I have published accumulator monitor (called LiXXX watchdog) one year ago. This design uses buzzer to signalize low voltage cell(s) of three cells LiPol / LiIon / LiFePo battery.
Now it’s the time for more sophisticated entrance. One possibility is using of JETI DUPLEX 2.4GHz system. It allows to transmitt data back to transmitter (TX module) and display them with JETIBOX. The idea to use this feature for monitoring state of battery cells is then obvious.
