RE: Converter Question
Yea, I wasn't thinking of a diode. I have 1 on my little 1A float charger. I can add a 30A or better schottky to this.
The output of the IOTA is adjustable by adjusting pot P1 on the board. However, the trip point using the IQ4 is still 14.8V and it will never get there if you adjust P1 to 13.2V before connecting IQ4.
My battery charger for several years now is an old 20A HP power supply. So I've been doing it manually for years.

RE: Converter Question
As time2roll pointed out, the IOTA floats at 13.6V, same as my WFCO. A bit too high for camping in the heat. This boils my batteries over time.
With the IQ4, the IOTA bulks at 14.8V, absorbs at 14.2V and floats at 13.6V. It's my understanding this profile is too high for my Johnson Controls 29DC batteries. iski4fun`s batteries may better handle these higher voltages long term.
My $70 IOTA with IQ4 will make a nice multi stage bench charger/power supply but I'm not replacing the WFCO with it.

RE: Shower WOnt drain if Gray valve is shut
Preface, my motor home is a bit off level to the front How much is a bit? Being too much off level may not be good for your fridge either. Level it and see if the problem persist. If you are nose down and the vent pipe enters the tank at the front, this could be your problem.

RE: RV Airflow
This technique helps too if there's gaps where the ceiling panels meet the duct work.I had the same issue in my Keystone Outback. Solved it with duct tape. On top of that, the ends of the ducts were open, blowing air into the ceiling gap. I had to block them off with cardboard.

RE: LED or other upgrade for 12v fluorescent light?
Home Depot has a variety of warm tube sizes. Would they not work if they have the proper size?

RE: RV Airflow
Don't beat yourself up Old-Biscuit. I'm sure this company is buried in some serious debt at the moment. They probably spent or borrowed a million $ to get to this point. Molds are not cheap. It will take some time for them to realize a profit at this price point.
I would be hard pressed to give up my chill grille. It's almost required down here in Texas. One of the main reasons we are winter campers is the AC doesn't keep up and there's not much we can do about it. I would try one of these for $75, but not $175.

RE: Converter Question
I received my IOTA today. It measures 13.52V on my calibrated Fluke. It's advertised as 13.4V on the enclosure label.
I'll order the IQ4 tonight
Thanks again for bringing this to my attention. I'm always looking for a deal.
On Edit: I realized this morning the 13.52V I measured last night was at the battery. The voltage this morning at the IOTA output is 13.60V and 13.58 at the battery.

RE: Converter Question
Sorry I hijacked your thread iski4fun.
Do yourself a favor and buy one of these IOTAs. You can't beat the price, and I believe you will need one. If you're not comfortable putting a 120V plug on it, find someone that can.
Even without the IQ4 controller, it's better than what you have. My WFCO converter puts out a constant 13.6V and I've lived with it for 7 years. You just have to be careful to not let it boil your battery.

Thanks for the heads up
According to the description and video, it's IQ4 compatible

RE: Converter Question
WOW that IOTA is a deal. I grabbed 1 to replace my WFCO junk. 30A is all I need.
The IQ4 upgrade is $20 on Amazon
Thanks for sharing

RE: Converter Question
It would not be outside.
Gdetrailer gave you some good places to look. He is correct that some manufacturers use the circuit breaker he illustrated as a convenient terminal block.
Start at the positive battery terminal and work your way back, following each wire. You should find that breaker. Follow any wires connected to it. Your emergency brake switch would be in this path as well.
There is a good chance a previous owner removed it. The electrical tape wrapped on the bundle in your last pic doesn't look factory installed
Look at the bright side, you're learning a lot about your trailer :)

RE: Converter Question
This may help
Follow the wire from the "B" connection above the fuses or the positive cable from the battery. If there is a converter it will be connected to them.

RE: Pure sine wave inverter suggestions?
I'm sorry I got your hopes up only to tell you this converter won't work for your application.
2 problems:
It's only good for 360W at 12V
If you do indeed have a smart charger, you can't replace it with this converter and expect it to work without developing additional circuits. The BMS tells the charger what to do.
We were debating if you should without determining if you could.
FWIW: I have 3 of these converters in use for different purposes without issue. One boosts my TV voltage to my FW battery to a constant 14.2V to recharge my battery while driving if needed. I have a toggle switch to remove it from circuit if not needed. Another in my boat to recharge my 24V trolling motor battery bank. The third runs a 48V hoist. I have a fourth on the shelf as a spare but haven't needed it.

RE: Pure sine wave inverter suggestions?
What's your charge current requirement? Are they lithium batteries with internal battery management system?

RE: Pure sine wave inverter suggestions?
I think that thing generates 150kHz DC pulses and smoothes and regulates them to a higher DC output voltage very efficiently. It's a DC input switching power supply. Going through an inverter to create true AC, and then an AC to DC charger is an inefficient, but simple approach. Maybe 70% efficient at best.
So you are saying that generating modified wave and stepping up voltage is not making it inverter?
I tought I know something about electricity, but evidently not. Maybe our definition of an inverter differ.
Regardless, I was just pointing out an efficient alternative to OP if it meets his power requirements.

RE: Pure sine wave inverter suggestions?
I need to charge an electric dirt bike. Its charger is AC only and I will pay the extra for a pure sine wave inverter. I had a MSW inverter for my microwave and it really did not like the MSW.
My CPAP runs from 12VDC.
Thanks all.Why not just boost the DC with something like THIS? There is a lot of loss converting DC to AC then back to DC
That's an interesting product. Thanks, I'll look into it.
What do you think that thing is?
DC to DC chargers are inverters with converters in the same unit.I think that thing generates 150kHz DC pulses and smoothes and regulates them to a higher DC output voltage very efficiently. It's a DC input switching power supply. Going through an inverter to create true AC, and then an AC to DC charger is an inefficient, but simple approach. Maybe 70% efficient at best.
