HELIFAR Balance Battery Chager, 1S LiPO/LiHV Battery for RC DC Adapter 6 Ports and JST Extension Cables Compatible with Micro/Micro JST 1.25/ JST-PH 2.0/ JST Plug (Black)

I recently bought the Mobula7 standard edition, which came with 4 lipo and a charger. That charger was crappy quality and caused lipos to die prematurely. So I began looking for chargers. At the time the UP-S6 1S LiPo Battery Charger was out of stock. It sales for a little cheaper, but is the same "rebranded" charger. This one, however, comes with a power adapter! They are identical in function.I love this charger. It can charge to 4.35HV, the charge current can be adjusted up to 1A, and it has AC/DC input so I can power it off lipo or power adapter. Lastly, it has a 5V output for USB accessories. So far this charger has been great! My only complaint is that it is a bit LOUD! The beeps can def be heard throughout the house late at night when everyone is sleep. Still worth it though!

Pros: Small, nice simple design.4 ports servicing 1S-2S. Rare 1S-2S only capable charger! (keep Whoops, Trashcans and Mobulas, etc.. flying!).Battery begins charging as soon as it's plugged in.Cons: All ports over-charge well beyond safe LiPo specs, or what you've set the charger for.Charger is grossly inaccurate when it comes to displayed voltage. Fully charged 4.20 pack will read as ~4v and try to charge!Limited to 1 charge current for all ports even though you can select LiPo, LiHV and other battery chemistries port-independent.Internal power supply runs very hot.Absolutely no advanced features like adjusting charge voltage/calibration, battery check, etc...Poor documentation.Battery begins charging as soon as it's plugged in. (I know I listed this one twice; it's a double-edged sword. I would like to have the option of when my battery starts charging.)Caveat: I may have simply gotten a bad charger as other people seem to like them; maybe nobody else has tested their battery voltages though... I would think twice as this is a pretty no-name brand and a very new company (website is only 1.25y old). I returned, did not replace with same. Purchased another Hitec charger. Will not gamble on a fire!I tossed brand new 2S batteries on to charge and the Port 1 battery completed just fine, but Port 2 charged for about how long I'd expect it to and then simply displayed 0V at me. It didn't indicate that the charge was finished. When I pulled the battery off the charger and put my cell tester on it, I found that it had charged my 2S LiPo, set correctly as a LiPo (not HV), beyond LiHV voltages. When I checked the battery that was in Port 1, which the charger said was sitting at an even 8.40v, was actually sitting at around 8.55! While one pack was damaged at being charged beyond 8.6v, I was able to salvage the others.I then tried a known good cell that I've flown a few times on (and didn't mind retiring) and experienced the same behavior. Every single one of this charger's ports charges too hot and does not display correct charge or cell voltage. This test cell was entirely ruined by the end of testing; massively bloated after being overcharged so many times.And speaking of heat, the internal 12v power supply gets HOT. Even with only 1amp of total charging, the casing of the charger gets very hot. No fan, either. By comparison my Hitec X4 Micro (only a 1S charger) can charge at a full 4 amps if I have 4 big batteries going or speed-charging, and the entire casing barely gets warm (no fan either).I verified charge voltages by using a known-good charger, a Hitec X2 AC Plus, as well as a hand-held voltage checker, as well as a multimeter (known to be reasonably accurate).

I have enjoyed using this charger for a few weeks now, it is a solid unit and SMALL, which makes it very handy for charging a battery while it is in the car making those hard to remove batteries easier to work with. I did notice that over time it builds up an odd behavior where it will only charge with .5 AH during a charge no matter what the actual Current Setting is at (in my case 8 AH); this was resolved with a factory reset so the manufacturer provided a solution in case of the unforeseen. I do recommend this but I can not give it 5 stars as this is an issue that should have been picked up in QC; but since there is a stable resolution I do still recommend this charger.

We use it to charge batteries for small drone. We have five batteries, each battery lasts may be 15-25 minutes depending how we play. So we use the charger to make the toy available to play through out the day, without waiting for batteries to charge.We also appreciate that this thing can be powered from RC car battery (not just from AC/outlet), and it call also charge a phone (because it has USB output)I also highly recommend to get these extention/connector cableshttps://www.amazon.com/gp/product/B078TBLY7J/ref=ppx_yo_dt_b_asin_title_o08_s02?ie=UTF8&psc=1( 6pcs Connector Cable Molex Male to JST JST-PH 2.0 and Micro JST 1.25 Female )Together with the charge, this way when you constantly connecting/disconnecting the batteries , you are not wearing off the ports in the charger itself

Great for 1S whoop batteries. Love that it will do 6 batteries at a time, that it will accept all common connectors, that the charge rate is user settable, and that it will charge both LiPo and LiHv batteries. Easy to use and easy tounderstand. I won’t deduct from the score the fact that the “bell/ringer” is extremely loud as another reviewer noted

The product independently charges 6 batteries. The display cycles through each port as its charging so you can see the current voltage. You can select how much current you are charging with from .1A to 1A with .1A incruments.

The item works awesome at the moment. However I did receive one with a dead pixel line no big deal, but shows in quality control. i do wish that i could check voltage with out having to plug in a supply voltage, and that you could charge without the source voltage(3-40v?) plugged in as well as the balance leads- All my battery's are not XT60.... Ill make it work.

I bought this charger originally to charge a set of 2s batteries. Since then I have used it for a few other lipo batteries with different connectors that this charger happened to have. It does exactly as it said. Chargesd the batteriews quickly and has a nice readout to tell you the progress of the batteries as you go. Couldnt be happier with the purchase.. It is worth the few extra dollars over the others out there similar. Quality product and dependable. .
