KUGOO G1 АККУМУЛЯТОР 25 000 МИЛЛИАМПЕР | ДИАГНОСТИКА СТАРОЙ БАТАРЕИ ПОСЛЕ 4000 КМ

Today, we showed the manufacturing process of the battery for the Kugoo G1 electric scooter. We used high-current 21700 cells from the LG M50LT as the basis for the assembly. The assembly itself was performed on professional equipment and high-quality consumables. We also conducted diagnostics and defect analysis of the old battery, which had received complaints from the scooter owner. We'll continue with the repair in the next video. Enjoy!
