I love it. - I've been an RC enthusiast since the late 1970s. So as you can imagine I have owned a lot of battery chargers. This one is the best I've ever owned. It's powerful, easy to operate, reliable and it can do lots of things. I like that it can do up to 8s lipo packs. Also it has a "destroy" feature for old lipo packs, and it has protections so it would be difficult to accidentally destroy good packs that you don't want to destroy. now for the cons. I wish the usb charger would put out more power. It is a weak usb charger in my opinion. Also, I wish it had an on-off switch so I wouldn't have to unplug it to turn it off. Also, its power output is through xt60 connectors. I wish it had banana plug outputs since that is what all my other charge cables fit. So, there things about it that could be better, but over all, I think it is fantastic. Review: Highly recommended - Easy interface, powerful charger, acdc power makes it that much easier too!

Highly recommended ### ⭐⭐⭐⭐⭐ Great Charger for charging 2 x 4s 11000mAh simultaneously! *by K***R on May 7, 2022* Loving this charger so far. Able to charge 2 of our Gens Ace 4s 11000mAh batteries simultaneously at 1C, on the AC power source, no problem. Discharging/storage mode works well enough too. I don't really care about the lack of Bluetooth connectivity because I am using the ISDT BattAir Plugin dongles for each battery. So far, so good on those too. Instead of using the box it came with for protective storage, I found a case that works really well.
