I'm curious about Dewalt tools and their battery systems. I understand that the tools themselves have a total voltage cutoff at around 15V, but I'm wondering if there's any monitoring for individual cells that prevents them from dropping too low, like below 2.5V, even if the total pack voltage is still within limits. Can anyone clarify how this works?

Great question! For most standard Dewalt 18V tools, the voltage cutoff is managed at the tool level without individual cell monitoring. This means that if the total voltage drops below 15V, the tool will stop working. However, for the C3 (10.8V) batteries, they do monitor the cells more closely, shutting down when certain thresholds are met. On the other hand, Flexvolt batteries are a bit different; they actually monitor each cell and will stop the tool if any cell drops below 3V. So, it's a mixed bag depending on the battery type!
Thanks for breaking that down! Do you happen to know if Dewalt has any official documentation on the C3 monitoring?
