Granted I have only used it once but it seems to be a very user-friendly model. As long as it holds up well it should be great. I do like that it will charge up to 10 Amps. I mostly run 3S batteries on a parallel charge board. This makes it so I can charge four of my 2200mah batteries in about an hour which is great.My previous charger which I still use is a Thunder AC-6. It is a good charger as well but maxes out at 5 Amps. This Keenstone charger is the same price with double to output so it is a great deal.

So far so good. Have been using for almost 2 months now. It charges my NiMH batteries just fine. I also balanced a friends lipo’s with it. It is nice when doing a forming charge is keeps history of the charge discharge amounts. Not necessary but it is handy. It does everything it is supposed to. I have charged 3S lipo’s with and I have have series charged 2 6 cell NiMH batteries with 0 issues.

As of now, this has done the intended job. We will see how it works in the long term. I have had several of these from other vendors that have not even lasted a year
Michael Rabens –
Mine arrived and is mostly as described.Instructions are not very clear for first time charger users, but after posting my issue (I didnt know to connect both balanced and direct leads in LIPO balance mode), it works very well!

For the price of this guy, I am very impressed with the quality. Does a nice job charging my lipos quickly and reliably, I have charged almost every lipo that I have with this guy and have been very impressed. Takes about 45 min to charge most of my 3s and 4s 1300mah lipos. I still haven’t tried getting a larger balance board for multiple lipos but I would imagine that this guy is more than capable of charging a few lipos in series. All in all I like it a lot for what it is. Also the “lil” octopus of charging connectors came in handy much more than I ever would have imagined haha

Seems to work great. The discharge feature did a perfect job moving a fully charged battery to storage voltage.

the directions were a bit hard to figure out but my grandson went on youtube and there was a video that explained it quick and easy. it works well
J. Waller –
I like this charger. So far so good. I have charged various types of batteries both small 2s and very large (264000mAh) 4s batteries and this thing seems to do a good job. I am charging the large batteries in 50A increments. I have not tried the discharge feature yet… I kind of don’t want to. I will update this review if I ever get around to discharging anything and there are any issues.

Took awhile to get it up and running, but it gets the job done. Lots of great features and comes with most chords for charging. An xt30 adapter would be nice, since those are getting popular, but thats just me being nitpicky. Performance for the price is excellent.

It looked like it might be difficult to operate but after the how to use charger on the keenstone siteIt was a snap , very nice charger so far , comes w/ everything you need to get started

Great charger. Charges fast and balances well (according to the charger). Haven’t had any problems at all. Stays cool and batteries don’t heat up either. Using it on 1 7c Nimh and 3 different 2s Lipo batteries.
Dan –
This is a versatile tool useful for charging very different batteries. I replaced all my old NiCd in my hand tools with Li-Ion, connected wires for balancing, and it works great. The instructions are not as detailed as I expected but you may figure out how it works.
Matt –
I really like this charger. The menus are the same as most chargers of this type, very easy to navigate. The looks and construction are very good. You get a large assortment of hook-ups to plug into your chargeables, and an S8 Tester that comes in handy, and is very accurate. The angle of the display makes it easy to read, with good background lighting. The only slightly negative thing I noticed is that if you charge at 1C or higher you do not get a good saturation (using 5S Li-On). If you go at 1/2C or less it will charge down to about 20-40mA input. There might be settings that I do not know of to make this better. I am never in a hurry to charge, so I just go at 1/2C and get good results (note:I am Bulk Charging, not Balance Charging).

Best 10 Amp for the money with decent reviews. Some times it glitches slightly at the end of the battery charge but since i never leave charging batteries and know about how much time it takes i am able to reset and finish charge. doesn’t happen very often and i don’t know what causes it. I do direct charge and have used a board for up to 5 batteries. Shuts down automatically after balance; charge, storage mode and discharge. I have used all three. Simple to use and figure out. Start to select and – and+ to move up and down selection. Hold Start to begin. easy. No off button so you have to unplug.

Works great exactly what I was looking for. And very compact.

I’ve charged, 3s, 4s, & 6s batteries and so far the charger has performed great, the cooling fan helps keep the unit cool during long charges. I’ve done more than 20 charges with and it’s performed great.

