ISDT K4 Lipo Battery Balance Charger Discharger 1-8S AC 400W DC 600Wx2 Smart Charger for Life, Lilon, LiPo, LiHv/Pb/NiMH Battery

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.

One of the fastest A/C chargers I have ever used. It will charge a battery at 20A continuous and will do two batteries at 12.2A per channel which basically will change two 10,000mah batteries in 30min. Don't waste time and money on cheaper chargers you're just wasting time waiting an hour charging batteries that could be charged in minutes.

This is a good charger for most people's needs. It's well built and super easy to use and has a good amount of power. I must say I'm a little disappointed that you cannot parallel charge unless you have a DC power supply. And for my needs, I wish it had a little more current capability on the individual channels. You can only charge at 20 amps per channel regardless of using a big beefy power supply or not. And parallel charging using a big power supply. You will only get up to 35 amps charging a 2s battery pack. I race competitive stock racing at a very high level so this charger would really suit me much better if it would do at least 30 amps per channel. But alas, that is not the case so I will probably end up selling mine and moving to a different charger. And by parallel charging what I'm talking about is using both channels combined into one for a higher charge rate. I just feel for the money that this charger should have a little bit more power output. Other than that it's pretty nice.

Got mine today. works perfect, bluetooth works with ISD LINK app To connect the Bluetooth for the first time, phone has to be really close to the charger

This is BY FAR the best charger I've ever owned. I bought it to primarily charge 8s for my for freestyle quads and can't believe how fast and efficient this charger is. It even has a destroy mode for bad batteries. I plan on buying two more for my charging center. By all means spend the extra and buy this excellent piece of equipment.
