I am building an e-board with a 10S5P Li-ion battery (15000mAh).
- 50A BMS
- 190kv 6355 motor from DIY, single drive
I was wondering how I could add a USB port for charging my phone. I was told I would need a converter (buck converter?) to bring the voltage down from 36V to 5V but I am unsure where to go from here.
