18650 - Part 1 - Internal Resistance meter for 18650 battery cells

This is the first video of a series that will show the use of used 18650 cells from laptop and ebike batteries. They will be the backbone of a DIY Powerwall. This is actually a battery bank, made of single cells put in parallel and series to get the amperage and voltalge high enough to be efficient. Tesla Motors actually triggered this movement by their Tesla Powerwall. See how my system will come alive through the series.
