I had been looking over my battery choices a couple months ago and recently wrapped up my electrified GoPed project and want get a new battery for it. So I started looking at batteries again.
Ok so the battery I’m not seeing much information on here is the Samsung INR18650-30Q. This is a 3000mah battery that can do 20a intermittent and 15a continuous, all for $3.18 a cell! Just like the 20R they only quote 250 cycles at that load but I hope I will get better using a lower rates. I also attached the data sheet.
So should I pull the trigger on 200 cells, I just wanted to make sure there wasn't a new giant battery scam going on that my searches were not catching? My current project is only for 56 cells but will be assembling a new bike after selling my electric motoped that should fund a project for the remaining 140 or so cells.
