By connecting two or more batteries in either series, series-parallel, or parallel, you can increase the voltage or amp-hour capacity, or even both; allowing for higher voltage or power hungry applications.
The battery is made up of cells, each cell consists of plates immersed in an electrolyte of dilute sulfuric acid.
The selection of a suitable SLA battery charger and the methods used to charge it is just as important as choosing the right battery for the application.
For the purpose of this white paper, lithium refers to Lithium Iron Phosphate (LiFePO4) batteries only, and SLA refers to lead acid/sealed lead acid batteries.
As you will learn in this white paper, there are many similarities in the charging profiles of SLA and lithium.
In a battery with a balancing chip, the chip simply balances the voltages of the individual cells in the battery while it is charging.
