When Does Equipment Need a Custom Battery Configuration?
A high voltage lithium ion battery pack uses a series-parallel arrangement of lithium-ion cells to deliver the voltage, energy and current required by a particular electrical system.
The term high voltage does not describe one universal battery rating. Its technical meaning depends on the application and applicable standards.
Unlike a standard voltage-specific product, a high-voltage lithium-ion battery pack may require an application-specific combination of cell configuration, protection, charging and installation interfaces.
Operating Voltage and Battery Chemistry
Battery selection begins with the minimum and maximum voltages accepted by the equipment. Cell chemistry and series count determine the pack’s nominal voltage, full-charge voltage and allowable discharge limits. They also influence the charger and BMS requirements.
Two batteries described by similar voltage classes may not be electrically interchangeable.
When Standard Packs Are Not Suitable
A custom configuration may be considered when:
The equipment requires an operating voltage range not met by available standard packs.
Energy capacity and discharge current must fit within restricted dimensions.
The battery needs a specific charging or monitoring interface.
Standard enclosures or connections cannot accommodate the equipment’s installation requirements.
The application has particular environmental or electrical protection requirements.
These conditions should be established before the cell arrangement and pack structure are finalized.
