Lithium Replacement Converter

I am looking for a replacement converter to charge my 300 amp/hr lithium battery bank. I favour a deck mount style and see several on Amazon but am really confused by their lack of info about them. I think I need a 75 amp, 2 or 3 stage. Can someone suggest a brand and model that has worked well for you?

Progressive Dynamics PD9380 deck mount 80 amp, 2 stage converter. Not cheap but works great!!!!
Don't buy a pendant as one comes with it (but not mentioned in the product description).

I replaced my house batteries (2 12v deep cycle FLA) with one 12v 300ah LifePO4 battery. The existing charger (Progressive Dynamics) has a jumper to change the charging parameters for LifePO4. So far it's working well. I can monitor the voltage through the Incommand System.

my charger is from early 2020 and does not have the capibility change to lithium. i was going to change it out but when i called progressive the tech tofl me just use the charge wizard way to charge the lithiums. i just hold the button when i need to full charge then it will charge at the higher 14.4 rate until full. it has worked fine this way rather than spending the cash to get a new one , here is the page for it.https://www.progressivedyn.com/chargewizard/

We have a PD4575K18LS8.
I do the same thing as Ahdmeyer before and while boondocking to get a full charge on our lithium batteries.
