    LiFePO Batteries ???

    The AGM battery will be supplying voltage to the DC to DC converter until: 1) The DC to DC converter detects that the alternator isn't operating...voltage below setpoint. 2) The LiFePO4 battery gets fully charged which is around 14.2V to 14.4V 12.8V is not the LiFePO4 battery voltage. Lithium...

    LiFePO Batteries ???

    The alternator output has very little ripple...50mV is typical. The DC to DC converter does not care about that. It also doesn't need a battery to dampen voltage. Many DC to DC converters are driven straight off alternators. However, it needs to be a smart alternator to be used without a...

    LiFePO Batteries ???

    Since you are worried about the temps of the batteries, you should be equally worried about the temps of the equipment that is charging them and the inverter. All should be operating in an environment less than 140F. Also, the batteries should be as close to the inverter as possible so if you...

    LiFePO Batteries ???

    LiFePO4 is a Lithium Ion battery. There are many subtypes of lithiun Ion batteries....one of which is LiFePO4. https://en.wikipedia.org/wiki/Lithium-ion_battery Go to the Battleborn battery site...one of the pioneers of drop in LiFePO4 batteries. The home page even calls them lithium Ion...

    LiFePO Batteries ???

    EDIT: I forgot that the Renogy unit does have circuitry that detects when the alternator is charging. Was thinking of the stand alone Renogy DC to DC converters.

    LiFePO Batteries ???

    Another BTW... ...When I am not using my trailer, I store them at around 60% state of charge. They self discharge very little and would self discharge even less if I disconnect the Victron MPPT which draws around 25mA. I bought the Victron IP43 50A charger which also supplies my trailer when I...

    LiFePO Batteries ???

    The Epoch are better built than any of these other cheap batteries. There are some videos that show how they are built. They also have heaters if you chose to use them for cold weather charging. For example, until recently, LiTime didn't have cold weather protection in their BMS so you could...

    LiFePO Batteries ???

    A lot safer than lead acid batteries under the bed.

    Maybe my turn for new boat time

    Let me know...can print it in a rubbery type material too.

    LiFePO Batteries ???

    Also...I highly suggest the 50A DC to DC that Victron just came out with. I just bought one for my trailer. I would NEVER EVER use Renogy equipment. I don't see it in your diagram you should add a battery monitor like a Victron Smart Shunt or BMV-712. The main reason you go with two separate...

    LiFePO Batteries ???

    I love lithium batteries...have them in my travel trailer. In fact I made 2 280AH batteries myself for my trailer. Personally, if were to buy a couple batteries today, they would be the Epoch batteries....especially the 460AH ones. And for the naysayers, LiFePO4 are probably safer than lead...

    Bunk Boards or Guide Poles?

    I used to have side bunks on my 24' Wellcraft. My newer 26'Cobalt doesn't have them and I don't miss them since I have almost no wind ever at my launch ramp and I only need to launch/retrieve once a season since my boat sits in the water all summer. If you aren't like me and have wind or...

    Maybe my turn for new boat time

    3D printing to the rescue. I love my 3D printer. Give me dimensions and I will print a shim for you.

    Need to add trailer brakes

    Do yourself a huge favor. If you travel any distance at all, install disc brakes...preferably a good brand like Kodiak. I hate drum brakes...both by 26' boat trailer and my 25' travel trailer have disc brakes. They both happen to be EOH but surge and disc are fine on a boat trailer.

    Getting ready for the ice and cold in central Texas!

    It is getting colder in certain areas because of warming in other areas that has never happened before. You get unusual warming in the artic and it forces cold air further south than it ever occurred before. Climate change is causing extreme temperature variations. And yes, when it gets...

    Funny how people don't understand that weather and climate change are two different things. https://www.usgs.gov/faqs/what-difference-between-weather-and-climate-change#:~:text=Weather%20refers%20to%20short%20term,refers%20to%20long%2Dterm%20changes.
