New kinds of lithium battery packs were recently added to our Bestgo Battery lineup and we are excited to explain the benefits of each of these battery breakthroughs. The three kinds of battery modules are:

          1.    Plastic Block Modules

          2.    Aluminum Block Modules

          3.    Cassette Sheet Modules

The Plastic Block Module

The plastic block modules have a light weight and small size, cells are well held and protected in an anti-frame plastic frame block with necessary foams for vibration absorption. On the top of the block here is a plastic unit with two metal sheets built in. Cell tabs will go through them and lay down for the laser welding to firmly attach to the metal sheets for parallel configuration; here are screw holes on metal sheets for busbar connections among modules. Every module has an independent plastic lid for isolation. After blocks are assembled with busbars and wires, the plastic lid can be installed for isolation and protection but will not disturb the busbar connections and wires.

The Aluminum Block Module

The aluminum block modules have more cells held in the case with different arrangements for series and parallel configurations, like 3S4P, 4S3P, 2S6P, 3S5P, 5S5P etc. We do laser welding for cell tabs, use busbars for further connection among modules. The aluminum case can hold many more cells in quantity and resist outside force damage, aluminum has a light weight and is helpful for heat passing. It acts similar to plastic block modules but can deal with many more cells, so good for big battery packs which need many more cells.

Below are some of examples for reference.
