The Challenge

The pocket light is a newly developed lamp by Rollei specially designed for photography or online celebrity live broadcasts. Because the internal space of the lamp is limited, the original working time was less than 4 hours. Considering that the photography or live broadcast process takes a long time, Rollei contacted Ufine Battery and needed to customize a lithium battery that is small in size, has a long battery life, is safe and stable, and can charge quickly.

Finding A Solution

Based on Rollei’s requirements, Ufine carefully studied analyzed, and designed a battery solution tailored for the customer.

1. Customize the size according to the limited space inside the lamp, and cleverly use the battery outlet method to design. Make reasonable use of all the internal space of the product, increasing the space utilization rate by 20%.

2. Adopting a high-capacity density solution and using the 811 high-capacity system, the overall battery energy density reaches 550Wh/L. Coupled with the full utilization of the battery size, the capacity of the new battery is increased by 50% based on the previous one. The battery’s operating time reaches Rollei’s requirement of 5 hours.

3. To increase the charging speed of the battery, Ufine’s battery engineers improved the internal structure of the battery and used multi-pole methods to reduce the internal resistance of the battery, improve the fast charging capability of the battery, and reduce the constant voltage charging time of the battery. This makes lithium batteries The charging speed has been reduced from more than 3 hours to a full charge in 1 hour.
