USB chargers for S headlamps
We are preparing for production our own USB 4.2V chargers for the S series of headlamps - S, S2X and S2RED. These are another test specimens, already nicely overmolded with plastics on our injection molding machine. The charger plugs into the USB port (virtually any) on one side and into the battery tube on the other side. The red LED lights up during charging and the green one when the battery is completely charged. They are charged with a standard CC / CV algorithm for charging Li-ion batteries with a charging current of 500mA.
