There is no market for the assembly of electric vehicle batteries. Whoever does it will pay the price. Don't listen to those who sell assembly equipment who say that assembling batteries yourself is cheap. are all lies. To use an analogy, if you want to eat an egg, it's cheaper to raise an egg yourself than to buy one. In addition, after-sales service for batteries is very tedious.
First, convert it to units of energy: watt-hour = 48 volts * 12 amp-hours = 576 watt-hours. Last year, I bought 360 watt hours for 650 yuan. this year I estimate I can get it for 800 yuan. Size can be customized, monomer is 12 amp hours, 15 cells are connected in series, making 48 volts. When buying, ask clearly, do not use in parallel. Connection, use polymer and do not use lithium iron phosphate. Because theftume and the weight of lithium batteries are smaller than lead acid ones, so they can still be installed in place. On the other hand, lithium batteries are very light. you configure a lower capacity, you can still achieve the original battery life performance.
