Which Battery Chemistry is Best: A Comprehensive Comparison

While batteries are nothing new, advancements and the race for the “best battery chemistry” is as ferocious as ever. While the competition is intriguing, it might operate on a flawed premise. 


What if there didn’t have to be a winner-take-all end to this race? What if specific battery chemistries excel in some areas and are poor in others?

Choosing the Right Solar Charge Controller: How to Optimize Your System and Increase Efficiency

A complete solar solution includes a panel, a storage device, a battery, and a charge controller to manage the power generated by the panel and stored in the battery. 


At its most basic level, a charge controller maintains your battery’s health and ensures you aren't damaging it. Charge controllers work in several ways to regulate the voltage sent to the battery, and you can throw away enormous amounts of energy if paired with an inappropriate or inefficient controller.
