- Minimize OEM component disruption
- Use OEM mounting points
- Can be installed on a separate drive system to avoid affecting the the OEM system (For example, we can create a split system operating at 12 and 24 volts to provide current at the appropriate voltage.)
- Include complete installation instructions
- More power at idle: APS can include a high idle switch or vehicle PCM flash as part of the dual alternator kit.
- Custom battery trays: Add one or two batteries in the vehicle engine bay to accommodate a 12- or 24-volt battery bank. APS can size the battery bank appropriately to meet unique requirements, such as those for silent watch or on-site work (no access to shore power).
- Better batteries: APS recommends high-quality AGM, or lithium-ion battery solutions, when developing configurations.
- Additional power components and accessories: APS also provides components including DC to DC converters, smart alternator regulators and battery isolators to ensure dependable power to all vehicle equipment and systems.
