  1. Steve in Fla

    I have ordered both an SOK Battery (206AH) and a Multiplus II. Both times shipping was ridiculously fast! Sucker had a label on it and tracking mailed to me within 2 hours! Cannot stress enough the value added to an SOK or Victron purchase from these folks.

  2. Robert Makowski

    bought a SOK Battery (206AH)w|Bluetooth and heater and it was shipped within a week. I had planned on purchasing a Victim Multi plus II but was told that I would need two or three batteries for it to work properly. I am very disappointed but glad Dexter explained why it wouldn’t work in my configuration.
    The support is awesome. Thanks Dexter for taking time to explain things to a solar newbie.
