Watts Inside? - Greenworks 40v4ah Lithium battery pack opening #29282

It was a bad idea for this company to make their old batteries not compatible with the new line they have released. Either way it seems alot of tool suppliers are selling these off and they can be found for a reasonable price. Not many have opened these packs yet so i wasn't sure what to expect! After a little digging, i found 20x 18650 cells in a 10s2p configuration. I have yet to do a discharge test(fingers crossed), so stay tuned for more...
