Lithium batteries

Internal resistance (IR) is a characteristics of a battery cell that is often overlooked. It is in fact one of the most important.
Why is it important? What is the impact of having cells with different internal resistance?
I will cover a bit of theory and translate the research results into practical impact…

Learn about the optimal conditions and a few simple precautions to keep your lithium battery healthy for a long life.

This article explains in simple terms how a lithium battery functions, the factors that contribute to it’s premature aging and the steps to maximize it’s life expectancy.

Lithium batteries are the standard for Electric Vehicles and portable equi pment where charge and discharge currents are important compared to the battery capacity. But for an off-grid application is the extra cost justified? What are their benefits and disadvantages when currents are much lower and performance over a long period of time is more important?
