BATTERY PACKS

Tawaki designes high capacity battery pack, built to deliver high energy, without compromising power performances. The different chemistry, based on project’s need and their great flexibility allow to minimize the battery size and use Tawaki battery packs into a wide range of sectors and applications.
Battery Management System (BMS) and other custom designed electronics, guarantee thermal management, battery performance and safety.

Main Features

Product description

18650 lithium-ion battery packs are constructed by spot-welding 18650 cylindrical cells in serial or parallel. The resultant battery has high energy density and cycle life with low cost compared to other power options. Cylindrical cell formats also show high reliability compared to other format options.

This 64 x 18650 battery pack uses a different chemistry and producers cells in pack configuration. The resultant 8S8P li-ion pack has a 26800mAh 28.8V 18650 battery specification.

Please note that these specifications are assuming 3.6V per cell. Many manufacturers assume 3.7V per cell in order to inflate voltage and power ratings. This battery pack is equivalent to a 29.6V lithium ion battery pack.

The 8S8P battery pack specifications make it suitable for e-bikes, power tools, consumer electronics, and many other applications.

The battery uses high-quality cylindrical cells imported from important global producers, which have a high gravimetric energy density rating and a low maximum continuous current discharge rating compared to other cells.

Assembly and testing is performed in our facility in Promano, Italy. PCM/BMS, connectors, tabbing, pack shape and other requests can be accommodated.
