Davydd-although it is A CS it is not the same situation. the guy on the sprinter page had the mini-e-trek package already installed.
thats 4 batteries/engine generator/2500 watt inverter/charger/. he tried adding 4 six volt batteries to it (not using same size batteries) to make it a full e-trek(although 2500 watt inverternot full e-trek 5000). his system not wired correctly for this.
Steve has the standard CS. 1250 watt inverter but no engine generator-i assume he as Onan(you can get 4 total batteries from roadtrek with no generator at all) 2 additional batteries will be just that-2 additional batteries.
