Question Need advice from someone with knowledge on either 30A or 15A power systems

[CIK7]

I am doing a custom recreational (legally 'utility') conversion on a 1998 Volvo V70 wagon. Here is my dedicated thread for that. I just need to know what all I need for the power system and how to make it work.

Whether I build a basic 15/20A charging system or an upgraded 30A (PREFERRED) type, I need input on what all I need to make it happen. I plan to have 2 large special batteries (no battery format, chemical type, or numericals here for sake of teasers). I want to use an AC to DC converter. I thought if I used a 55A version like this then I should be able to successfully either hook up a 30A or 15/20A receptacle.

So yeah, fill me in. Let me know what all I need to look at.

The provided charger is only a 20amp charger. You can connect to 50,30, or 20 amp but will only use 20.

What other electric devices using AC power will you have on your conversion? That will determine the need.
