AOK Digital Battery Meter
- Product Review (submitted on June 25, 2013):
- This is one of the best $5 I have spent. I have been using it for about a year now. It quickly tells me the total pack voltage and individual voltage of each cell. Simply plug it into the JST-XH plug and it tells you the number of cells, the total pack voltage, followed by each individual cell voltage. Each voltage display has three significant digits. It is also reverse voltage protected, so if you plug it in backwards, or on the wrong pins (as I have done plenty of times) it won't turn on until you get it right! This tool definitely follows the KISS principle.
