Thanks for all the great advice available on the site. I am finally showing some progress onmy small Project: Solar andPowerwall for camping and emergency backup power

Setup:
*13S8P configuration using new LG MJ1 3500 mAh 18650 battery cells to connected via spot welding using with pure nickel strips
48V 13s BMS charging current 15Amps and discharge current 30Amps
DROK MPPT Solar Panel Battery Charge Controller
48v to 110v Inverter (not yet purchased)
UPDATE: I have 40 cells but will obtain the rest as holiday gifts. I can not wait to use the solar panel to charge the battery pack. I still have much to learn but thanks to this site and others I am learning as quickly as possible. Thanks for any suggestions regarding this project. Feedback is welcome.
 
Have you built it yet? If not, rearrange the cells for 14s as 13s is a bit low for 48V!
