I currently store my coach in my garage plugged into 30 amp service. My new coach came with lead acid batteries. The coach has a progressive dynamics PD 4060 charger in a mighty mini power center. I am wanting to change batteries to lithium battle born batteries. Progressive dynamics has a replacement charger that outputs a constant 14.6 voltage but no 13.6 float voltage. Battle born told me not to leave this charger on constantly to avoid battery damage.Progressive Dynamics also offers a complete new mighty mini power center with a output switch to change from lithium to lead acid. Since I store my coach plugged in it seems this might be better since lithium charger could be switched off and charger would go to lead acid float of 13.6. Each choice is about equal in price.My question is how difficult are these choices to install and what choice is best. Thanks Progressive Dynamics was shut down for Covid so no help there.

I'd ask Battle Born support what they recommend based on your existing setup.If the PD 4060 charger can accept an external remote Charge Wizard Pendant, I'd keep the existing charger, add the pendant, and just manually increase the voltage up to Boost mode once in a while.From PD's webpage for their 4000 Series Chargers"Inteli-Power 4000 Series Mighty Mini models can recharge the battery to 90% in 2-3 hours using our patented Charge Wizard® technology.The built-in Charge Wizard automatically selects one of four operating modes: BOOST, NORMAL, STORAGE, DESULFATION.BOOST Mode 14.4 Volts - Rapidly brings RV battery up to 90% of full charge.NORMAL Mode 13.6 Volts - Safely completes the charge.STORAGE Mode 13.2 Volts - Maintains charge with minimal gassing or water loss."DESULFATION Mode 14.4 Volts every 21 hours for a period of 15 minutes to prevent battery stratification.

My solution was to replace the lithium/charge wizard jumper with a double throw switch. In the lithium position I get 14.6V to rapidly & fully charge the batteries. When full, I switch to the charge wizard & use the pendant to select the normal mode (13.6V), the recommended float by Battleborn. If I am staying with hookups, I only switch back to the lithium side ever 4-5 days to get 14.6V to balance the cells in the Battleborn batteries. I doubt I'd be losing much if I only charged at the charge wizard 14.4V, but it was an easy thing to do.On edit fixed float voltage...

I think you are fine with the existing PD converter. Also I understand the LI option does not hold 14.6 continuous but does drop voltage or shut down when the battery is full.

See battle born charging thread in Tech Topics forum. Everthing you need to know about charging BB batts and a BUNCH of nice to know stuff and links.

May I ask why you want LI?

From PD's webpage for their 4000 Series Chargers
"Inteli-Power 4000 Series Mighty Mini models can recharge the battery to 90% in 2-3 hours using our patented Charge Wizard® technology.

The built-in Charge Wizard automatically selects one of four operating modes: BOOST, NORMAL, STORAGE, DESULFATION.

BOOST Mode 14.4 Volts - Rapidly brings RV battery up to 90% of full charge.

NORMAL Mode 13.6 Volts - Safely completes the charge.

STORAGE Mode 13.2 Volts - Maintains charge with minimal gassing or water loss."

DESULFATION Mode 14.4 Volts every 21 hours for a period of 15 minutes to prevent battery stratification.
