1. Small batteries in parallel are safer than using large batteries directly
2. The current passing capacity of small batteries in parallel is stronger than directly using large batteries
3. During use, the current between parallel batteries can be self-distributed
according to the capabilities of each battery to improve the overall performance of the system
4. The large battery formed by the parallel connection of small batteries is more uniform in terms
of relative current distribution and temperature, which makes the system life and reliability higher
5. Convenient production and processing: Several specifications of small-capacity batteries can be produced,
which can be paralleled into different capacities according to requirements
6. The design is reasonable, and a single battery can be maintained and replaced, reducing maintenance costs
