I have done some reading, and have not really found a good answer.
How would one be able to charge their cellphone/remote or other accessories directly from their battery (via. a standard 5Volt USB port)?
My understanding so far is to use a buck converter to drop the voltage down, but has anyone built something like this to charge their phone through their board? Has anyone done this either through the VESC or the Battery, and which would be better?
Any pics or relevant links to parts to buy would be awesome as to teach others like myself how to construct this kind of project into a board is definitely appreciated!
I have multiple buck converters on my board that runs lights, USB charging, wireless accessories. All you need is a buck converter that goes to 5v with an input voltage above your battery’s max charge. I built mine into the deck but you can also run a separate module and use the charge port on the deck as a power source etc.
Google the LM2596HV module. It’s very small. There are many sources for it including amazon. Idk where you live so idk which site is best to link you to. The LM2596HV is good up to 12s (50V) which should work with most boards, it is a variable voltage converter, it can be set to any voltage you wish, and 2A output. So for USB, set to 5V and you can charge or power anything to 2A. Alternatively you can set it to 12V and be able to power any car accessory.
Make sure it is the HV version (high voltage). There is also a regular LM2596 which I think is good up to 10S, same amp output.
By the way, that one also has mounting holes which are easy to overlook as a trivial detail — until you need to mount it in your enclosure. The other ones are a “wrap in fishpaper and packing foam and toss it in there” mounting style. Works, but
Here’s an example of one without mounting holes
This is a CC/CV one as well, the other is a CV
CC/CV = continuous current / continuous voltage
CV = continuous voltage
