That might be the best for me. Insulated battery box below the bus.
Mine will be a custom LI-ION pack built from cells used for electric cars. They are not harmed by freezing as long as the parameters are set correctly in the battery management system.
The cells I will use are available from 20 amp hours to over 1000 amp hours. It takes 4 cells per 12 volts in your system. For versatility, I may stay with 12 volts, but may go as high as 48 volts when I get the inverter hooked up.
They will be housed in one of the bays in the belly of the bus. I will use a large ABS pelican PELICAN Case, 33-3/8 InLx28-7/16 InWx18-1/4 InD - G4785523 at Zoro Canada
luggage box with wheels to hold my cells. The battery bank will be removable by simply disconnecting and removing the case.
This is for versatility. The battery bank will be able to be used in my electric car when I build it, as a silent generator on work sites, ect. It will also have the charger built into the box so I can charge it in the house, shop, or anywhere else I need to.
The battery cells.

The compartment will be insulated and heated with a heat loop from the hot water heating system. It will have it's own thermostat to keep the battery's from over heating.
