When building a lithium-ion battery pack, there will always be some sort of protection circuitry necessary that will safely separate the cells from the external connections. The protection may be as simple as a pair of charge and discharge Field Effect Transistors (FETs) with voltage and current detectors, or as complicated as adding firmware controlled fuel gauging and secondary protection.

Proper Battery Pack and Battery Pack Charger Matching

Written by Anton Beck
Posted on May 1, 2015 at 10:48 AM

In today's battery and charger market, most companies typically provide either battery pack assemblies or battery pack chargers, as opposed to providing both. In the past, buying a battery from one source and a charger from another worked just fine when using the older NiCd batteries with overnight chargers. However, due to new battery chemistries and the increasing need for faster charge times, careful matching of the charger to the battery has become essential. Without proper battery and charger matching, aspects such as safety, cycle life, and run-time may be greatly affected.
