    Airstream Basecamp LiFePO4 Conversion System Feedback

    Thanks, by reliably I mean that I got it to work once and never again (no 12V coming from vehicle. I will retry the different iterations in the video as part of the debug. . Also, I am wiring both the positive (black) and negative (white) from the 7pin into the orion and putting the output of...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    Thanks for the feedback everyone. Just completed the battery install. still waiting on more time away from work to do the inverter side of things.... I am having trouble getting my F150 to detect the trailer and trigger the alternator with the DC/DC charger installed. I don't really care...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    @HRTKD I am looking at settings for my Multiplus here is what I am thinking.... Low Voltage Cutoff: 12V (~10% SOC) Float: 13.4V Absorption: 14.2V Charge Current 120A I think these are pretty standard... is this similar to how you configured? Any gotchas?

    Airstream Basecamp LiFePO4 Conversion System Feedback

    1. Thanks, I was wondering about that. 2. Sounds like I will just go 2/0 on everything from the batteries. The one question I have is that between the negative terminal and the BMS. It looks like you used 3x4awg?? Current connected sells the 2x6AWG kit for the BMS I found a formula on...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    Based on the feedback I think I am going to give the EVE280Ah Cells a go. I updated the schematic with important wire sizes and stuff. I think 4AWG should be sufficient for each battery right (150A BMS)? Since the space I have is relatively small 25-27" W x 16-18" D x 17" H I plan on cutting...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    Thanks for the info. It seems there is a large disconnect between storage conditions from cell manufacturers to battery vendors. Both BB and SOK say storage to 140F whereas the cell storage from EVE is much less. At the end of the day it is the same chemistry right? It almost makes me want...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    Thanks. Still evaluating my options here. I think the dimensions of the space and climate are complicating things for me a bit. I think I am still planning on going with the EVE 280Ah cells but just trying to make sure I do my due diligence. It sounds like I will need to build some sort of...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    @HRTKD Do you have a schematic of your system? After doing some more research I may want to go with 560Ah of eve 280 cells (4s2p). Seems like it is a similar footprint as the GC3.0. Essentially all I will need to do is build the battery, top balance and install (still doing research)? Should...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    Weird. I see it in the 12/3000 manual but not the 12/2000 manual. Based on the ratio of power between the 3000/2000 ~250A should be sufficient.

    Airstream Basecamp LiFePO4 Conversion System Feedback

    Also since max wattage is 1600 for the inverter I was thinking a 200A fuse would be sufficient. Peak power of the inverter is actually 4000W I'm not sure the characteristics of the fuse but should I fuse to hit 4000W peak (~400A when accounting for efficiency losses)?

    Airstream Basecamp LiFePO4 Conversion System Feedback

    That is the charge controller that came on the trailer. Not sure I will upgrade the solar on the rooftop yet but I do have 3x200W renogy suitcases that I run through a bluetti AC200 to provide power to the trailer (left from my old setup). Microwave is 1150 input watts so I am guessing I just...

    Airstream Basecamp LiFePO4 Conversion System Feedback

    Hi All, Just starting my build design for our new Airstream Basecamp 20x. The trailer already has 180W of solar on it but I want to convert from AGM to LiFePO4... See attached diagram as my starting point. I think I still need to add some fuses for protection. I plan on putting in an...
