New "Quality Fundamentals for Battery Energy Storage Systems (BESS)" course just launched! Check it out!
I strongly suggest this course to those who want to gain learning, and improve their skills.
I've liked Heatspring's prior courses, but this seemed like it was just put together real quick from content that was already out there. My expectations were to learn about batteries, yet there was so much solar content that I've already studied in this same platform.
