Automatic setup provides optimal charge profiles, ensuring efficient and safe charging â€â€œ simply enter the battery type, cell numbers and capacity information and the Polaron EX800 will do the rest!  Eliminate the need to re-enter battery information by using up to 20 different memory profiles â€â€œ 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 EX800 is attached to the supplied balancing boards and when used with the enclosed temperature sensors that carefully monitor high charge rate batteries.

Polaron EX 800W color charger
This is the second unit I have received from Graupner. The first one for what ever reasons failed. Graupner graciously warranted my old unit and replaced it with a new one. I have never had the experience before this to have a company honor a warranty basically with out questions. These units are the best that I have pleasure to own. I have a 4 port charger and the Graupner puts it to shame. These units are fast and accurate. You can test servos, center them and get endpoints. You can also test your motors, although I have not had the chance to test a motor. This is an excellent unit and I highly recommend getting one. Not cheap nor very expensive, and well worth the money. I really can't say enough good things about Graupner, their staff and service. Excellent

I have had a lot of chargers over the years and bought Polaron EX a few years ago. It immediately became my go to charger. I just bought another to replace my 4 port chargers with just this one. All the guys at my field are replacing their charges as well. A++ on this. You will love it
