What is the worst-case scenario that can occur when using a third-party charger thats not specifically designed for a Shimano Steps E8000 battery, and can anyone provide empirical evidence to support the notion that the manufacturers warnings about using non-OEM chargers are more than just a thinly veiled attempt to strong-arm consumers into purchasing overpriced, branded accessories? Are we talking about a catastrophic failure of the battery management system, or merely a slight degradation in performance thats only noticeable to the most discerning riders? Furthermore, what about third-party accessories like cranksets and chainrings - are there any known compatibility issues that can cause problems with the E8000s torque-sensing capabilities, or is it a simple matter of plug-and-play? And lets not forget about the elephant in the room: what role, if any, do proprietary communication protocols like ANT+ and Bluetooth play in limiting the compatibility of third-party accessories with Shimanos e-bike systems?
