I'm rebuilding a battery pack for my ebike. It's a 750W hub motor, and typically cruise at 300-400W, occasionally using 700-800W to overtake/accelerate.
My current battery is from Luna - it's a 13s4p 18650 48V battery with Panasonic GA cells (10A).
I'm DIYing a replacement and looks like 21700 is the way to go now. Availability-wise, I can't find much except Samsung 50E and Molicel 42A (in the US). Is 50E a reasonable cell for my usecase? My math suggests that I'm mostly drawing 1-2A (200-400W), occasionally hitting 5A and never really beyond. The 5000 mAh is also nice to have over the 42A. Thoughts?
Thanks!
EDIT: It seems that that isn't in stock either. The only 21700 cell around $5 that seems to be in stock is the 42A - anyone knows what's going on?
