DIY Battery question

Just checking really…

I’ve got into battery building - Li Ion, 21700s, 4000mah each.

Am I right in thinking that no matter whether its 2s, 4s or 6s, I can charge at 4amps? And 8amps if its 2 in parallel?

Just got a 21.5min flight with a 4s 21700 li Ion, and a 5inch quad - flying VERY casually!
