There is a lot of batteries other than just the size. There is a big difference between cheap and expensive batteries.
One of the most important aspects is C rate. Roughly if you have a 10v battery, and it can do 10 amps it’s a 1C if a 10V battery (pack) can do 50amps, it’s a 5 C battery.
Big difference in performance and life span if you are pushing the batteries any where near the limit. You probably want a capacity twice what you need – as getting near capacity is going to shorten its life, cause performance issues, and generate heat (bad).
I tend to do the research and get a high capacity Panasonic or Samsung battery. I need the high capacity, because I tend to use small battery packs, and need the higher C rate. Luna (last time I looked) tends to use pretty good batteries.
