How to Choose Correct Charger Size

As discussed in a previous post, battery charger capacity is dependent on battery capacity or C-rate. If you have a battery bank of, say, 250Ah, theoretically you need a charger of 250A to charge your battery in an hour. But such a huge current would literally melt your battery after a couple of cycles because of the heat generated.
