You can buy battery warmers.

Do you NOT understand how much electrical energy it takes to heat up a thousand pounds of batteries from zero to 72 degrees?

Free lunch, MUCH?

They would never get cold with the insulation and small heater. To maintain a thousand pounds of batteries at say 70 degrees in a well insulated container would use almost no energy
