Here’s my question, How does the service battery recharges? In a petrol car the 12V is used for the starting motor to turn the inertia wheel while igniting for the first time, then after the alternator recharges the 12V while the engine is running.
My thinking is a similar way, the 12V battery is used to run the SCR to connect the power battery, while the power battery 57V is running it recharges the 12 V, on it on while the batteries last. Am I thinking it the right way?
This is my issue, I connected a fancy equalizer, this equalizer drags a little bit of current while it’s turned off to keep the memory going . This little bit of current drags my 12 V . Since this happens once every 36 hrs I think if I turn on the key switch daily it will recharge the 12V while the key is on.
My solution, I’m thinking to install in parallel a huge audio capaitor to store the energy while the key swith is off, however from what I’ve seen 6 farads is not enough, neither 21 farads, I’m looking for bigger capacitor however I’m hesitating, maybe my way of thinking is not so right, can you both give me your comments?
