Modulul poate testa acumulatorii de orice tip cu tensiune intre 1 si 15V.
Cu ajutorul unei sarcini rezistive (doua rezistente incluse in pachet) descarca acumulatorul contorizand capacitatea reala a acestuia mAh.
Alimentarea modulului se face doar prin mufa micro USB cu tensiunea de 5V.
Detecteaza automat tensiunea de descarcare sau se poate seta manual o anumita tensiune dorita. Display-ul va afisa in timpul operatiunii de descarcare tensiunea acumulatorului, curentul de descarcare si capacitatea consumata.
Atentie la polaritatea acumulatorului cand il conectati pe placa.

Testing:
7.5 Ohm Resistor (0.54A-0.41A)
Battery A: Discharge: 2695mAh. Recharge: 2689mAh.
Battery B: Discharge: 2708mAh. Recharge: 2620mAh.
3.75 Ohm Resistor (2x 7.5 ohm in parallel) (1.06A-0.81A)
Battery A: Discharge: 2633mAh. Recharge: 2621mAh.
Battery B: Discharge: 2661mAh. Recharge: 2702mAh.
Usage:
1. Testing battery need to be full charged first.
2. Testing battery's positive post connect to input "+", negative post connect to input"-", do not connect
reversely( instrument will be damaged while connect reversely with load)! And then connect load to positive post and negative post, instrument's micro USB connect with working power ( do not use USB of computer or laptop to power supply), instrument display battery's voltage in this moment.
3. Start testing only need to press the button of "ok" directly, instrument can set a suitable end voltage
automatically that based on battery full charged voltage, and it flashes 3 times before testing. If you need set the end voltage by yourself just only press "+" or "-" to revise while have battery voltage shown. End voltage display "P" first, resolution is 0.1V, press "ok" to start testing after setting is done.
4. Instrument starts testing will contact electrical switch of control load, data take turn to display discharging capacity, current discharge current (A) and battery voltage (V) in this process. Instrument cuts off switch of control load when battery reaches end set voltage, displaying data stay on capacity (A) and corresponding indicate light together fast flash, it is battery actual discharge capacity in this moment, press "ok" can stop flashing and let data stable display, press "ok" again can recover to the state of power-on, you can change battery to test next
Error code and meaning:
Err1: battery voltage higher than 15V
Err2: battery voltage lower than end setting voltage
Err3: battery can't bear load discharge current or circuitry has too large internal resistance
Err4: current too large (current more than 3.1A)
