Tester cu 4 canale pentru acumulatori Litiu-Ion 18650 / Prezentare si testare kit de pe Aliexpress

✔️Hello! In today's video I presented the electronic part and tested a module for charging and discharging lithium-ion 18650 batteries. This kit bought from Aliexpress was able to test the capacity, energy and internal resistance of the batteries. In the clip, as you can see, I used INR18650-35E and NCR18650GA batteries. ✔️You can find the module purchased on Aliexpress here: https://vi.aliexpress.com/item/100500... ✔️For other similar clips, access the links below: ►Presentation and testing of lithium ion battery charger with TP4056:    • Prezentare si testare incarcator acumulato...   ►What happens if you connect lithium-ion batteries with different capacities in parallel:    • Ce se intampla daca legi in paralel acumul...   ►Do not confuse the capacity with the intensity of the electric current in the case of a battery:    • Nu incurcati capacitatea cu intensitatea c...   ►We measure the capacity and how we calculate the electrical energy of some lithium-ion batteries:    • Masuram capacitatea si cum calculam energi...   ►How I got the hang of NCR18650GA batteries bought from Aliexpress:    • Cum am luat țeapă cu 6 acumulatori NCR1865...   ✔️Content 00:00 - Introduction 00:31 - Presentation of the electronic part (teardown) 03:16 - Display menu presentation 08:56 - Accuracy of voltage and current 12:00 - Internal resistance testing on each channel 13:05 - Full charged maximum voltage testing 14:02 - Testing minimum voltage of 2.5V during discharge 15:32 - AUTO mode check 17:00 - Conclusions 17:57 - Finished
