All looking good so far, still have the brakes to sort (get the vacuum assist working) and fuel gauge to fit along with cable extensions to make all the battery bank voltage test wires available from inside the car without the need to keep taking the soft-top rear part out (several screws) and removing the
engine J motor bay service
panels out to get to the bank sensor wires.
Each of my batt boxes has a circuit board for each series bank of 9 paralleled cell packs which breaks out the voltage sensory wires, in effect this means that I can sense the voltage on each individual cell string of 4 series banks in each box (12 banks in all to give me the 222v I need for the motor)
So when I plug my 20 quid battery voltage sensor widget it shows me 5 voltage readings, this is because I am using 5S cell packs, each cell pack having 5 actual cells in series, hence the 5S.
However as the voltage sensor boards are all connected in series across the box what I am actually sensing is the voltage of a single string of 4 cells, 1 for each series block.
So the first voltage reading on the widget reflects the voltage of cell 1 in block 1 + cell 1 in block 2 + cell 1 in block 3 + cell 1 in block 4, the second shows cell 2 in block 1 + cell 2 in block 2 etc.
