From Fantom Racing:
Plug this unit into your iCharger 308 DUO, 406 DUO, or 4010 DUO and increase its discharge capability up to 40 amps! Experienced racers know that warming LiPo/LiHV batteries increases their performance, by lowering the internal resistance. Lower internal resistance equals maximum power delivery to your motor! Warming your battery is easy with the iMAX40D! Simply fully discharge your battery, followed immediately by recharging it right before you’re ready to race. You will notice an immediate performance increase with your battery!
Specs and Features:
- Rated at 24 Volts / 500 Watts
- Built with ceramic thermistors for superior energy (as heat) dissapation compared with typical power resistors used by other available dischargers.
- 120mm cooling fan is thermostatically controlled and powered independentally by your 12V DC power supply. The fan will power on and off as needed to keep your iMAX40D at a safe temperature, and to keep the thermistors working efficiently.
- Works with iCharger models 308, 406, and 4010 (does not work with the X6 iCharger)
- Increases the discharge capability of your iCharger up to 40 amps!
- Works with any number of cells (up to 500 watts max)
- 33cm (13 inch) power supply leads
- 25.4cm (10 inch) discharge port leads
- 4mm high-quality bullet connectors, fit directly into all iCharger models and popular 12V DC power supplies
- Protective sleeve over wires
- Perfect for warming up batteries, which helps improve voltage and lowers internal resistance, for noticeable increased on-track performance
- Dimensions: 127mm (5″) x 140mm (5.5″) x 66mm (2.6″)
