$24 for shipping a lipo!! Yikes! Do they wear a mask when the sell those?
You know they Do!
Steamer, that's just a "buck" control module, call it a higher end regulator. You'd still need some kind of DC supply to be able to use it.
Here's a Video on the way cheap unit, it takes a plug in the back power unit like a lot of other things. It looks like it will do the same thing as the more expensive ones, well probably not as well & not for as long, but Hey I dont need a really good one to revive the odd lipo once & a while
