  1. Hi, just been experimenting with a few ideas on battery charging. I have decided that a powered siding (12V dc) and pick up through the rails suits me best, an onboard buck charger output 8.4 volts to charge an EBL PP3 2cell li-ion battery, a boost circuit raises the voltage to 12v for loco control. I have replaced the loco on/off switch with a small latching relay TQ2-L-5V this is wired to isolate the battery if the rails supply is reversed, a blocking diode protects the buck charger circuit. So the loco is run onto the powered siding and starts to charge, I turn off
