Amazing quality for the price. I used to be a Thunder Power Li-Po fan but it got hard to justify $70 for a battery. I tried this only because it was cheap but it's genuinely GOOD! The cells were already almost perfectly balanced from the factory with a good voltage as well. Works wonderfully with my brushless setup on a P-51 RC plane.

Not 50C battery, more of a 30C, exact copy of E-flight EFLB22003S30. Internal resistance is low and performance good for 30C.

I've flown with various high C rating batteries in my VisionAire and they all start to swell after a couple flights and of course, lose performance. The Ovonic 50C battery has had over a dozen flights and it looks exactly like it came out of the box. Fantastic + would be my rating. I just ordered more of them.

This 3 cell battery is marked as 2200mAh capacity. The unit that was purchased 5/2020 tested to 1860mAh after 10 cycles. Voltage range 3v3 - 4v18.Cells are well matched. Tested values 13 mR +/- 0.1 mR on each cell in discharge and 9 mR in charge with same tolerance.This battery happens to be exactly the same size as a Lumineer 1800mAh 3s battery pack.All tests performed with iCharger 4010duo.

Came perfectly balanced at storage voltage, charges to capacity, and runs as long as it should for the MAH in my scalers. Will be buying more.

I can get 25 minutes of flight time on my old Great Planes E-Cub that I converted to a brushless/ESC setup. Battery checks out to what the advertised specs are. Don't have a way to test max current output, but it's way more than adequate for what I use it for. Will be ordering a few more!

Got it today, charged it up, put it in and WHOA BABY did my AMP ECX haul some serious tail! Used it twice already and man oh man does it seriously boost the speed or what! Wow! Literally just got it today so can't speak on long term.just first thoughts. I usually run with a 5200mah 2s Lipo for longevity purposes and I have top speeds of around 25-30mph but once this 3s went in my Garmin clocked 41mph! Wowzer. Couldn't even go full throttle cuz it would want to wheelie in the middle of going…

I like that the battery is small and lightweight. I do not like that it losses the fully charged punch that is has when fully charged quickly. Not really suitable for a long rock crawling adventure but that is known by the low MAH count. Overall good short term battery for brushed motors

These batteries are far from great. They’re supposed to be rated for 50C, yet the plane I put them in travels MUCH slower with them. If I put a 2200 mah 30C battery in it, it’s fast as all get out. They can hardly power the smaller planes I fly, but they do work, just not well. Save yourself the let down and buy a better brand.

Gone are the days I need a 7 cell NIMH pack that takes up my entire battery compartment. This thing is the size of a small harmonica and it has my Stampede VXl doing 60 MPH! A heavy bashing session lasted 22 minutes with this battery, and It only takes about 20 minutes to completely charge up. Great battery and price.

Can't comment on longevity as just got 2 of these-4 flights and great power-3 cells all read even voltage-the cost was fantastic for this quality.

Used for RC helis, they are packaged well, all cells are matching in voltage, so far they are holding up well, time will tell, I have had lots of different lipo's over the years and these are as good as I have seen, first year using them we will see how long they last. I have batteries that have lasted 10 years same kind of lipo's, so I have high expectations for these also
