How to Upgrade Progressive Dynamics Converter for Lithium RV Batteries Safely

Got a 15-year-old Progressive Dynamics converter that's starting to throw fault codes with my new lithium setup — worth upgrading or try making it work? I have a 2006 Lance 915 cabover that I recently upgraded with 2-200 watt Bouge solar panels and 2-100ah SOK lithium batteries.

The problem is I'm still running the original Progressive Dynamics converter charger that came with the RV, and I've learned it's not designed for lithium batteries. I'm worried about damaging my new battery investment.

What are my options for upgrading? I'm not sure if I need to replace the whole converter unit or if there's some kind of upgrade kit available. Any advice would be really appreciated since I don't want to mess this up! …more

How to Upgrade Your RV Converter Charger for Lithium Batteries with Gentle Care

Halfway through planning our three-week cross-country trip next month, I realized my PD4560 60-amp converter/charger won't properly handle the lithium batteries I'm installing. My existing Progressive Dynamics unit obviously isn't designed for LiFePO4 batteries - I can use boost mode to charge them up, but I know that's not ideal for battery longevity.

I just purchased a 30 amp generator and I'm wondering if it will have enough capacity to handle not just my current charger, but potentially a larger lithium-compatible unit. I'm considering upgrading to a 75 or even 90 amp charger to reduce charging times, but I need to make sure my generator can handle the load. I'm trying to figure out the actual AC amp draw of these higher-capacity chargers and whether my 30 amp generator will be sufficient.

What are the best lithium-compatible converter/charger options that would work with my generator setup, and how do I properly size the charger capacity to match my lithium battery bank? …more

RV Battery Draining Overnight? Find & Fix Parasitic Drain

The day after I installed that new solar charge controller last month, my RV batteries started mysteriously draining from fully charged to completely dead overnight. I've already confirmed that all visible lights, fans, and appliances are turned off, and I've switched off the main interior power, but something is still drawing power continuously. I understand this is likely a parasitic drain where some component or circuit is staying energized when it shouldn't be, but I'm not sure how to systematically track down which specific circuit is causing the problem. I have a basic multimeter but I'm not entirely sure about the proper methodology for testing each circuit individually to isolate where exactly the power draw is coming from. What's the step-by-step process for using a multimeter to methodically work through the electrical system, starting from the main disconnect and testing individual fuses or circuits until I can pinpoint the exact source of this parasitic drain? …more

RV Converter Not Charging Battery: Fix Guide & Solutions

Despite my multimeter showing 12.6 volts at the battery, everything I've read says my converter should be pushing 13.6 volts during charging. When I plug into shore power, my converter fan kicks on and runs like normal, and all my 120V stuff works fine - lights, outlets, everything. But my batteries just aren't charging at all.

I'm not really sure where to start troubleshooting this. Could it be a fuse somewhere? Bad connections? Or is my converter partially failing somehow? I'd really appreciate some guidance on what to check first and how to test if the converter is actually putting out the right voltage to charge the batteries. …more

Lead Acid vs Lithium RV Batteries: Complete Upgrade Guide

Pulled into my favorite boondocking spot with batteries that used to last three days, but now these lead acid units are completely dead after just one night! I've been running two 12V lead acid batteries in my travel trailer and I'm SO tired of dealing with their limitations - slow charging, constant maintenance, and they seem to die at the worst possible times.

I found these Dyness 12V 100Ah LiFePO4 lithium batteries and I'm really hoping they might be the solution I've been looking for. But I'm completely lost when it comes to lithium technology. Will my current converter/charger work with lithium batteries, or am I looking at more upgrades? I keep seeing mentions of something called a BMS - what exactly does that do and why is it important?

I just want a system that actually works reliably and charges properly both when plugged into shore power and while driving. Can someone please tell me if making the switch to these Dyness LiFePO4 batteries is worth it, and what I need to know about compatibility with my existing charging system? …more

Suburban RV Furnace Won't Work on Shore Power - Complete Fix Guide

Suburban RV Furnace Won't Work on Shore Power - Complete Fix Guide

Around midnight in the RV parts aisle staring at furnace components with no clue why my 2016 Heartland Bighorn's Suburban furnace acts totally different on shore power versus battery. When I'm running off battery power, the thing works like a champ - fires up, heats great, cycles on and off perfectly.

But the second I plug into shore power? It's like the furnace forgets how to do its job. It'll run for about 4 minutes, never actually produce heat, then shut off and lock out until I reset everything. The only way to get it working again is to disconnect shore power and cycle the battery.

I'm wondering if this is some kind of converter problem? Like maybe it's sending the wrong voltage to the furnace control board when on shore power? Has anyone run into this before and know what voltage levels I should be checking? …more

Georgetown GT7 Lithium Battery Conversion: Complete RV Installation Guide

Turned the keys on my 2023 Georgetown GT7 and discovered the previous owner left the electrical system in complete shambles, now facing this intimidating lithium conversion nightmare. I know I need LiFePO4 batteries, but every forum post I read mentions different components and I'm getting conflicting information.

