12v leisure battery's

[Jason A]

I am looking at buying a 12v leisure battery now the outdoor season is here for charging from.

There will be 3 people charging of one battery any ideas how long a 100amp plus battery should last before 12v battery needs charging

Cheers

I have a 120 that does me and my mate for a good days racing 4 quali and final easy and i dont always charge it.
Used to have a 120 for when i did tc and that had even more load on it tyre warmers etc,and did practice day and race day???

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.
