I think it's got a use case for the speed-run guys: single connector, basically a SUPER-BEC you can just add on and leave permanently somewhere in the car. (I ordered some 12V/5A ones, that's a TON of server fans) wont work for everyone, but it may be a good alternative! also: will let you run 12V fans off anything 4S and aboveI like the idea, but to me it just seems like extra clutter inside the car and kind of unnecessary as I can accomplish the same thing off the balance leads of one of my main battery packs with a simple adapter. I know balance leads are only rated for 2A but I run two fans with a combined amp draw of 3.5-4A off of one without issue. I have a 3-way switch located in my right rear wheel well for easy access that allows me to switch between 2S and 3S operation. This is more than enough for my needs as I just don't have any big load items at present and I don't see any coming up in the foreseeable future.
