If I am following correctly you have a complete system in place already but bought new lithium chemistry batteries and want to change out the previously installed with the new Battle Born. If the solar charge controller you refer to is the Go Power PWM, # 34276119 then there is no need to change this out as it works with sealed/gel, AGM, and flooded lead acid, and lithium iron phosphate batteries. You will however need to select the correct preset charging profile for your type battery.

Your inverter is fine as it is irrelevant what chemistry of battery it is used with.

If your smart battery charger that is used when on shore power is the Go Power RV Converter and Smart Battery Charger, # 34266170, this is not compatible as it is for flooded lead acid and AGM batteries only. Please verify what charger you have. If your current system functions well, you simply want to remove and replace the components necessary to support the new battery type, this will need to be changed. You do not identify what AC/DC panel you have. One option, and what I suggest, is to replace with the Progressive Dynamics RV Power Control Center, # PD4590K18LS8. This is a 2-in-1 AC/DC distribution panel and converter charger that supports lithium-ion, flooded lead acid, AGM, and gel batteries.

We do not have a network of installers that are recommended however, any reputable RV maintenance/repair will be able to take care of these items for you.

No wiring diagram needed for batteries, simply connect them in parallel. This will provide a 12 volt 300 amp hour battery bank.

Hey Dave. The Go Power RV Converter and Smart Battery Charger - 12V - 75 Amp item #34266170 does require a 120 V 3 wire grounded source for the AC plug, which is typically a dedicated 20 amp single service breaker. The Progressive Dynamics 9300…

You will need a different converter charger if you are going to lithium batteries, which is what I believe you are asking. The right one will depend on how many amp hours you need though, like the 100 amp-hour #34282738. I have added a link below to…

Hey Andrew! Yes, Furrion does have a Chill Cube model with a heat pump. This was actually just released for aftermarket sale. You will need a complete system to make the switch, new R32 units aren't backwards compatible with old R410A systems.…

Natalie, that depends on how your RV is set up. If your existing power center has a converter that isn’t lithium-friendly and can’t be replaced on its own, swapping the entire power center can be the cleanest solution. Units like the PowerMax 45A…

The Progressive Dynamics 2000 Watt Inverter w/ Transfer Switch #PD64FR is simply our part number for the PD1620A. We do not always use the manufacturers part numbers as our own since we have so many different manufacturers we carry.
