48V batteries widely used in Hybrid vehicles

Due to more and more strict environment protection regulation, more and more vehicles equipped with 48V batteries.

Compared with 12V AGM battery start- stop technology, 48V battery hybrid system is environment friendly.

In 2016, A123 published 48V battery systems, and in 2017, A123 got 2.6million sets 48V battery orders from Shanghai GM. In the end of 2018, A123 supplied 48V batteries to 13 car factories.

Though vehicles have 48V batteries installed, 12V batteries are also needed.

There are more than 30 electric controllers and powered by 12V batteries, and even more sensors and pumps are powered by 12V batteries.

If 12V battery are removed from vehicles, then all system need to adapt to 48V system. It will be a massive and complicated jobs to be done, and might cause vehicles un-stable.


If vehicles' 12V battery dead, vehicles can't be started. Big trouble arise.

For business man, vehicles anchor means time delay, and time means money.

For women drivers, vehicles broke down means helpless, and it's dangerous.

Vehicles anchor also makes user’s losing face, it's un-accepted by high end users.


LILEAD Auto Starter can prevent vehicles broke down, prevent car fires caused by battery short circuit, to promote vehicles safety performance.
