Збірка Lifepo4 акумуляторів 12V. Тестування бюджетних BMS. EVE C40 IFR40135

In this video, I assemble 12V Lifepo4 batteries based on EVE C40 IFR40135 (20Ah) elements. I assemble one battery by soldering, and the second I weld nickel-plated tires and compare the result in terms of resistance and heating. I test cheap BMS boards and batteries under load.
