The compact (0.4″ × 0.5″) D24V6F3 switching step-down (or buck) voltage regulator takes an input voltage between 4.8 V and 42 V and efficiently reduces it to 3.3 V while allowing for a maximum output current of 600 mA.
Roboteq’s SDC2130 (30V)/SDC2150 (50V) controller is designed to convert commands received from an RC radio, Analog Joystick, wireless modem, PC (RS232 or USB) or microcomputer into high voltage and high current output for driving one or two DC motors.
We sell a wide variety of batteries and battery packs from single AA batteries to 24V (20 Cell) 10000mAHr batteries. We carry NiMH (they do not have the memory issues common with NiCad battery packs). We also carry Sealed Lead Acid (SLA) batteries, LiFePO4 K2 Batteries, and Li-Ion Battery packs.
Of course we sell transformers to charge your batteries along with a automatic battery tenders that will monitor your batteries charging progress and stop charging when the battery reaches peak voltage. For chargers and transformers, follow this link.
