If the Tesla battery says 13.5 kwh what does that mean..you can use 13,500 watts or only 30% representing how much you can discharge your battery...I could never get a vendor to tell me exactly how many amp hours a tesla battery is good for..its a simple question you could think but I have not had a simple reply...could a vendor not say...its approx 2000 amp hours at 12 volts which means to discharge 30% or 50% or whatever is the discharge limit you have so many amps hours???
I do it this way..add up in watts daily use and divide by volts to give amp hours. ..if the bank is day 1000 amps and safe discharge is say 30% you know that your usage should not go past approx 330 amps.
How do you work out a) capacity of the tesla battery in amp hours at a particular voltage and b)what is its safe discharge rating.
