Batteries are expensive and I don’t trust the voltage from my old converter. Maybe it would be ok, maybe not. After looking at the cost for a new converter, an inverter, and a soft start for a/c I decided to try the Multiplus. I had never heard of one before being educated here. The...

Are you using eg4 batteries? If so what do you think?

Well, looks like I’ll be adding a Multiplus 12/3000 original design. Looks like I’ll be adding a Multiplus based on experiences shared here. Thank you for taking the time to share what you know.

Do you use a soft start on that 15k a/c?

Do you use a soft start on the a/c? I have a 15k dometic penguin and if I can do without a soft start I’ll put it toward a Multiplus :)

I’ve been looking into the Multiplus. Do you think the power assist will help start an air conditioner? I’ve seen some people say the Multiplus will shut down but I wonder if it is a matter of user setting choices.

My vestwoods pow bank app doesn’t show battery discharging unless it’s at least 2amps. I think this causes the app to report a higher battery charge % than it should. Have any of you had this experience?

The stored energy is about $1.50 worth of electricity so a/c may use it up in a day. If you don’t use the a/c and you have LED lighting, I’d guess a week. It sounds like a nice setup to me.

Yes mine also showed around 50% but was really under 30%.

Yep, looks like power must be applied to wake up the vestwoods battery. My new charger arrived, I hooked it up and the app is reporting data now. Thanks

I ran across your discussion separate from this one. Did you mention a need to “wake up” the battery? Maybe this is what I’m missing…

In all cases after clicking on the battery serial number in the app all I get is a spinning icon. I used the vestwoods app followed by the pow bank app. For android it was the pow bank app.

I have just one battery. It is advertised to be used with a Bluetooth app. which I downloaded. The app finds the battery but no telemetry is shown. I have done this by scanning the barcode on the battery as well. Since I use an iPhone I had a friend try with an android phone….same...

Has anyone used the vestwoods battery app for their line of batteries? I’ve tried without success.

Is yours the 3000w model?

Nothing so far. I run a generator when needed but I guess I’ll need to look at inverters soon. Any suggestions?

The best deal I found was a Victron ip67 25A so I’ll give that a try. I think it’ll meet my immediate needs and members here recommend the brand. Thanks to all of you for the helpful advice!

I just looked at Victron. Is the ip22 a better choice than ip67?

Interesting……eliminating the converter may result in better battery charging. Does anyone have experience with this type of charger?

Looking for recommendations for a new converter. Upgrading to LiFePO4 in a travel trailer. Existing converter is Magnetek 950 rated at 50A 12V. Thanks for any help!

I plan to replace the converter with a new charger.

There’s lots of room for batteries in the old airstream. The previous owner removed the drawer under the sofa which is very near the converter and dc distribution panel. I could fit anything a foot tall and 5 1/2 feet wide there. Three server rack batteries would fit but I am advised to use...

Thanks for the help. I’ll be shopping around for 12v battery options.

Its an old Airstream. I want stored power so I run the generator less. I’d just run the fridge (aftermarket 12v only) off the new battery. Seems like 1KWH a day should run that. If I need 120v I’ll run the generator and recharge at the same time. I don’t remember if 120v is needed for the...

The battery will be charged with a generator as the RV is parked in the shade when camping and solar would produce little. I’d like to power the fridge and furnace controls with stored energy and run the generator every few days to top off. I’m thinking the server rack battery has a good...

Looking for input...I’m replacing the old lead acid 12v battery in an RV with a server rack battery. My choice is between a 12v 400ah or the 48v 100ah with a step down converter to run the 12v RV fridge. I expect losses in the converter but don’t know how much. Thanks
