Batteries recognized by delivery drivers as the most efficient: graphene batteries and lithium-ion batteries for cars.
1. Graphene Battery
Graphene batteries, like lead-acid batteries, are made of graphite, which can reduce internal resistance, improve conductivity and increase capacity. The main products are 60V24Ah, 60V32ah, 72V23ah and 72V35ah. High-quality graphite batteries can be reused 700 to 1,000 times.
The reason is obvious. A 72V35Ah graphene battery can reach 200 km on a single charge, while a courier can travel 100 km per day, 2 days and 2 weeks, and can absorb 170 times a year, while the battery life cycle is 1000 times, that is, after 5 years and 8 years, the battery life will reach 5.8 years. Of course, this is done provided there is no power outage and normal operation.
2. Automotive lithium-ion
The so-called "automotive use" refers to one cycle, which takes about 1,500 cycles. Lithium iron phosphate is the flagship product. Low-speed electric vehicles use aluminum casings, plastic casings or 60V 32Ah cylindrical electric cores. Choose an automobile lithium-ion battery with power of 60V32Ah or above, such as 72V32Ah, 60V50Ah (3Wh), and travel 200 km. Fifteen hundred cycles, if it's one every two days, it can be used 160 times a year and a set of batteries will last over nine years.
Precautions for charging battery cars
1. Do not place the car battery charger in a damp place, otherwise the charger will be damaged. If you do not use it for a long time, it is best to remove the battery and store it. Because batteries are prone to aging in the surroundinglow temperature and prone to explosions and fires in high temperature environments.
2. Do not use high-power electrical appliances (such as air conditioners, electric stoves, etc.) for a long time when charging the car battery to avoid overloading the circuit and causing a fire; plug in or unplug the charger plug with wet hands to avoid the risk of electric shock; also be careful not to let children touch or use power switches, outlets, and other equipment; do not charge near flammable objects.
3. Battery vehicles and electric vehicles should be stored separately and avoid direct sunlight and exposure; Battery life is usually 2-3 years, so it is recommended to replace the battery with a new one. or performmaintenance work regularly (generally at each check once every six months) taking care to prevent electrolyte from seeping into the electric vehicle and causing short circuit failure;
