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.
