Year make and model of your TT is not enough. It is enough to say that if you have the original converter, you probably do not have a lithium setting.
What make & model of converter do you have?
What type of camping do you do? This is important, as cold and heat affect lithium charging. I would continue to get smart on lithium batteries and their discharge/charge requirements, as well as heated lithium batts, before deciding on a brand/model of lithium batt.