High quality charger. Does way more than I’ll ever need it to. I like it.
C. CANFIELD –
Very happy! It is so easy to use and program, and I love that with the charging pigtail can work with many different connectors. I like having more control of what the charger is doing versus the Traxxas chargers that work but just seem to be too automated. This also allows for discharging which is the reason I bought it and I use it every time I need to.
Kurtis Whynaucht –
Has worked well so far. I’ve had to buy some other charging connectors and whatnot, but otherwise charger is all that they said.
Billy –
So far, charges and balances my lipo packs as advertised. Haven’t had any issues. Good value for cost for me.
Marino –
This is a great little charger for the money. If you want something fancy that has a higher discharge rate, or that can do multiple batteries at the same time, or that has an on off switch (this one turns on and off with the electrical plug), then look elsewhere. If your looking for a simple charger that’s easy to use and does it all, look no further. Works really well and is user friendly. You can’t go wrong with this great little unit.
Chris –
Love the fact that you can crank the amperage up. Charged 5 610mah 2s 7.4v batteries on a parallel board without a problem. I am new to this, so make sure to get some info on youtube because it was a bit of a learning curve. However, it seems to use the same interface as other chargers out there, so maybe it’s not so different. In either way it does the job.
Cristinel P. –
I looked for a 24V Ni-Cd (among other kinds of batteries/cells), but did not find something worth the money… untill I have found this charger… It’s PERFECT! Small, yet powerful, double input power (120v/220v AC and 11-18v DC), full set of output charging cables, including DC input cable, even including a voltmeter! Could not have been better than that! Instructions are not so detailed, but easy to understand and apply. And last, but not least, the price is unbeatable!!! I am VERY satisfied!
Twon423 –
This thing is super rad! I can charge nearly ANY sized lipo in about 45 minutes!!!!!!I’ve been using the regular 2s/3s wall charger and it takes it like 6 hours to charge a 5000mah battery up.That alone should hook you right in! I was used to charging 4-6 batteries the day before I planned on running my rc trucks and now I can charge them right before I leave. And I can run the rc’s multiple times throughout the day if I wanted to!!Real game changer folks.If I had one complaint, it’s that you can only charge one battery at a time. But I can’t complain because it’s only $45. I’d have to double that price to get a super quality dual chargerWith all of the attachments, you can charge nearly any battery you may have on hand. From lipos to sla scooter batteries, you’ve got the power!
John M –
Versatile charger with many great features. Great value. Not for the beginner as it takes some dialing in and you can do dangerous things with LiPos should you not have the correct settings. Know your stuff and do your homework before using.
Sean McMullin –
It’s intuitive, simple to understand. The instructions could be a tad more clear, but I am a technophobe…lol. LOTS of connectors for many different battery types. Charged a 5000 mAh battery in under an HOUR. So far, quite impressed.

This is the only 100W (10A) charger in this price range that I could find that would charge HV Lipo and that plugs into the wall. It works really nicely, charges fast as advertised. I’ve only used it for 2S 5000mAh LiPo’s so far, but for those it works great, and it does deliver 100W as advertised. It’s physically very small which is great, and it has a fan to keep itself cool on the inside. The fan makes some noise but it’s not offensive. My previous charger (Thunder AC6) does not have a fan and it got really hot, especially when balance charging. This charger stays significantly cooler with the fan. Anyway, it does what it says and is easy to use, I would buy it again.

The charger itself is just great. It has many different programs for many different types of batteries, and adjustable programs for charging, discharging and cycling. That being said I have to tell you that the instructions leave a bit to be desired as they are written in what I call “Chinese English”. The author knows his product but isn’t 100% fluent in English. Overall I recommend the charger since it is a very good product at a reasonable price.

Works well and wasn’t overly difficult to figure out. It charges my LiPo 2s 5200’s in about 45 minutes and does not make very much noise yet.

Good charger. It operates the same way as quite a few hobby chargers that have this same interface. 4 buttons and a blue backlit screen. If you get confused, just hit up YouTube and there are several tutorials on how to operate this charger. I use 2 different parallel boards with this charger and they work great with it. Charger has the capability to do HI-VOLT Lipos as well.

This battery charger/discharged works as described. It took some time to get used to how the menu system works, so don’t get discouraged if you need to time on the “learning curve” to get everything that it does. Once you’ve been on it for a while, it will start to click for you. The instructions are not clear, and I had to go to the internet to get some clarity on which cables to use for which batteries (it will work on many!), so if at first you don’t get it, go find some help on the internet! Once you understand how it works, I’m sure you will see that this is a great charger.
Dr. John F. –
Perfect and safe for charging various types of RC batteries

Works well. Bought it as a second charger and was suprised how fast it balance charges my lipos compared to my older charger.

