I am looking for advice, or maybe just reassuring confirmation that what I am thinking is sound.
I'm looking for a three stage battery charger that I don't have to worry about. I just want to start the generator, plug in the shore power cord, let it run for a few hours and get the batteries back up to 90 percent.

I have a 2005 Jayco Jayflight 27BH travel trailer with a IOTA DLS-3045 load center (I have verified that IQ4 is not an option on this unit). I almost exclusively dry camp with two 6volt Costco batteries and a Honda EU2000i generator.

I was thinking about replacing my charger with an IOTA DLS-45 with IQ4. Not sure why I'm focusing on IOTA except that it's the same brand as the load center. With the IQ4 it is supposed to be a true 3 stage charger. IOTA DLS-45

My other thought based on years reading this form is something from Progressive Dynamics in the 92xx series. But the 92xx series appears to have a remote pendant that I have to use to put it into bulk mode which I want to avoid. Progressive Dynamics 92xx

I am thinking 45 amp so I don't need to upgrade the battery wiring.
I have plenty of room behind the load center for a deck mount charger.
Solar will probably be a few years off.

Two postings I found here that mention exactly what I'm thinking about.

What are your thoughts?

“ I was thinking about replacing my charger with an IOTA DLS-45 with IQ4.”

Go solar now and stop thinking about battery recharging 99% of the time, and recharge to 100%.

The Progressive Dynamics PD9245C is a fine unit that would easily service your needs. It does NOT come with a remote control unit unless you order that. I have this charger in my mini motor home and know literally hundreds of others with same unit ... and have never heard any complaints.

I use a PD9160 with the charge wizard pedant, I don't think you can go wrong with the PD series as long as you have the pendant.

So far I have been able to get 9yrs of use from a pair of 6V GC2s combined with my PD9160 with charge wizard. Would consider another PD series if my current one quits.

With that said, Iotas, as long as you have the IQ4 pendant seem to have similar specs to the PDs. Don't think I have heard anything bad posted about Iotas with IQ4 pendant.

If you didn't mind upgrading your wiring, there is a surplus electrics outlet which currently has Iota DLS-90 units for $125, they are working "pulls" from some sort of equipment so they are selling as used.

Find that HERE, the IQ4 pendant is not included with that unit but the price is right for 90A..

I've installed a couple IOTA products over the years and like them. I'd install the largest charger your generator will power so it will charge faster and reduce run time.

I think the DLS-45 will serve you well.

I have the PD9245CV and it works fine and goes into Boost Mode as soon as I plug in my onboard Onan,and will stay there until the batteries are fully charged. I have the modified 14.8 PD9245-CV

Mine came from Best Converter with the pendent,I like this so I can choose how I want to charge my Batteries.

Forgot to mention, since you are considering a external "deck" converter, you can relocate the deck converter much closer to the batteries. This makes it easy to upgrade the wiring between the batteries and converter.

Just need a place handy to plug in the converter and opens up the option for a higher amperage converter. Then disconnect the old converter output at the fuse box and you can disconnect the 120V side of the converter from the breaker panel.

Thanks for the replies. So the PD will go in or out of boost mode without me having to monitor the charge current and flip it manually?

And Gdetrailer, the relocation of the charger is intriguing. My current load center is near the back of my 30 foot trailer. What would be involved if I was to move the charger up front closer to the batteries? Would I be extending the wires from my shore power cord where it terminates at the load center? I'm assuming since I'm extending 120v AC wiring it would be a smaller gauge than 12v DC wiring of the same distance. Are we talking something like 6awg or is that too thick and 8awg would suffice?

opnspaces,

Yes the PD will--but the pendant allows the user to trigger boost charging--and that is well worth having.

If planning to charge only to 90% I suggest investigating SiO2 batteries.

Regular lead acid charged to 90% will exhibit progressive capacity loss.
