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

RV 12V Auto Reset Breaker Size Guide: 30A, 40A, 50A Selection

Opened up my RV this morning to prep for our two-week cross-country trip tomorrow and the electrical system keeps tripping the breaker every time I run basic appliances! My RV's entire 12V system just died completely - no lights, no water pump, nothing. I've checked everything I can think of and I'm pretty sure it's the auto reset breaker that's failed.

I have a WFCO converter/charger setup with dual 6V batteries, but I can't get underneath right now to read what's stamped on the current breaker. I need to order a replacement but I'm not sure what amperage to get. I keep seeing 30A, 40A, and 50A options online but I don't want to guess wrong and either undersize it or waste money.

What's the typical auto reset breaker size for this type of setup? Is there a standard that WFCO usually pairs with dual 6V battery systems? …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

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

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

RV Red Warning Light: How to Identify Unknown Electrical Components

Woke up to find my RV's mystery electrical component glowing red instead of the green light the manual promised, and I can't even figure out what this thing is! In the picture I uploaded, you can see the component with the red warning light that just started appearing recently. I'm pretty sure that's not a good sign, right?

I'm thinking it might be some kind of detector or maybe part of the electrical system? There are so many gadgets crammed into these rigs. Anyone know what typically has red warning lights in RVs and what I should be looking for to figure out what this thing actually is? Would love to get it sorted before it becomes a bigger problem! …more

AGM Battery Won't Charge After RV Power Surge: Complete Troubleshooting Guide

AGM Battery Won't Charge After RV Power Surge: Complete Troubleshooting Guide

Wondering what tools and steps I should line up for tackling my dead AGM battery this Saturday after last week's power surge hit? Last week we stayed at a campground with terrible electrical issues - the voltage was jumping all over the place throughout our stay. Ever since then, my AGM batteries refuse to charge properly. They'll only get up to about 12.2V when they should be hitting 13.6V for a full charge.

I've been troubleshooting this for days and I'm honestly not sure if the batteries are ruined or if something else got damaged during those power fluctuations. The 120V side of things seems to be working fine, but clearly something is wrong with the charging system. Could the converter or charge controller have been damaged? How do I even test for that?

I really don't want to replace these expensive AGM batteries if they're not actually the problem. Has anyone dealt with charging issues after voltage fluctuations like this? What should I be checking first? …more

RV LiFePO4 Battery Upgrade Guide: Converting from Lead Acid Golf Cart

After three years with my 2003 Fleetwood Terra, these dual 6V golf cart batteries only die when it's above 85°F outside — perfect charge retention in cooler weather. I've been reading about LiFePO4 lithium batteries and wondering if I should make the switch. We're not full-timers - probably use the RV maybe 6-8 times per year for weekend trips and the occasional week-long vacation.

I keep hearing about the benefits of lithium, but I'm honestly not sure if it makes sense for our situation. My current lead acid batteries seem to need replacing every couple years, which is getting expensive. But I'm also worried about compatibility issues with my older Terra's charging system. Would really appreciate some guidance on whether this upgrade is worth it for someone with my usage pattern and RV age! …more