I really want to make this upgrade work - the lead acid batteries are killing me with their weight and charging limitations. What specific components do I need beyond the actual lithium batteries? I'm especially confused about whether my converter will work and if I need additional charging equipment for the alternator. Please tell me my 2023 model year gives me some advantage here! …more

50 Amp RV Inverter Charger Replacement: Complete Installation Guide 20

Finally moved into an RV with a 20-year-old Tradewinds inverter/charger unit that's completely dead and I have absolutely no idea how to replace it. The repair shop is offering a used Magnum MS2812 (2800VA) for $700 installed, but I'm concerned about its actual charging capacity versus my requirements.

My RV is wired for 50A shore power service, and I need an inverter/charger that can handle the full charging load. The shop claims the MS2812 will work, but the specifications seem to indicate it's only a 30A charger unit. Are there any legitimate 50A inverter/charger options available under $1000, or should I be looking at different manufacturers like Progressive Dynamics or Aims for this price range? …more

Can You Remove an RV Inverter Charger Without Replacement? (Yes, Here'

Called three RV supply shops about replacing my failed Xantrex inverter/charger in my 2001 Fleetwood Expedition — but do I even need one or just wasting money? Since I never utilize the inverter function and rely exclusively on generator or shore power for 120V loads, I'm evaluating whether complete removal is feasible rather than expensive replacement.

My primary concern is maintaining proper 12V DC charging capabilities for house batteries that power lighting, water pump, and ventilation systems. Would installing a standalone battery charger provide adequate charging and maintenance functionality? Are there any critical system integration issues I need to address, particularly regarding power transfer switching between shore power and generator sources? …more

RV Lithium Batteries: Dual Purpose vs Deep Cycle for Coach House Banks & Performance

Despite watching countless YouTube videos on RV lithium batteries, I'm now more confused than when I started about dual purpose versus deep cycle for my motorhome's house bank. I understand that dual purpose batteries are designed to handle both starting and deep cycling applications, which sounds convenient for an RV setup. However, I'm wondering if there are performance trade-offs when using dual purpose lithium batteries specifically for coach/house battery applications where they'll primarily be doing deep cycling to power lights, water pump, refrigerator, and other 12V systems. Would I be better off with dedicated deep cycle LiFePO4 batteries for my house bank, or do dual purpose lithium batteries offer sufficient performance for typical RV boondocking and daily use? I want to make sure I'm getting the best cycle life and value for my investment in a house battery system. …more

RV Battery Water Loss: Why Some Batteries Boil More Than Others

Walked out to check my four 6-volt Interstate golf cart batteries in my 2015 Tiffin Allegro Open Road 32SA and there's dramatically different water loss happening across them after just 6 months. Visual inspection reveals continuous bubbling activity in three of the four cells in these problematic batteries, while the fourth cell and all cells in the other two batteries appear normal.

The RV remains connected to shore power continuously, maintaining constant charging conditions. Battery testing indicates all batteries are within acceptable parameters and would not qualify for warranty replacement. What diagnostic steps should I perform to identify whether this is a connection issue, internal battery failure, or charging system problem? Specifically, what voltage and specific gravity measurements would indicate internal resistance problems that could cause this differential water consumption pattern? …more

Best 2000W Inverters for Grand Design RV: Complete Installation Guide

Noticed my Grand Design's warranty paperwork doesn't mention inverter installations — would installing a 2000W inverter void my coverage completely? except my dream apparently involves wanting to run actual appliances without firing up the generator at 6 AM and becoming "that neighbor" at the campground! 😅

My TT came with the prewired inverter loop (thank goodness, because my electrical skills peak at changing light bulbs), and I know it's wired with 10/2 Romex that can handle up to 2000 watts. Now I'm drowning in inverter options and getting analysis paralysis.

I'm looking for recommendations on the best 2000W pure sine wave inverters that'll play nice with my Grand Design's setup. Also completely confused about whether to go with an internal ATS for simplicity or bite the bullet and install an external transfer switch. Help a fellow glamper out - what are the top models you'd recommend, and what's the real difference between internal vs external switching options? …more

Why Your Onan Generator Only Charges Lithium Batteries at 5 Amps: Troubleshooting Guide for RV Power Systems

Pulled into my campsite last night and discovered my Onan generator is doing something bizarre — it's only pushing 5 amps to my new lithium batteries. With my 2 300 watt solar panels installed, my Onan 4k generator is only putting out 5-6 amps to charge my lithium batteries, even when they're down to 40% state of charge. This seems dangerously low compared to what I expected.

I just upgraded to a PD 9360 converter when I installed my solar system, and I'm concerned something might be configured wrong. When I plug into my portable Growatt 2200 watt power station, I get 25 amps charging, so I know the batteries can handle more current. At midday, my solar panels were only producing 170-190 watts, which also seems low. I'm scared to keep running the generator if it's not working properly - could this low charging rate harm my lithium batteries or indicate a serious problem with my electrical system?

Should I be worried about safety issues? I want to make sure I'm not making things worse by continuing to use the generator for charging. …more
