Charge multiple batteries simultaneously with the Graupner Polaron EX dual-charger, for a grand total of 800W.  The beautiful TFT LCD touchscreen gives the Polaron EX a user-friendly interface. Automatic setup provides optimal charge profiles, ensuring efficient and safe charging – simply enter the battery type, cell numbers and capacity information and the Polaron EX will do the rest!  Eliminate the need to re-enter battery information by using up to 20 different memory profiles – just select the appropriate battery profile and press CHARGE. Prolong the life-cycle of your batteries by discharging them and/or placing them in Store Mode when not in use.  Safe handling and monitoring is easy when the Polaron EX is attached to the supplied balancing boards and when used with the enclosed temperature sensors that carefully monitor high charge rate batteries.    

Personalize your look with the silver casing.  Stay informed on a desktop or laptop computer via the USB connection by monitoring the charging process or upgrading the firmware with our free Graupner Update Studio.  The Polaron EX excels at bringing new life to your batteries and hobby experience!


The Graupner Polaron Switching Power Supply has been specially designed with a genius side-docking power system that eliminates the need for external connecting cables, allowing a seamless coupling to the Polaron EX.  The user-friendly LCD screen keeps you informed of integral real-time information regarding consumed current, voltage, and charging environment temperature. 

Charge additional devices simultaneously with additional output connectors, and the frontal USB port provides plenty of power to charge your USB devices!  The Polaron Power Supply is the perfect staple for your hobby workshop.

Graupner Polaron Ex Combo Charger, Silver
This is a very nice charger/balancer. The features are outstanding and very useful. My batteries have been increasing in run time since I started using this wonderful piece of equipment. Quick delivery. Recommend highly. Thank you Graupner and Amazon.

Great Modern Duo Charger
What attracted me to this charger was its small footprint - it doesn't take up a lot of space on my workbench. I've had it several weeks and it seems to do everything well. It was very easy to learn to use. The touch screen icons are small but the included stylus helps with that. Overall, I'm very happy with my purchase!

What a nice power supply/charger combo! I bought one, used it for two weeks, and liked it so much that I bought a second one. Setting up the different profiles takes some patience (and the instructions are a little confusing for this process) but after you do it once, you are set and ready to charge, cycle, store, or discharge any battery type (LiPo's up to 7 cells on each channel). I found that charging two 6S, 6000mAh LiPo packs at 1C, one on each channel, just about pushes the power supply to its max capability. But not many of us use anything larger than 6000mAh 6S batteries. You can connect the charger to a 24V DC power source, but the supplied 110V power supply only provides 12V to the charger; it would be nice if the power supply could also supply 24V! After or during any of the programs, you can monitor input voltage, charging current, elapsed time, pack V, power supply temperature, pack temperature (two temp. probes are included), average cell V, high and low cell V, gap V, individual cell V, AND INTERNAL RESISTANCE OF EACH CELL! And I probably forgot to mention many more! Graupner also sells a well made and reasonably priced carrying case for the power supply/charger. Shipping is free, and I received mine two day after placing the order!
