Keep all your GripBAT batteries charged with the PD Hybrid Dual Charger from Kinefinity. The charger allows you to charge two GripBAT 2S L-series batteries, two GripBAT 4S BP-U30 batteries, or one of each simultaneously, even though they are different battery types.
The charger also allows you to charge the batteries using PD fast charge with the optional 65W PD power adapter. The charger is powered using a separately available USB Type-C charge cable or adapter that supports 60W and above PD charging, and the Kinefinity 65W PD Power Adapter is recommended.
