Before buying a lithium battery, check whether the battery used is a product. The quality of a battery depends on its quality, such as capacity and energy density. Secondly, find a lithium battery produced by a big factory. The production technology is mature and the after-sales service is guaranteed. The market reference price of lithium battery is 1250 yuan/kw h. If you need to run a long distance, you'd better install a range extender. With it, you are not afraid of running out of electricity halfway, and it can also help you ride without worry.
Because the cruising range of low-speed electric four-wheeled vehicles is still limited, it can not fully meet the daily travel needs of the public. If you want to increase its cruising range, you can install a range extender to increase its cruising range, increase its range of activities, meet the daily travel needs of the public, realize the freedom of traveling back and forth, and no longer struggle because of power failure in the middle.
The range extender can be purchased directly from the manufacturer and delivered directly by the manufacturer, which will be cheaper. We must choose the range extender produced by big manufacturers and brands, and we must have all-round guarantee of quality, performance, technology and after-sales. Otherwise, if it is a small workshop-style manufacturer, it will easily break down and there will be no guarantee in all aspects.
Suggestions for using range extender:
It is not recommended to start the range extender when the battery is full, but it is generally recommended to start it when the battery is only 30%-40%. Starting when the battery is fully charged has no particularly good effect. For environmental protection, it is recommended to start the range extender when necessary. Battery pollution is more serious than waste gas pollution. Protecting the battery means protecting the environment. It is not recommended to use the range extender when the battery is dead. When the range extender is started, it is electrically started. The battery is dead, so it may not catch fire.
