This capacity meter is of good quality, the quality of the card is of the best, as well as its components, works as expected. Only one filter is missing for the display, it lights up to the maximum and annoys the view a little, as well as the LED that indicates the 3 data (Ah, A, and V) that is to the right of the display.

Este medidor de capacidad es de buena calidad, la calidad de la tarjeta es de lo mejor, así como sus componentes, funciona como se esperaba. Sólo faltaría un filtro para el display, se ilumina al máximo y molesta un poco a la vista, así como el led que indica los 3 datos (Ah, A, y V) que se encuentra a la derecha del display.

I purchased the XB2L3 to check Li-ion cell capacity and discharge Li-ion cells to a set voltage for storage. Using one of the 7 ohm 5 watt rated resistors gives a discharge rate of just over .5 amps. Running in default mode aka down to 3 volts the capacity reads about 140 mAh less than my Xtar VP4 Plus reports. This is using the same 3400 mAh fully charged cell each time. The Xtar reports 3340 mAh and the ZB2L3 reports 3197 mAh. Which is correct? Close enough for me. The discharge to a set voltage for storage works well just set the voltage and hit OK. The discharge stops when the set voltage is reached. If the battery is removed immediately when the discharge completes the voltage will rise slightly after a period of rest so keep this in mind, less than .1 volts in my testing. If you leave the battery on the ZB2L3 longer it will start discharging again when the voltage rises. This is a great low cost way to test and ready Li-ion batteries for storage and you can't beat the price. Just add a Battery test rack like in the link below or similar, some wire, a USB power source and a Micro USB cable and you are all set. https://www.banggood.com/Four-Wire-Battery-Test-Rack-Battery-Clamp-10A-With-Terminal-26650-18650-AA-AAA-p-1310582.html?rmmds=myorder&cur_warehouse=CN

Works as advertised. The ZB2L3 does seem to read the battery voltage about 2 or 3 tenths of a volt lower (0.2 to 0.3 volt) than the actual value but this does not seem to be a problem for the type of comparison testing I'm conducting. For a very cost effective battery capacity meter this one works quite nicely and yields a fairly good idea as to the health/capacity of a given battery. I would not recommend this tester be used to test 12 volt gel-cell, "deep-cycle" or automobile battery's. Much good information on the ZB2L3 can be found on youtube.
