Check if the bicycle's power indicator is normal, if it is normal, run it normally. If there is anything abnormal, please contact your electric bicycle dealer for technical resolution.4) Lithium Ion battery is environment-friendly and smart battery, and there is no "Memory Effect". So lithium ionbattery can be recharged at any SOC (stage of charge) without any damages to the battery. During the charging,plug-in the charger's charging port to the battery pack's charging port, and charging can be stopped when thecharger indicator turns to green.5) The optimum charging method of lithium ion battery is to recharge the battery pack at the time when the batterypack's capacity has not yet been discharged fully. In case the battery pack's capacity has been discharged 100%, the battery pack must be recharged within 48 hours, or else the battery pack may be permanently damaged because BMS system also comsumes electricity from battery pack which cause serious overdischarge to the battery pack.Product Description
