@mk30 Direct DC charging an open tech battery can be done, directly from the panel, even integrated to a trike/cargo bike, but proprietary batteries like shimano and bosch have secret protocols to ensure you only use the official charger, beyond just proprietary plugs. 🙄 Maybe one day long after the corps figure out regen braking monetization, they'll sell you a regulated DC input device that could directly plug a... no, capitalism says it will be a proprietary panel.
