Thanks for the great feedback team.
@Aurum It’s going to be a lot of cells! Probably in a 12S configuration (12 in series). Each of these packs will have their own BMS system which will be in charge of balancing the pack. Charging and discharging is achieved by making sure your charger max output current is below the max charge current of your battery bank. Same but reverse applies to Discharge. I am still very open to design ideas!
@Svenska you are the best!!! PING PING PING
@Jabelone I will be finishing my esk8t and also building a small off grid system. 20% dead cells has been my experience as well and I am happy with 80% capacity 
so true @DistractionKitten! As such I will try my best to make a portion available to @dave and other HSBNE members when I work out my harvesting process. I know Buzz and Svenska have build some sweet riggs for this in the past
