ISDT K2 Air Lipo Battery Charger Discharger 2-6S AC 200W DC 500Wx2 20A Dual Channel Smart Charger for Life Lilon LiHv NiMH RC Battery Balance Charger - Bluetooth APP Control, LCD Display

Very good chargerEasy to navigate and understandEasy to chargeHas all the options for diff battery chemistries etc, different charge modes/storage mode/discharge/destroyForget about the Bluetooth!I live this charger and I use it in the house and take it when I go fly my quad, to field charge off a 100ah 12v lifepo4 battery with xt60 to ring terminals.A tad pricey but...BUY THIS CHARGER! HIGHLY RECOMMENDED!

I like how can be AC or DC supplied. App works well with it so do not have to sit on top of it while charging. have 2 of these and love the air tags so do have have to adjust charge rate from battery to battery. like how can see IR on the screen as well in app on phone.

Working great so far.

So far so good. The device did smell like it was around burning electronics when packaged. Other than that it works as intended. Fan only comes on when the internal temps go above 105 degress. Easy to operate.

The media could not be loaded. This is a good charger. However, the first two units I purchased from this seller were defective having something loose in the inside as can be heard in the video. The first charger had a small pice of plastic fall out of the fan vent.Do not purchase from this seller. I finally got one that was not defective from the ISDT Amazon store.

Used it now maybe a month. I don't see any internal resistance feature. It may be coded as something different and me not recognize it but dunno why it wouldnt show it as all other chargers. I also didn't like that it wouldn't charge a lipo under the NIMH mode. Yes I understand that a obvious do not do. But if you have a lipo that goes below it's operating voltage and won't charge or read all the cells. You can set the charger (any charge that will allow you to) on NIMH mode for 30 seconds or so under charge mode and then switch it back to lipo mode and 8 out of 10 times it'll charge it back up above the 3.20 volts per cell ultimately saving the battery pack from being thrown out. This charger won't allow that. But overall has plenty of power. Easy to use. Easy to see has a day and night mode, the type C port charges extremely fast so be careful to not let your phone or something overheat. But I like it anyway. Other than not letting me use the NiMh mode to recover any lipos from low voltage. I was very disappointed this unit doesn't have a on/off switch so must be kept on 24/7 or manually unplugged each use. I absolutely don't understand why make it and not have a on/off switch. I wouldnt have bought it if I knew that. But here we are.

The media could not be loaded. I enjoy this charger. Fits nicely in FPV bag. But after about 6 months of use (it sat on the same shelf) I put it in my FPV bag once. I never drop or throw my bag cause my quad is on the outside of the bag. I now go to use it and my buttons have fallen into the device. And the whole back plate has fallen off. It’s charged great. But the quality of what it’s made out of is not durable what so ever. Have a very rough time trying to contact manufacturer

This is a simply fantastic charger. Amazing wattage pumping out of an AC outlet. I double bang 2 6s 6000s in 30 minutes. wow.
