"Hello, we're doing a voluntary recall on the iPV3 Charger because there might be issues with customers not knowing about battery safety. This is a voluntary recall on our part and Pioneer4You haven't officially done a recall yet. The new versions of the iPV3 have their charging port blocked so they will not be able to be charged using the port anymore. To use the charger you must "marry" the 2 batteries together. Basically use those same 2 batteries every time and do not swap out other batteries for them. Also you must rotate the batteries by putting them on opposite parts of each other. We recommend doing this every time you need to recharge. There has NOT been any incidents yet, but we wanted to take precautions so we did a voluntary recall on our part."
