Putting Batteries in Parallel? Better Watch Out for These Failure Modes

JD DiGiacmandrea, Green Cubes

As the demand for increased energy storage capacity grows, engineers are frequently challenged to place multiple batteries in parallel. Using multiple batteries can offer extended runtime, enhanced reliability, and the ability to carry energy to different locations that may not have charging capabilities. With th
