Also depends how you have many batteries paralleled and the amp draw per cell, for instance a single Sony vtc6 cell might be ok for 30A draw for short times but

Also depends how you have many batteries paralleled and the amp draw per cell, for instance a single Sony vtc6 cell might be ok for 30A draw for short times but will heat up while doing it. And needs cooling/thermal dissipation solution. The lower amp draw per cell the less is lost to heat.
