Aluminum block battery modules
BAB110-N module, 12 pieces of 3.7V 37Ah cells inside,
1S12P, 2S6P, 3S4P, 4S3P, 6S2P config.
BAB74-N module, 8 pieces of 3.7V 37Ah cells inside,
1S8P, 2S4P, 4S2P, 4S1P config.
BAC110-N module, 14 pieces of 3.7V 32Ah cells inside,
1S14P, 1S13P, 1S12P, 2S6P, 3S4P, 4S3P, 6S2P config.
BAC74-N module, 8 pieces of 3.7V 32Ah cells inside,
1S8P, 2S4P, 4S2P, 4S1P config.
When use less cells with foams filled will reach less capacity.
Bestgo make aluminum block battery modules which can hold many cells in one case with different arrangement for series and parallel config, like 1S12P, 2S6P, 3S4P etc., 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 and lay down, to have laser welding on metal sheet bars for the parallel and series config. Among battery modules here are soft-link busbars with screws for further connection. We build aluminum case for battery modules, because it has light weight, nice shell protection towards outside force, and good heat conduction when cells are in some high charge and discharge conditions. Bestgo made patents on modules design, they are easy for assembly and reliable in configuration, it simplifies the 3D design of the battery package structure, and makes the assembly process in production easier and quality control more reliable.
Here are some examples of Bestgo aluminum block modules.
For example, if one module has model name of BAB110-N-2S6P, BAB110 means it has 110mm thickness, N means chemistry of Li-NCM, 2S6P means cells arrange is 2 in series and 6 in parallel config.
For Li-NCM chemistry,
BAB110-N Series, with Li-NCM 3.7V 37Ah cells, can hold up to 12 cells. (Can use 32Ah cells to build smaller Ah modules)
