Hi Folks, I've now sold my Prius on so I have my Prolong charger/discharger for sale. I purchased it direct from Hybrid Automotive in the USA at a cost of $771.39 I have only used it 3 times as I replaced two cells on my battery, balanced the battery and it then ran fine. I unfortunately forgot to remove the wiring harness so it is only the charger/discharger but you can purchase another on their website for $150 The items are in as new condition. selling for £450
