I've just connected up my CA and wanted to check how the Ah reading works. According to the manual it says it shows how many Ah you've used since the CA was reset.
My battery pack is 16 x 3.2V 30Ah cells = 51.2V 30Ah = 1,536Wh
Does the CA take into account the voltage of the battery pack in working out how many Ah you've used? Do I just make sure the Ah reading on the CA doesn't get to 30?
Also I've got the high current model which uses an external shunt resistor. This is connected between the controller and the negative terminal of the battery pack. After some initial testing, the Vmin read 15V which seems very low. Is this an accurate reading of battery pack sag or could this be the controller acting like a transformer and stepping down the voltage when the motor RPM is low? I'm using an Alltrax controller.
