The Swit LB-SU98 2KIT with charger and dual batteries is an excellent, versatile choice for all those who need an easy and safe way to recharge their batteries and accumulators. The PC-U130B2 charger is a device with two battery inputs, one for charging and one for power supply, allowing two batteries to be charged at the same time. It is equipped with ‘smart’ technology that automatically monitors the charge status of the batteries and stops charging when they reach 100% capacity. The charger is also equipped with protection features against overcharging, overheating and short circuits. While the LB-SU98 twin batteries are two lithium-ion-polymer (Li-ion-Polymer) accumulators at 12V 7Ah each, which can be used separately or together as a pair.
