Lithium Converter Replacement Units

Step # 1

Determine the type and location of your present Converter/Charger. Note: There are two types of Converter/Chargers used in the RV industry Floor Mount and Wall Mount.

The Floor Mount unit is designed to be mounted on the floor of a compartment in the RV, but can also be mounted on a side wall or the ceiling and will operate normally.  Once you locate your unit, determine the model number and D.C. amp rating shown on the label.  Typical D.C. ratings are 30, 35,40,45,55, 60, 70 and 80-amps. These models are manufactured by Progressive Dynamics, WFCO, IOTA and Power Max.  Whichever model you have should be replaced by one of our PD9100L Series Lithium Models with the same D.C. output amp rating (See chart at bottom of this page). 

WARNING! Do not replace your present Lead/Acid Converter/Charger or Converter/Charger Section with a Lithium Model with an Amp rating higher than the D.C Amp output rating of your present unit as your RV wiring is may not be capable of safely handling this extra current!

The Wall Mount units as their name implies are mounted in the RV interior wall or cabinet for easy accessibility and include a removable Converter/Charger Section, a 120 VAC Distribution Panel with a 30 or 50 Amp Main AC Circuit Breaker and several 120 VAC AC Branch Circuit Breakers.  The unit also includes a 12-Volt DC Fuse Panel to supply 12-Volt power to all 12-Volt circuits.  Updating to a Lithium Battery System requires the removal and replacement of the present slide out Lead/Acid Converter/Charger Section with one designed to charge Lithium Batteries.  These Replacement Lithium Sections are available from our approved distributors.  NOTE: Lithium Replacement Sections are only available for Progressive Dynamics and WFCO Wall Mount units.

WARNING! Disconnect all 120 VAC power before removing and replacing converter/charger section!

The fourth photo on this page shows a typical Lithium Replacement Section for All Wall Mount units.  Replacement requires removal of the front panel of your present Wall Mount unit to gain access to the Converter/Charger Section.  Once Converter/Charger Section mounting screw is removed, (mark the location & color) of the wires then disconnect five colored wires and slide out present Lead/Acid section and replace with the new Lithium Section reconnecting the wires to their proper location.  Depending on your knowledge of electricity you may want to consult a licensed electrician or RV technician for assistance.

Step # 2

The size of the Lithium Battery you plan to install depends on how long you wish to dry camp.  This decision will be based on your experience with your present Lead/Acid Battery System.  Note: A Lithium Battery with the same Amp Hour rating will provide 2-3 times the battery power.  This should provide you with a guide to the Lithium Battery size you will require.  If you wish more dry camping time (off the grid) additional Lithium Batteries may be added in parallel to provide additional dry camping time you require.

Once you have determined the Converter/Charger Amp rating and Lithium Battery size, go back one page, then review our approved Lithium Battery distributor websites for pricing and delivery information.
