Hi

I have a YETI 1500X with a Yeti Link Vehicle Integration Kit.

The EC8 12 ft. Extension Cable that it comes with is too long because i lose 300 watts.

I can get 800 watts without this extension.

I thought about extending the red cable but I'm a novice so I'm wondering what other solution do I have?

    @anti,

    How far of a cable run do you need to make to connect the Battery to the Yeti?
    Be careful. Lots of current flows through those cables (up to 75A in some cases).
    If you are loosing 300W using the extension, it does not just disappear, it may be turning into heat. Please verify all your connections are very tight and you have clean metal at all connectors.
    I would consult a custom vehicle installer for help.

    I try to be as careful as possible and that's why I'm talking to you ;)
    We would have a length of 50 cm maximum

    The male EC8 cable from the Vehicle integration Kit is 99cm long already.

    How much longer are you thinking that red ring to ring section would need to be?

    50cm just for the red ring to ring

    Any time you extend the length of a circuit or are experiencing a power drop, its a good idea to increase the thickness and strand count of the wire to give those electrons more surface area to travel on.

    It looks like there are some ready-made options on Amazon.

    This one is 24"(60cm) 6AWG SAE 105C rated cable with already crimped 5/16(8mm) size rings that are silver plated.
    https://www.amazon.com/Single-Copper-PowerFlex-Battery-Inverter/dp/B072MWHC1T/

    8AWG is the size of the original cable but I think 6AWG (which is larger) is a better size for that setup.

    Based on this table that cable should be able to handle 121A

    105C is the rating of the isulation on the cable. The higher the temperature rating the better the cable is at conducting max current rating for the metal without losses.

    Hello again

    Sorry to give news so late.
    A lot of energy to balance at the moment, and we are not talking about electricity, but the energies of man, of the Earth, of life.

    So a specialized electrician (stumbled upon him) made the modification for €30.

    He lengthened the small extension cord (with the fuse), increased the cable sections, etc., I showed him your message.

    Result now I have minimum 700 watts, on average 750 sometimes peaks at 800 :)

    I thank you again and really very much for responding so quickly and precisely while trying to help me on my own.

    Sincerely good Job GOAL ZERO.
    We love your brand.
