We have a 2021 Mercedes Sprinter and are installing two Orion TR Smart DC-DC Charger Non-Isolated in Parallel to give us more charge capacity from the van's alternator. I've read several post about how to install these devices but it is still unclear what is the proper way to connect the chargers to the van.
Is it best to connect directly to the alternator, the starter battery, or the fuse location under the drivers seat? Of course, all of these scenarios would be fused. The best information I've found is here: https://www.youtube.com/watch?v=01F4QDVJUq0&t=3163s but this is for a singe charger.
