Power supply voltage: DC4.5-6V (micro USB connector) Operating current: less than 70mA Discharge voltage: 1.00V-15.00V 0.01V resolution Termination voltage range: 0.5-11.0V Supported current: 3.000A 0.001A resolution Maximum voltage measurement error: 1% +- 0.02V Maximum current measurement error: 1.5% +- 0.008A Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above to achieve 10Ah XX.XX, and so on.
Error Codes Err1: Battery voltage is above 15v Err2: Battery voltage is lower than the termination voltage Err3: Battery can not afford to load or discharge current line too much resistance Err4: Over-current (current exceeds 3.1A) ã€€
Â This tester can be used with lithium ion or lead acid batteries. The resistor gets hot during operation! We have used these extensively when testing 18650, prismatic and pouch lithium ion cells, and suggest using a cooling fan if you are going to be testing a lot of cells in succession.
Â This includes two 7.5 ohm 5-watt resistor for up to 1000 mA (1 amp) discharge rate. You can add additional resistors to up the discharge rate up to 3 amps; please contact us prior to order if you need more.
Â This accepts a 5v input via micro USB connector. It can also be hard-wired by soldering to the '+' and '-' terminals on the underside of the board. Each board uses less than 70 mA current during operation, meaning that several can be connected to a single household 5v USB power outlet.
