We have a 2024 Eagle 321 RSTS. It has the Progressive Dynamics PD4560WI power center with the LA - LI switch. It even has a sticker on the front showing the switch operation and "Lithium Ready". The manual states the LI setting is single stage at 14.4v (not good really for my batteries). The 5W also has OEM Overlander 1 package which is GoPower 30a MPPT and 190w panel on the roof.
I replaced the cheap LA battery that came on the coach this year with two Epoch 105Ah batteries (in parallel). Also added the GoPower MPPT remote so I could add a custom charge profile from solar for the battery specs. The out the box Lithium setting produced Pack Overcharge warnings. Voltage was too aggressive for Bulk/Absorption and Float for the LI batteries.
I spoke by phone with customer service at PD about the LI setting on the power center/converter. They suggested I run the converter in LA mode with Charge Wizard enabled instead of switching to LI. This will give a normal charge voltage of 13.6v and in boost mode 14.4v. The LA "storage" or I guess Float voltage is 13.2v. That's typically going to be below my LI battery nominal voltage. They suggested if we did any off-grid camping, the next time on shore power, manually active Boost mode which puts 14.4v for 4 hours on the batteries. The solar MPPT would top off the batteries with adequate solar available. I believe when I spoke to customer support it was mentioned the newer PD4560 in a 2024 coach should be outputting 14.2v in boost. I guess they stepped down the voltage in newer ones? I need to check voltage on our first trip out.
At least 95% of the camping we do would be on the grid, but I wanted the option to stay at a Harvest Host and not have the Everchill DC fridge kill my LA battery, which it did once already. That said, most of the time our batteries are going to be substantially if not fully charged from shore or solar power.
My question for the forum is if we find the PD4560 just isn't good for the batteries, get overcharge warnings due to the LA storage mode going into sulfation protection every 4 hours at 14.4v or just not charging at all, has anyone disconnected their battery from the PD4560 and replaced it with a Victron IP22 charger? What are the steps?
Does disconnecting the batteries from the PD4560 harm the power center components? Will all the coach DC run from the PD4560 when on shore power or the batteries if the battery is not connected to the PD4560? It's not really clear from online researching, conflicting reports.
