Its also accurate to point out that there are huge differences in design, construction, and safety protections across the range of batteries, e-bikes’ and chargers. And like many chicom-made products there is a general lack of quality control and configuration management, meaning there is no assurance that the components used tomorrow will be the same as those used today - especially in the cheaper no-name models. So like most technical topics posted here, understanding the actual truth requires more knowledge and information than is presented. And does not fit the black-and-white good-bad simplistic explanation FReepers seem to love.
Absolutely right. You don’t usualy hear about cellphones and laptops failing this way...and when it does, there’s a recall to fix it.
