I mean a correct battery charging circuit. Unless I'm mistaken about BCR2's (which are somewhat new to me) ... if they're anything like capacitors and batteries... when they're fully discharged and you first start charging them, they will draw a lot of current initially. Allowing electrical storage devices to draw too much current initially creates excessive heat in it. Too much heat = damage.
Eventually though, as the charge increases (voltage across the BCR2) its current demand decreases.
I hope that makes sense.
