Custom battery packs for your OEM project.
Build the specification around what the battery needs to do: the load, the installation, the interfaces and the operating environment.

More than a choice of enclosure.
evjrich provides battery customization for project requirements. Start by defining the electrical and physical constraints, then discuss the battery configuration and the route from evaluation to supply.
- Voltage, energy and charge/discharge requirements
- Enclosure, mounting and connector arrangement
- Battery management and communication needs
- Application, environment and evaluation requirements
Build the project step by step.
Application brief
