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

How to Protect Your RV Alternator When Charging Lithium Batteries: DC-

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …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

Complete Newmar RV Lithium Battery Upgrade: DC-DC Charger and BIM Wiring Guide

Staring at my 2019 Newmar's freshly wired lithium upgrade with Victron BVM-712, Orion XS DC-DC charger, and Cerbo GX — finished yesterday but the system still isn't charging properly.

The main issue is I can't figure out how to properly integrate my existing boost switch with the new DC-DC charger setup while maintaining the ability to trickle charge chassis batteries. Currently, my Orion XS DC-DC charger flows only one way from engine alternator to lithium batteries. Should I replace the existing BIM with a LI-BIM, which would be in series with the 2/0 cable? Is there a control wire on the Orion XS that will allow flow from lithium to chassis batteries while on shore/inverter power?

I'm considering adding a 120V battery tender for chassis batteries, but want to confirm what modifications might be needed to my existing BIM. Can someone provide guidance on the correct wiring approach? …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

How to Install a Lithium Battery Manager Relay in Your RV - Complete Guide

Got my weekend planned to install a lithium battery manager relay in my 1999 Fleetwood American Dream Saturday — what should I have ready beforehand? I understand these relays are crucial for protecting lithium batteries from overcharging by managing the connection to the alternator, but I want to make sure I understand the complete installation process before I start.

I'm looking for detailed information on how these battery manager relays function - specifically how they disconnect the batteries from the alternator when charging isn't needed. More importantly, I need step-by-step guidance on the actual wiring process, including how to properly connect the relay between my alternator/converter and the new lithium battery bank. I'm particularly concerned about getting the fusing right and understanding what control circuits are involved in this setup.

This is a significant electrical modification to my RV's charging system, so I want to ensure I have all the technical details covered before I begin the installation. Any comprehensive guidance on the complete process would be extremely helpful. …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.
