Hi Karan,

I don't believe we have anything that matches exactly what you are looking for, specifically a battery charger that can charge 48V or >10A.

You may want to look into the bq24650, which can support most of your usercase. You can follow the App note :http://www.ti.com/lit/an/slva437a/slva437a.pdf to modify the charger to support lead acid.

For higher currents, you can use two chargers in parallel.

Higher voltages are a little more challenging to achieve. Do do that, you have to modify the circuit to isolate the charger pins from the high voltage, and drive FET's capable of the higher power rating
