Charge Confusion...

Stay Frosty

Bearing in mind I bought my camper ready made it has a Sargent EC160 panel fitted to allow for charging the onboard leisure battery in tandem with a small consumers unit for 230v power.

Thinking about it for the first time today am I right that this device will only allow for charging of the leisure battery or vehicle battery when the vans hook up cable is fed from the camp site supply and not when driving?

The painful thinking part was brought about when grappling with the dubious concept of the "smart" alternator not always providing an high enough DC voltage to charge the vehicle battery fully and logically the leisure battery.

The van has been converted by Redline and the dual passenger seat is on a swivel so no bundle of wires there and the leisure battery is installed beneath the drivers seat with the two battery leads and what I guess is an airbag pair being the only wiring under there.

Being a novice I'm wondering if a DC to DC charger could or should be introduced before the Sargent panel to blast some electric into the leisure battery while driving around?
 
I have the Sargent EC328 which was useless for charging when driving so we now have a Sterling battery to battery charger installed and we have disabled the Sargent split charger.

I'm not sure the dc160 charges both battery's when on EHU. I've got the vechicle dab with speakers around the back. A bit concerned it will drain the vechicle battery if not charging?
 
It's generally best to have an independent audio system off the leisure or a Bluetooth speaker for camping.

Using the vehicle head unit it's not just the power of the head unit itself but the fact you will generally have the ignition on and everything else powered up.

Additionally if you enjoy a drink having the keys in the ignition can lead to some issues it's easiest to avoid.
