Solar Batteries: Lead-Acid vs Lithium is a clear, practical, and technical guide for anyone building a solar power system at home, off-grid, or for backup power. This book breaks down the real-world differences between lead-acid and lithium batteries, explaining how each chemistry performs, charges, ages, and responds under load.

Written in straightforward language with engineer-level depth, it covers charge algorithms, cycle life, Peukert's Law, voltage sag, discharge curves, system sizing, maintenance, safety, and long-term cost analysis. Whether you're designing an off-grid cabin, upgrading to lithium batteries, or simply want to understand the science behind solar storage, this book gives you the knowledge to choose the right battery and build a reliable, long-lasting solar energy system.
