有冇人見過或用過呢隻野呀?
佢可以俾你睇到舊電既:
number of cells,
voltage of pack,
percentage of charge and individual cell voltages to .01 of a volt.
individual cell voltage to .001 of a volt.
If cell voltage is below 3.0 volts per cell or if cells are out of balance a warning message will flash on the LCD screen and a beep tone will be heard.
見佢賣$459.
