BatteryOS seems to be the most important aspect here. Consumer electronics manufacturers have different goals than this class of product, which may not always align with every consumer. So if they are abstracting all that logic into their own MCU OS, that is pretty smart. I can see an iPhone/Mac app to tune your BatteryBox to charge faster at the cost of life time/cycles(?) (clearly telling you this!) or vice versa...allowing you to tailor the solution to your needs. This is different to what Apple would offer as they need to find a one size fits all solution and that is usually some sweet spot for high cycle count + low charge time and long battery life.

Going one step further, possibility for some ML to learn your use case and charge your MacBook accordingly. Regardless, the battery is irrelevant, the OS is key.
