    Another DIY Portable Power Pack

    It indicates your state of charge by measuring the current flowing in or out of the battery. Doing so by looking at voltage is practically useless when using LiFePo4 batteries (and is tricky even with LA). Most shunt systems also come with a voltage monitor that attaches to the positive battery...

    Getting solar power under the hood of my 5th Gen 4Runner

    I think something like the solution adopted in this thread (user picture att for reference) may be very helpful for you. You can put a SAE connector, a Powerpole connector or any other solar connector you prefer. There is space to accommodate most of them short of say something like a SB50...

    Anyone using the Suaoki G500 to power a fridge?

    Newer model Goal Zeros do. I believe all of their X series has regulated 12 v regardless the size.

    Redarc BMS 30, not for use in Cold temps

    I believe Battle Born also has the internal heating lithium battery option, but those are only on offer (for now) for their OEM offerings and tieups with some RV and trailer OEMs.

    Redarc BMS 30, not for use in Cold temps

    Yeah it checks most of the marks if you are looking for a combined system. But these days you can build a best of breed system for far less and one that is more optimized for one's needs. But as you said if you don't have space to put 2-3 individual components then that becomes an issue and may...

    Redarc BMS 30, not for use in Cold temps

    What a bummer. A $1200+ system which I assume will shut absolutely all forms of charging below a temperature threshold (which is quite high from what I can make out)? I was once considering this for my build but was a bit reluctant about placing most of my charging bets on one piece of hardware...

    What is the best portable power? Yeti, ARK? Is there another?

    That really depends on things we don't know about how you intend on using it. As an exercise, determine your best case and worst case battery consumption with some margin for growth as we all tend to add stuff down the road. Once you establish that, try to see what an optimal AGM or LiFEPo4 bank...

    What is the best portable power? Yeti, ARK? Is there another?

    I agree. But there you are sitting at almost 70% of the cost of drop in LiFePO4 when you factor in usable capacity so it would begin to look less attractive relative to the more affordable AGMs. When I built my system, I paid around $520 (delivered) for Battle Born 50Ah after calling them and...

    What is the best portable power? Yeti, ARK? Is there another?

    Most of these (with the exception of Dometic) do not use LiFePO4 chemistry but use LiIonNMC . It is not going to be easy to open these units up, isolate the fault and then find a suitable component that will fit exactly and then perform the same. These aren't modular DIY units nor are they...

    What is the best portable power? Yeti, ARK? Is there another?

    Nearly 70 lbs for around 27 Ah of usable capacity. Plus slow charging. If you want the affordability of an AGM system at the expense of capacity and portability, I would suggest you build something around say a Trojan deep cycle AGM. You should be able to pick up a 90-100 Ah AGM for around...

    Battery Monitor

    Been using it for a couple of months and love the functionality and the app is pretty intuitive.

    Suggestion for a battery charger

    Could you be a little bit more specific? Do you want to install this charger in one of your vehicles or RV? Do you want it to be portable etc.

    What is the best portable power? Yeti, ARK? Is there another?

    The DC-DC is only charging my house/box battery. It's the solar that is capable of charging either. The DC-DC charger is located in the rear of my vehicle and is connected to the starter battery via a fuse block that I have installed in the jack storage area of my vehicle. I connect it to my box...

    What is the best portable power? Yeti, ARK? Is there another?

    Yeah that wouldn't be a bad idea though if you want both an AC to DC and DC-DC charger in there then you would have to get a little more creative as it will be a tight fit (you may have to find a smaller battery than the one I used). I use my AC-DC charger to charge both my starter AGM and this...

    Installing Renogy DC-DC charger in 2018 F-150

    The Victron units are pretty straight forward to wire up. An input side and an output side for your DC-DC and I think you can even wire up an ignition on connection just like you can on the Renogy, or the Red Arc for that matter. All connections are standard terminal crimps and no soldering...
