I am a fairly new rider and so far I have used a 5S 8A Lipo.
Because of space saving reasons I want to make my own battery pack using Samsung INR18650-30Q batteries.
These if I am correct: https://www.nkon.nl/samsung-inr-18650-30q-3000mah.html
Is it as simple as buying 15 of them and then connect them in a 5x3 setup to achieve 5S 9A?
Also, I’d like to know more about battery management systems that allow me to simply charge by plugging a cable in, instead of removing my battery cover and charge the lipo with the power and balance leads with a ISDT charger.
Please advise me.
