I've just finished a 48V 18650 13s15p cells battery pack from tumich rejected Bosch packs, I'm use to share things on the ES Facebook group (because is quickier and easier for me to answer and make questions) I've couldn't done the Job without tons of coffee and hours of reading this awesome forum, so I'm pretty greatful and an honor for me to share this low cost battery pack building with all of You. These are my 2 cents on battery building
