Hi Chris
How they set up the wiring and programming. I am a field engineer for Jeep uk and have not seen this conversion so would very much like to know more about it. I have the dealer diagnostic tool, the jeep engineering tool and jeep bus logger.

Where are you located in the UK? do you have more information on the conversion? interested in the wiring side only for the bus/ engine ECU. Would have to wait till after lock down but would be interesting see this conversion and I could help you resolve this.

My test was on a jeep renegade 1.4 but you can see I selected 500 sae battery. This vehicle has stop start function and a smart alternator that maybe a factor?

interesting I did my first ever battery test today and also got the same reading
