Buy a used Tesla battery off Craigs' List and rebuild it as a 48 volt pack... rows of 16 cells in series, connected in parallel.
A programmable smart charger should be able to handle the charging (67 volts), pickup a BMS / balance board from batteryspace.com to keep the cells happy and the magic smoke inside where it belongs.
Something like this could work too:

Ten of those in parallel gives you over 7200 watt-hours of capacity, of which you can use all of it... none of this 50pct nonsense of lead acid batteries... all ten of them will barely take more space two lead acid battery.
