There are four large manufacturers of lithium-ion batteriesworldwide: Sony, Panasonic, Samsung and LG. These Japanese and Korean manufacturers offer a high degree of production automation, whereby the cells produced have a very high quality. This is especially noticeable in terms of the consistency of the cells throughout all batches.
We recommend only to use cells from these four large manufacturers. The often cheaper cells from other manufacturers do not meet the requirements for professional medical and industrialapplications in terms of safety, consistency and long-term stability.
