After re-reading my link, I think I missed that the question was for an older lead-acid center w/o the lithium switch.

Funny thing, I got a reply from Progressive Dynamics, and I asked if the PD 4575 will charge my Lithium the exact same as a PD9160Alv and his reply was "I don't know the charge profile of the 4575!!!! So I replied, can you tell me who knows these 2 units to tell me the charging similarities or differences.

Hoping whomever sent my message to their ask a question website , or he, can re-route my question to someone who does know the answer, LOL.

Very frustrating he answered me vs hand it to someone who knows the answer.

I may have to ask Battleborn to answer this, as they do sell them and mention they know which are best. I had hoped Progressive could answer me the best.
