There is no discharge curve in any of the material on the Victron site for the Supercylce batteries. I was hoping to see how these compared to Lithium. Has anyone else come across this information? I have been quoted a ridiculous amount to convert from my AGM batteries to Lithium, so wanting to see if this would be a happy medium. I like the idea of lithium as the volts remain well above 12v for at least 80-90% of their charge, which in turn is good for all the instruments and electrical components on the boat.
