Hello, i have a battery bank composed of 6 12v200ah lifepo4 batteries wired 3series/3parallel. The system has gone dead and ive had to recharge with gas generator, ive been disconnecting the batteries and charging them each separately. Is there an easier way? I thought maybe if i connected the charger directly to the bus bar where the batteries come together it would charge all of them but im worried it will mess up my charge controller and my inverter. Any suggestions much appreciated. We dont have any sun up here for the next few days so im going to need to charge them soon. Thanks.
