Safety battery packs depend on reliable monomer cells, GMB

focuses on producing one size only:

GM93133200, 9.3*133*200(mm)

Thousands and thousands of production

repeating on this GMB93133200 only, so as to ensure reliability in quality and consistency in impedance, voltage, and capacity.



Then use a specially designed plastic frame to prevent possible short-circuit from one cell to the another:

With a smart BMS, over-charge/discharge can be prevented, and real-time monitoring of the voltage of each battery in a pack can be provided:  the safety of the battery pack can be double-ensured.

However, if both safety and more than 2000 cycle-life are required, LFP battery packs should be good solution.
