Not sure if this is the right place to post this, but just wondering if anyone has tried the lifeline mod. Personally, it seems madly overpriced at $6,500 and then an extra $1,000 for an "auto-winch". I'm not sure if maybe I'm thinking too much but why not just buy a bunch of extra batteries with that? I'm sure you could purchase enough to get more than the advertised 2.5 extra hours and additionally, you don't have to be tethered. Anyways, I just want to know if anyone has tried it out and what was your experience.
