    The Lithium with BMS is actually safer for powering devices that must always be on like bilge pumps. If the LFP battery is run down, the...

    wholybee replied to the thread ABYC standards.
    I have not every heard of a boat needing to be signed off by an ABYC inspector. I'm not sure such an inspector even exists. Most...

    wholybee replied to the thread Audible Alarm BMS?.
    Before E-13 was released the discussions I read were using examples like an electric powered boat that suddenly lost propulsion in tight...

    To truly alarm before the BMS disconnects requires a BMS that has that feature, and that will always only be on the more expensive BMS...

    wholybee replied to the thread Audible Alarm BMS?.
    ABYC does not require such an alarm. You could have nothing and still be ABYC compliant. ABYC does has a recommendation for one, but...

    wholybee replied to the thread What's the best BMS?.
    Yes, I know that, but when you order a 120A BMS from a cheaper source, maybe you really get the 80A and never know unless you remove the...

    wholybee replied to the thread What's the best BMS?.
    200% might seem like a lot. But it's $50 on top of a battery bank that may cost thousands. And the risk is real. I bought "the same" JBD...

    wholybee replied to the thread Victron shunt suggestion.
    I think you are wrong in assuming it will be low cost. That is the main thing. The smart shunt is a very limited device. It doesn't even...

    wholybee replied to the thread Lifepo4 voltage.
    What brand batteries, and do you have a way to see the individual cell voltages? If you disconnect the 4 batteries, are they all charged...

    wholybee replied to the thread Victron shunt suggestion.
    It's a relay. With both N/O and N/C connections. In my other post, I said that you can connect the battery to the common terminal, and...

    wholybee replied to the thread Victron shunt suggestion.
    Just looked up the EC-AGS+. See page 13 of the manual, it supports a remote start/stop switch. Connect that to the relay on the...

    wholybee replied to the thread Victron shunt suggestion.
    But they must also have other controls, a remote start, a generator disable, etc. For sure, the Onan generators I have seen absolutely...

    wholybee replied to the thread Victron shunt suggestion.
    So there is no way to manually start the generator except by opening the panel on the side of the RV? There is no control panel inside...

    wholybee replied to the thread Victron shunt suggestion.
    Then use 2 resistors to make a voltage divider. I'm not that familiar with many generators, but don't most have a remote start...
  • W
    wholybee replied to the thread Victron shunt suggestion.
    Yes, it exists, more or less. The Victron BMV-712 (which is similar to the smart shunt but has a display) also has a relay output which...

    Do you know what those 2 switches do operationally? One of them will probably select from battery 1,2, or both. But sometimes people do...
  • W
    True. Either use "tefgel" or plastic washers to insulate the differing metals. Tefgel works great, I use it everywhere. I have lots of...

    If you are referring to the hangers that are a round clamp with a long bolt, then I would think they would be fine. Similar to what I...

    These are rigid panels? They already have frames, and I would utilize those before adding more weight and complexity. They don't need to...
