AKK 1S LiPo LiHV Battery Charge Board Micro JST 1.25 and JST-PH 2.0 2-6S Input LiPo Battery Drone Charger for Blade Inductrix Tiny Whoop

Seems to be smart for my 1s batts. Tidy, tiny, you do have to use a power supply if course. I use an old laptop PS i got an an estate sale for a $1.

Good purchase if you have 1s batteries and don't need super accurate charging. The voltages displayed are not accurate. They show larger voltages then the battery actually has. I've charged many batteries and almost without variation, my multi-meter will report .04 volts less then the charger.For example, 4.24 on charger measures 4.20 with multi-meter. 4.24 would be an overcharge when you have it set to regular (not high volt) but the battery is actually at 4.20. I don't remember this charger actually charging higher then 4.20 even if the display is showing 4.24, 4.21, 4.19, etc. Thats another quirk. It isn't consistent and mostly undercharges but I'm okay with that as long as it doesn't overcharge.Also, it doesn't come with a DC adapter. I dug one out of my junk drawer. Its only a 2A adapter, so I set the port to charge at 200ma (6 x .200 = 1.200 or 1.2A). I extend the life of my HV batteries by charging only to 4.2v and at 200ma. Low and slow and I should get the maximum # of charge cycles out of them.

Good little charger, charges 6 1s batteries in around an hour. I did notice that the final battery voltage after charging was around 4.24v instead of 4.20v, not sure if the voltage reading is inaccurate or the charger just charges the batteries to 4.24v.

I mucked around with the settings, on the higher amp charge for HV, it would undercharge, as some other reviewers stated, mine would barely make it up to 4.2v, if you set back the amp to the lower setting it would keep going for a little bit more.What I end up doing is bulk charging with this board, then top each battery off on my other chargers.

Comes with multiple dongles 4 but should come with 6 since that's how many ports there are, also I wish the where a couple more just connectors.i also think it should be cover because the power spices are all exposed, they could at least put a silicone over them. But over all great charger for small battery's, especially if you have kids rc cars.
