I’m planning on building my own battery pack for my first board.
I had someone that was going to sell me some nice panasonic cells for cheap but it fell through.
What cells do you guys recommend now a days? The cheaper the better if there’s any good options. 
P42a and samsung 30Q’s are what i see the most
18650: p28a
21700: p42a, p45b, 50s
Depending on where you are, nkon is the shop to buy at i’m told.
At least if you’re in europe.
Yes stuff from Nkon gets to me in like 3 days and it’s the same for both shipping methods, also the instructions in All time discount codes can help take a few% off some nkon orders.
