You don't need any tools to make a battery pack using rc lipo. Simply plug the packs in series until you get the voltage you want. And they're a heck of a lot cheaper and many times more powerful than packs made with 18650 cells. My 10ah 24s pack (888wh) cost $180, $217 shipped in less than a week, took just a few minutes to assembly without a welder and I got over 15K miles and 4 years out the one I retired that still had ~90% capacity left in it. and it's rated for 200A, 300A burst.JTL said:
IMO, they're safer than 18650's by a long shot. Of course in the hands of an idiot, no battery is safe. Not even a common alkaline battery. Still, there are millions of children using rc lipo. And yes, I'd let my dad us them if he hadn't died in 1960. I use them and I've got 4 great grand children. I even use then in one of my 24V ups systems. And I'll never use SLA in them again as soon as the ones that came with them have to be replaced. Rc lipo gets a bad rap because they are abused so badly in the rc world, and people are just plain stupid. I wouldn't use 18650's for anything other than 18650 flashlights.999zip999 said:

There's a very big difference in build quality. Yeah, I'm old and running out of time too. I was very critical of EM3ev and their sales model, but having seen their updated battery building techniques and the cell separators, I'm eating crow, apologizing, and going back. After more than a half dozen BBSxx motors I'm about to become a MAC user too.JTL said:I don't fault em3ev and I made my purchase knowing the process, I only wish they were assembled in the USA to cut down the transit time and the high cost of shipping which is about 3x that of Luna Cycle. For those of you who criticize my impatience please know that at my age time is of the essence which is why I no longer purchase green bananas.

I just watched that video and was laughing... felt like bobcat goldthwait's Eastern European relative did the video or something...Tushar D said:
Power tool manufactures, electric car manufactures, electric bicycle manufactures, use 18650 batteries. Suspect that they have engineers that are very concerned with safety. Fire - not good!wesnewell said:
I have heard the same thing about LiPo.wesnewell said:
That's ridiculous. They ae much more stable than Lipo and ANY pack with damaged and carelessly handled cells can be a problem. Pack can be shipped if they are installed on a bike. Facts my friend! The Hoverboards I saw were cheap packs. NOT brand name grade A cells. Those pesky facts again!wesnewell said:
Um, that was the intent. Humor.addicted2climbing said:
