im new to electric cars and i just got a tamiya tt-01 should i store the battries flat or charged ?

i like to leave mine with a half charge and havent had any problems yet.

depends on the batterys u have nicad or nimh?
when i used nicads i run til almost dead then recharge helps the cycle better,doesnt matter much with nimh tho they have no memory lose issues
better to run then down then half and recharging then it will end up damaging the pack otherwise[]

I leave my IB4200 with a half charge on them.
