waiting for the rest of parts
for now working on batery monitor
we need to know if batteries are leveled so me measure each batery and use an 10 led bargraph to indicate its state
10 identical 12V bargraph voltmetters based on lm3914
bargraphs are easy to read when driving !
we have an digital volmetter to measure battery pack voltage (whole pack)
and this bargraph to measure the remaing power for each battery
we have chosen 10 leds bargraph (DC10GWA) with last 3 red to know when the batery is nearly deplition (11.2V) so that we will not destroy the battery
also voltage levels can be ajusted individualy
for separation we have used quadruple optocuplers (3 of them) to be shure that high voltage can not break anything
this can be mounted on secondary radio bay or in our case in the center on console (where were old warning lights for preasure,etc...)
cost for the whole 10 voltmetters is around 20USD
