I am a new member here, so I thought I’d say a quick hello to all.
Need some assistance with the following adc
ADS7828 Analog to Digital Converter 16-Channel 12-Bit with I2C Interface
Is it possible to use this board to measure the voltage of each cell in a 48v lithium battery bank(3.2v x 16) while they are connected in series?
I would recommend using two of this ADC:
The ADC inked above has isolated grounds so you can ground each battery separately using the inputs.
The board you’re looking at has a shared ground so there will be a ground difference of 45v between the first and last cells. This this will exceed the 0-5v limit of that sensor.
Basically if you isolate each starting voltage as the GND and input the voltage after the battery it will stay within the 0-10v limit of the linked ADC.
