When i first tested it in my Caravan, I tried to test it on my 3xway fridge whilst on 12 volt setting as it would be when I'm in transit. My old AGM 120 Amp Hr would only hold the Fridge for about 8-10 Mins at 12.4 Volts at the end. When I tested the new Lithium form Itechworld, I thought initially that it was not working at all, as in the first 20 mins in test phase, it didnt drop .1 of a volt. After 1.5 Hrs of test time, without any charge going back into the Battery, it only dropped from 13.4...
