Lectricity first before using. We serve you wholeheartedly. PCB board Protection:Over charge, over discharge, over load and short circuit. BMS board Protection:BMS is used to supervise battery by measure its voltage, temperature, current and SOC (State Of Charge), give out alarm under wrong circumstance, cut off electric power link in severe situation in order to protect battery and make its life longer. BMS can balance energy among batteries to make them more identical and expand its discharge cycle. The battery is not allowed to be close to the high temperature heat source. Avoid charging in direct sunlight. Must be charged with a dedicated lithium battery charger. There should be no metal objects falling into the battery interface to avoid short circuit. Do not place the battery in a damp place or in water. Do not disassemble or modify the battery. Do not apply external force to the battery or drop it at high altitude. When the battery is not in use, it should be fully charged and stored in a dry and cool place. And a full charge every 2 months. Stored in a sturdy aluminum casing, easy to transport;Modern Shape design, easy to install and remove. The lithium ion battery can be charged on the bike, or easily removed for storage or charging in your home, office, or on the go. That frees you from worrying about battery loss. Ride more easily and you can. Monitor the remaining power. At any time, to determine the distance you can continue driving. After placing the fully charged lithium-ion battery pack for two months, its capacity is greater than or equal to. Ordinary lead-acid batteries are placed for two months, only 40%-50% of the nominal capacity. High quality aluminum components for universal mounting and. Built to the highest international standards. Approved and PCB protection:Over charge, over discharge, over load and short circuit. Low-self discharge, less than 3% per month;Low temperature effect, can work (discharge) in -2060? . Stable performance, built-in over-voltage, over-current, overload. Short-circuit protection, temperature protection, battery balancing, power protection. Do not remember half the charge is not a problem, the battery charge-discharge cycle life, life expectancy of up to 16 years. The Battery equipped with. BMS is used to supervise battery by measure its voltage, temperature, current and SOC (State Of Charge), give out alarm under wrong circumstance, cut off electric power link in severe situation in order to protect battery and make its life lo. The lithium battery is non-toxic and non-odor that is safe to use. Compared with ordinary lead-acid batteries, which have a large amount of heavy metal lead which is harmful to the human body and the environment, lithium-ion batteries are highly environmentally friendly products. Suitable for a variety of bikes, such as road bikes, e-bikes, DIY is the essential equipment. We will provide.
