Electronics-industry veteran since 1975 - James Post is an out-of-the-box thinker, creating innovative solutions for everyday problemsE-bike Batteries are dangerous when not protected against transients AND have no self-test – low-end Chinese battery management systems are the main culprits. E-bike Battery fires can become a thing of the past, but not spontaneously. Following a visit to China Cycle in Shanghai last month, it became apparent that low-end Chinese battery (management system) manufacturers were not inclined to incorporate this remedy into their designs voluntarily; even when it costs just a few dollars.The causes of the e-bike battery unsafetyIrresponsible manufacturers save by excluding essential safety components such as "Transient Voltage Suppressors" from battery management systems (BMS). The vast majority of e-bike batteries in China use low-end Chinese BMS without adequate transient protection and self-test, exacerbating the problem. That is, when one owns a possibly unsafe battery.
