Question:
Hello, I have Progressive Dynamics power converter PD4135KW2, installed March 2019 and doesnt have the lifep04 charging option. I just upgraded to lifep04 battery and need to replace my power converter. Do you have a replacement converter that will fit.

Hey Christopher, thanks for reaching out!
You might actually have a lithium setting on your current model that will allow it to work with a LifePO4 battery bank. If you check out the linked photo you'll see what I mean.
If you aren't able to do any of this, then we'll need to get you a replacement center with part # PD4045KA rated for 45 Amps.
Let me know if you're able to mess with the switch or wiring as opposed to getting a whole replacement unit!
