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 red 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!

Best charger on the market
Wow. What a nice charger. I have around 80 electric planes and around 160 Lipo batteries of all types and sizes. This charger if fully programable and handles them all. Not only charges but will discharge and storage charge. I own five other Lipo chargers and have put them all away after getting the Graupner. Liked it so much I bought 3 more. A bit pricey but I feel worth the money.

First Class
Absolutely a top notch charger. Does it all in auto or manual modes. I am a tech junkie so I love the graphs and data so I am assured of what really happened. It is pricey, but worth the expenditure. I have been charging RC batteries for the last 20+ years. I wish I had had this one from the start. I have 10 battery profiles stored in each channel. I have 10 left for each channel. That covers every battery for every model I own. My previous charger would not discharge at a rate more than .60 amps. That is an eternity for a 5200 mah battery. I get excited every time I have the opportunity to use it. I know I'm only scratching the surface of what it is capable of doing. 5 Stars is just not enough.

Love It
OK, finally I got one that works and it does a great job. works great, the Bar graph and letters are bigger that on the Pro version. I love it with this charger, the Balance option and the Cycle I was able to revive some damaged Batteries (Don't worry I will use this for testing on the ground
