PD4500L Series Lithium Power Centers

PD4500L Series all-in-one Lithium Power Centers.


Output Voltage 14.6 Volts provides full & rapid recharge for lithium iron phosphate 12-Volt batteries.

Reverse Battery ProtectionPrevents charger damage if battery connections are accidently reversed.

Provides Filtered DC Power – Ensures proper lithium Battery Management System (BMS) operation.

Electronic Current LimitingAutomatically reduces output voltage to prevent overheating and possible damage if current limits are exceeded.

High and Low Voltage Protection Prevents charger damage from AC input voltage fluctuations.

Automatic Thermal ProtectionReduces charger output to safe levels if unit temperature exceeds the pre-set temperature limits and protects charger damage due to excessive heat.

Quiet Intelligent Cooling FanOnly operates under high load conditions.

2-Year Limited Warranty – Progressive Dynamics Power Centers are designed tested, assembled and serviced in the U.S.A.

Note: All models provide the Constant Current/Constant Voltage (CC/CV) charge profile as recommended by lithium battery manufacturers.


The PD4500L Series are all-in-one power center units that include a 50-Amp 120VAC AC distribution panel, a 12-V DC fuse panel and a 60, 75 or 90-Amp lithium converter/charger.

RV manufacturers can easily update their models to provide the advantages of a lithium battery system including the following:

Faster recharge from both converter/charger and solar charging systems. Fully recharge a lithium 100 AH battery in 2-½ hours vs. 6-12 hours for lead/acid.

Longer battery life, up to 5,000 recharge cycles vs. 300-400 for lead/acid.

Up to three times the energy as compared to a like sized (Amp hour rating) of a lead/acid battery at approximately ½ the weight!

No battery maintenance required and they do not have to be charged during storage.
