The Bestgo Battery Li-NCM lithium battery pack aluminum
block modules have more 3.7V 37Ah cells held in the case with different
arrangements for series and parallel configurations, like 1S8P, 2S4P, 4S2P, 7S1P in one battery module. The top part of battery module is a plastic
frame with several metal sheet bars built in, the pouch cell tabs will go
through them to apply the laser welding for the parallel and series configuration.
Among the battery modules are soft-link busbars with screws for further
connection. We build the aluminum case for battery modules, because it has a
light weight, good shell protection towards outside force, and good heat
conduction when cells are in high charge and discharge conditions. Bestgo makes
battery modules with patents in design. Modules have a unified shape and nice
isolation considered to simplify the 3D design of the battery package structure
and makes the assembly process in production easier and quality control more
reliable.
