Graupner Polaron EX Combo 7S 3" Color and Touch TFT (Silver))

INCLUDES:Charge cables, balancing boards, power cord


The Graupner Polaron EX Combo charger is a dual 400W (total 800W) charger that can charge two batteries simultaneously. The supplied Polaron power supply conveniently attaches to the side of the Polaron EX providing a continuous 12V 24A power source providing a charge power of up to 220W per channel.

The Polaron EX uses an easy to use color and touch TFT LCD screen making operation and menu navigations easy. The charger will automatically setup the optimal charge profile after entering the battery type, cell numbers and battery capacity ensuring efficient and safe charging. Each charge channel can hold up to 20 different charge profiles eliminating the need to re-enter battery information. Just load the required battery profile and press charge. Charging is done safely with the supplied balancing boards where the batteries are constantly being monitored for optimal charge capacity. The supplied temperature sensors will add extra safety when charging batteries at a high charge rate. Batteries can be placed in store mode which will prolong the cycle-life when the batteries are not in use.

The modular design allows the use of the Polaron EX indoors as well as outdoors using an external 12V-24V power source. The supplied USB cable can be used to update the charger s software or with a desktop computer to monitor charging with our free monitoring software.
