Let's say I have a device that presents a 5A load. Is there any advantage to using a 25r (20A maximum discharge rating) over a 26f (5.2A maximum discharge rating)? Would the 25r be able to hold a higher voltage under that 5A load, last longer (more usable amp hours), and/or have a greater cycle life since it is not worked as hard?
If there are advantages, do they still hold true under a 2.75A load, or do the advantages lower in magnitude?
The scenario is an ebike that presents a either a 22A or a 40A load to a pack that has 8 groups in parallel (14 in series for 51.8V). I'm trying to determine if it is worth paying more for a pack made with 25r cells vs 26f cells.

Yeah, if you are going to use 3 A per cell (which is great for cells), no need for buying high rate cells, buy cells like 29E or PF, they are very cheap and have more capacity. Or even something like 32E which costs similar but has almost 30% more capacity
