1: the batts will need something to reduce the amp draw to them. Even if you hooked a 60A rectified xfmr to them, the batts will try to draw as if they were a near short. Heavy charging will hurt them quickly.

2: charging at a higher pulsed voltage will not kill your batts, but you need to use a timer as oilpan4 stated. I've charged 36V and 48V golf carts/ scrubbers/ pickers with this circuit. I watched it, but about 4hrs oon a timer would be good.

3: Alternatively, you could use a xfmr to drop to around 39VAC then rectify that to DC and have a trickle charger.
