Are there any specific recommendations for charging the battery in cold weather conditions, particularly when it comes to lithium-ion batteries often used in e-bikes and other cycling electronics, and do different manufacturers have varying guidelines for charging in temperatures below freezing, or is there a universal approach to follow, and how do factors such as charging speed and storage affect battery health in cold weather, considering some riders may need to charge their batteries in unheated garages or sheds, and are there any potential risks or safety concerns to be aware of when charging in cold temperatures, such as reduced charging efficiency or increased risk of overheating, and are there any best practices for storing batteries in cold weather to maintain their overall health and longevity, particularly for riders who may not use their e-bikes for extended periods during the winter months?
