100Ah will be more than enough.
Recharging a Lipo takes about 2Ah (plus or minus a bit, it depends on the class, driver and track).
x5 races a day = 10Ah.
x3 drivers = 30Ah.
But actually that's only at 8.4V so it will take even less than that out of the 12V, but thats a good upper estimate as chargers aren't 100% efficient and use some power for fan/display/heat.
