Foil Drive Max battery how to discharge it to iPhone or similar

Wing Foiling

Hi could be a silly question, but I would like to know if it is possible to discharge the foil drive max to a safe storage level by means of using the battery to charge another device?

Youll need to have a step down voltage converter. Im pretty sure foildrive uses xt60-xt90 connections.

So it should be something like this:
Battery → Voltage Converter (to 12V) → one of those 12v car sockets → plug 12v car usb adapter in and start charging your phone.

Simple:

Loads of other options. Just google 60v (this will be up to 60V) to 5V charger.

I use 120v incandescent light bulbs a few in parallel to discharge my efoil batteries they are dimmer at a lower voltage but it works it takes like a day for a large 2.2 kw/h battery and 3 100w bulbs.

I use this. Nice thing is you can set the final voltage and it auto stops.
