The reason you get assert is because you didn't specify the sign.

I have fixed it.

  procedure Test;
  var
    arrBytes: array[0..15] of
    byte = (159, 245, 94, 199, 119, 153, 43, 128, 135, 251, 91, 211,
      154, 145, 184, 255);
    aBytes: TBytes;
    r, s: TBigInteger;
  begin
    SetLength(aBytes, Length(arrBytes));
    Move(arrBytes[0], aBytes[0], Length(arrBytes));
    r := TBigInteger.Create(1, aBytes, 0, 16); //<== fixed
    s := TBigInteger.Create(TConverters.ConvertBytesToHexString(aBytes, False), 16);

    Assert(r.Equals(s), 'BigIntegers are not equal');
  end;
