Tester for 18650 batteries that can measure the capacity and internal resistance of the battery. It has a 1.77 inch color screen for displaying multiple information related to the tested cell and can charge and discharge the battery.
The displayed information is: Voltage, Current, Power, Capacity, Resistance.
The discharge current is up to 1A. The discharge is carried out through the two 10W resistors by heating them.
The module has two slots for 18650. The first is only for powering the module , the second is for testing the battery. Charging the test battery can only be done by connecting a charger with a USB Type-C plug to the dedicated port. To discharge the test battery, it is not necessary to use the USB port, but only an 18650 cell on the power slot.
There are two USB Type C ports on the module. One is used to provide the charging voltage when the battery is to be charged. The second one is used to download (it is linked to the test slot).
It has a physical ON/OFF button.
The module has no memory. Once the module is turned off or the operating mode is changed, the displayed values are reset.
The battery capacity is measured exclusively during discharge (battery capacity is measured only during discharge), the module not recording during charging but only during discharge.
The battery resistance is measured immediately after connecting the cell. This value is a reliable indicator for establishing the health status of a cell. This module is a hobby level one and the displayed resistance value is not very precise but it is enough to give us an idea about the state of a cell.
Depending on the batch, the discharge current can be set or not, the physical ON/OFF button not being present.
If the module arrives in Chinese, change to English by following these steps:
1 - Insert the battery into the power slot (Left).
2 - Switch the switch to the OFF position
3 - Hold down buttons 1 and 3 at the same time, switch to ON and release buttons 1 and 3
4 - If it does not work, remove the battery, wait 1 minute and try again

Multumit in general de serviciile firmei.Insa despre acest modul am o parere proasta.Functioneaza doar pt decarcarea(verificarea capacitatii de stocare)a acumulatorului 18650 dar pe functia de incarcare nu vrea deloc sa mearga.Am folosit si incarcator de 5V /1A si de 5V/1,5A si tot nu vrea sa incarce.Efectiv incepe incarcarea si se opreste(END)dupa 5 secunde.Iar pe mufa de TEST2 pt port extern de verificare/descarcare alta sursa(recte un power bank sau un alt acumulator)deasemenea nu functoneaza.
Cel mai bun mod de a verifica acumulatorii.Dispozitivul isi face treaba.
Funcsioneaza perfect si pe incarcare si pe descarcare. Am vazut comentari ca nu incarcaaaaa, setat corect si o baterie buna funcsioneaza fara probleme
Am vazut un post al unui cumparator Mandea Neculai. Nuincarca pentru ca usb-urile nu fac contact nici cel de la alimentare nici cel de la descarcare, Sunt defecte din nastere. Am conectat alimentarea direct pe placa de baza si este ok. Integratul care supravegheaza incarcarea respectiv TC4056 se alimenteaza din usb c DC 5v.
Aceasta problema am avut si eu cu acumulatorii recuperati din laptopuri si masini de gaurit,de vina erau acumulatorii,testerul cumparat functioneaza cel putin la mine foarte utila pt selectia acumulatorilor
