pF battery pack

6 cells in series, 2 in parallel

19.8V,  2.2 Ah nominal

yea…so there’s definitely a sacrifice of performance for aesthetics here, but the entire pack fits into the central tube! Makes me wish I used a larger diameter tube…

full battery pack assembled. Packs are probably rarely spec'd with a radius of curvature.
just the terminals will be sticking out. The 7pin white terminals are for load balancing.
Cells were soldered end to end with a piece of braid. A ribbon cable worked great for all the load balancing leads.
