In this video we’ll show you an overview of the process for installing a Nations high output secondary alternator and Wakespeed WS500 regulator in a Ram Promaster (Similar process for Mercedes Sprinter and Ford Transit).
This van was built out a few years prior but the owner wanted to be able to recharge his batteries quicker than standard combination of vehicle alternator charging with a DC-DC charger and solar. Because his van used Battleborn batteries, which are approved by Wakespeed the upgrade was fairly simply from an electrical point of view. Battleborn is one of the very few internal BMS (“legacy”) batteries that are officially supported by the Wakespeed regulator. Learn more about the Wakespeed and why some battery brands are approved in our deep dive with the creator of the Wakespeed.
You’ll see how the secondary alternator addition becomes the most powerful of 4x charging sources in this van (solar, shore power, vehicle alternator, secondary alternator) making it a worthwhile upgrade for those that like to be off grid while staying comfortable! This is especially true for vanlifers who are looking to install a 12v, 24v or 48v air conditioner in the camper van.
