Ремонт аккумулятора Samsung Jet 75, 90 VCA-SBT90

🔍 Chinese Samsung Jet 75/90: Inside the "Phantom" and Upgrade to Premium Level! 🚀 In this video, I disassemble a Chinese knockoff (or aftermarket replacement) battery for the Samsung Jet 75 / Jet 90 vacuum cleaner (model VCA-SBT90). What's hidden under the casing of these cheap "counterparts"? Spoiler: inside is usually the cheapest thing you can find. 🧐 But we don't just look at them—we upgrade them! We remove weak, no-name cells and install modern elements using Tabless technology. I'll explain how this will change the performance of your vacuum: ✅ Tabless is a blade-less technology that provides minimal internal resistance. For a vacuum cleaner, this means: • Power doesn't drop at maximum (turbo) mode • Runtime is increased due to lower heat loss • The battery no longer cuts out under peak loads What was done: Opening the Chinese battery and analyzing the internals (comparison with the original Samsung battery) Removing weak cells Spot welding of new Tabless elements (I'll show you the process) Reinforcing the original BMS (control board) Testing the vacuum cleaner at maximum power – the result 🔥 💡 Conclusion: A cheap Chinese battery is an excellent replacement for the housing and BMS if you're willing to invest in good cells. You get reliability and power at a reasonable price! Have you encountered counterfeit batteries for household appliances?
