPo Characteristics Part 1: Introduction[…]