Works perfectly. Loud tones letting you know its charged. Very convient. Love it.
Nate –
I have been looking for a lipo charger for my traxxas when i came across this. for the same price as the traxxas ez peak plus. It can charge up to 6 cell lipos, the traxxas up to 3s comes with lots of connecters and space to solder more on. it dose ten amps the traxxas dose 4. can decharge batteries the traxxas cannot and this is all for the same price!
Casey –
Well first time purchasing a lipo battery charger. I didn’t know you needed one for upgraded drones. I shopped compared etc., found a decent deal which is still holding up. To my surprise it chargers 6s batteries a lot quicker than I had originally thought. But either my first remote control was a dud and my second has missed its original delivery date, so I have only had the opportunity to use it 1 time on three batteries. Directions were accurate and I performance issues. So right now I’m satisfied whenever the remote arrives I’ll add to this is performance declines, otherwise I’ll keep it as being satisfied and recommend to others looking for such a charger
BMoore –
Battery charger is simple to use and is good size for packing on trip or put out of the way. Works good on lipos. Order received on time and as advertised, all the accessories described are included.
S. Short –
This Keenstone battery charger is a sleeper. You wouldn’t expect to have such useful and amazing features along with good quality.But underneath the pinnings of the case contains a Peak electronics circuit board with all mid to top tier SMT. No weird, unlabeled crap inside. I went and salvaged mine after not paying attention and hooking up a pair of 800cca batteries backwards to the charger and turning it on .. palm to face….I watched the reverse polarity send a spike of electricity travel through the entire unit, seemingly slow motion like “awww nooooo”.. it legit looked like the remake of the Tron movie, the way it zig zags through the PCB and stopped at the voltage regulator SMD that melted.Could’ve probably been repaired, but didn’t have the tools or know how then, but just wanted to share that after having my fair share of ,”oops” this BMS battery charger is a good one. I later got a new tenergy one but miss this one despite tenergy being grate too, the Keenstone had more readily usable inputs off the board. Good job whomever selling this for real.Only negative is it’s not fused and obviously wasn’t or isn’t reverse polarity protected in any way.

Excellent, however buy the one that charges 2 batteries at same time. I made a mistake and bought this one, I wish I bought the one that changes 2 batteries simultaneously.

I like how versatile this charger is, in addition to supporting quite a few battery types/chemistry, it also comes ready with flying leads with most of the common connectors right out of the box and even includes provisions for adding your own connector. I also like that this unit has an integral power supply but can also operate off a battery as well.About the only thing I don’t like about this charger is the included breakout board for balancing, the wire isn’t nearly as long as I would like. Minor complaint.Overall I feel like the performance is fantastic and the price makes it a great value. I’m extremely happen with it and I’m considering buying a second.
Sitnski –
Have been using this charger for over a year and typically balance/charge 6 3S 2200mah batteries at the same time using a parallel charge board. Takes about 110min. total with batteries starting at 3.6-3.7v. never gets hot. I only charge 4 3S 2200mah batteries at a time when powering from my car battery at the field when my son and me are flying a lot. But I charge them at 2C to get them ready to use sooner. I have to watch it or I drain my car battery and have needed a jump start before. Highly recommend.
Richard T Smeltzer –
Great charger. Can charge any battery you have. You can even hook it up to a car battery for charging out in the field. It is a bit complicated to operate.
Ryan R. –

Absolutely love this little charger. It has a battery voltage measurement function for when you just want to check the individual cell voltage without charging it, and also an internal resistance measurement function. It comes with a free battery buzzer for checking in the field, and also has every kind of cattery connection you would need. Also the switching power supply is built in so you only have to run a thin AC power cable to it and not worry about a power brick. It does have a DC power input where you can power it from your car or a hobby power supply easily. Lastly, it has a “digital power” function that can allow it to act as a small power supply with adjustable voltage for other gadgets that need DC power.My only complaint is that the included multi-ended cable for all the different connector types can be a little bit dangerous as it includes alligator clips as a connector and they can easily short out on each other causing your connected battery to short, possibly resulting in a fire. I would recommend buying a charging cable appropriate for your needs, I bought an XT60 charging cable and have no issues.
