Amp hr capacity multiply by the voltage of the pack gives me the watt hrs of the pack.
That tells me how many watt hours a given pack has.
Now if the pack was drained completely I would need to put back in that amount of wattage correct? So if I have a 36 volt 23ah pack I need to put back in 823 watt hrs of juice right? Now how do I calculate how long it would take to put back 823 watt hrs?
