The battery is highly recommended to be used with the charger that comes within the package as they are compatible with each other. Can the lithium battery charger and lead acid battery charger be universal? No, please use the lithium battery charger. How long can your lithium battery last? The household life is 3-5 years. If it is not used for a long time, it needs to turn off the switch (2–3 months charge-discharge–cycle) and the life is 3 times that of lead acid. Charge the battery after receiving it, use the correct charger. After the product is stopped, the lithium battery should be charged in time. It must be charged by the battery charger. 24V is 29.4V; 36V is 24V: 48V is 54.6V; 60V is 67. 2V; 72V is 84V, etc. 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. There is a switch to prevent heavy pressure and child contact, and a full charge every 2 months. We will try our best to help you solve the problem. 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. 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. BMS can balance energy among batteries to make them more identical and expand its discharge cycle. 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.
