Power Tool Batteries as Real-World Distributed Systems: Failure, Balancing, and Optimization

Power tool batteries are rarely discussed in software or systems engineering. But they should be. Because a modern lithium battery pack behaves very much like a distributed system under load . 1. Cells = Nodes in a Distributed Network Each cell: Has its own voltage Its own internal resistance Its own degradation curve Yet they must operate as a single unit. This creates classic distributed system problems: Imbalance Synchronization issues Failure propagation 2. The Weakest Node Problem In a batt
