(Be sure to charge only batteries of the same voltage and cell count at the same time (2S with 2S, 3S with 3S, etc.). Connecting batteries of different cell counts to the Paraboard at the same time will result in immediate damage to your batteries and the Paraboard and may result in fire. Charging batteries of different capacities together (for example, one 11.1V 2200mAh battery and one 11.1V 5000mAh battery) is ok, but the voltage of all batteries must be the same)
looks like a fire waiting to happen to me
