I have a question about charging the battery.
When to charge the acid battery properly.
I ask because I have a charging station next to my workplace and I can turn on the motor to charge while I'm at work, but when the battery is exhausted it takes about 7 hours to fully charge. The question is, if it is exhausted at 50%, will it turn on to charge and will it be a problem for the battery if it does not charge at 100% and reaches 90% for example?
My other question is when is a 72 volt battery completely depleted? When without load the voltage is 72 volts or less?
I have a wattmeter attached to the battery.
When the battery was exhausted, I reset the wattmeter.
After full charging indicates that I have 1500 watts of current available. As I start to drive the motor, the watts gradually decrease.
Now the voltage is 72 volts and I still have about 500 watts left and the battery indicates that it has about 30% capacity remaining, but when I deliver full power the voltage drops to 65 volts. This, in my opinion, is a very exhausted battery, because the traction is very low. The controller is set to 45 amps and when the battery is charged I have this power, but when I apply full thrust at the above values the battery voltage becomes 64 volts and it does not give more than 35 amps because it does not reach amps.
My point is: can I charge the battery whenever I want and as long as I want or always need to drain and then charge to the end.
