Re: Confirmation of SOC vs. Voltage Chart
Confirming that charging at a lower voltage (within reason) will still get the job done, albeit with the longer time trade off.
The chart that you posted Tom is correct, but what you have there is the settling voltage, not the max charging voltage. But it is also misleading in that a 100% charged pack will not stay at 58.4v for very long. It will almost instantly drop. The settling process will take time too. To get a accurate settling voltage you will need to wait 24 hours.
Your experience of replenishing 30aH with a 15A charger in 1.5 hours does not compute, no matter how you look at it. The only explanation is that your charger is able to supply greater than 15A or that your battery draw was less than 30aH. Does your SOC meter count up when charging? If so, are you able to monitor it whilst charging? Also, can you measure the open circuit voltage of your charger, that’s when it is turned on but not connected to the battery.
Cheers
Pat.
