HOOVO 11.1V 120C 7200mAh 3S Lipo Battery Hard Case with EC5 Connector Compatible for RC Car Truck Buggy RC Boat Tracxas LOSI Associated Racing Hobby RC Airplane UAV Drone (2 Packs)

Arrived well packaged and balanced well. I have about 7 cycles through both of these batteries (I'm using them in an 8s application). They charge well and have held up great so far. EC5 connector quality seem good and hasn't caused any issues. With the 120C rating these, seem to be providing plenty of punch for a larger 8s RC vehicle.

People love to hate on every lipo and go nuts with charts/spreadsheets and talk about it ad Infinium. I have a bunch of Hoovo batteries and they are all stout. Had these in a V3 Granite and started getting LVC issues in a V4 but it's the new ESC that's the problem, only the 'best' batteries and Spektrum can cheat just enough to make it work, kind of a disaster. Dumped that junk for a BL120 WP G2 and zero issues since(stock motor is actually quite good without that 2-in-1 trash). Temps went down, got full Mah, went from zero to hero getting rid of that setup. Be weary of the new 223S series ESC. Of course in all my TRX stuff stock ESC or otherwise zero issues. A couple I've had for over a decade I can feel any difference in batteries or mechanical issues in seconds. Need to get a new drop tray to fit these in the TRX4 so I can go for miles... They are big and heavy though and the Arrma stuff is already heavy and hard on batteries. I'd probably recommend the 6200 as the best balance of weight/capacity for those. For much lighter TRX stuff, these run for a long, long time in a typical 3S VXL rig. 7200 is good for 'I just have one battery in a Stampede in the trunk and I found this place on the way to grandma's lets go!'. In a 2BLS I don't think I'd have enough personal time to try to run a 7200 out... Go 5200 on those(5200 is usually more than fine for most 3S VXL's too). It's a bruiser weight battery, but it has it's moments. Probably good too in a 3S boat. 7200 is good for one car/one battery/and a 'maybe' trip. Or if your kid had a few friends over and you send them out with a 2S rustler to play. I have 20+ Hoovo's, 2S/3S/4S, shorties, etc-all are stout none have died. Are they for racing? No, but best value to get a decent brick in an RTR for sure. Hater's are gonna hate...

This 7200mAh battery perfectly fits the 1/10 Arrma Granite BLX 3S, and features the stock EC5 connector. It lasts over 30 minutes of hard driving, and I have even had it last 45 minutes of continuous mixed terrain driving. I was only getting 15-20 minutes run time from a 5200mAh cell, so this provided a noticeable improvement. Although this is not a cheap battery, it is a fair price point, it seems well made, and it's worth the premium over the 5200mAh options. I appreciate the hard case packaging, as I noticed the other soft case batteries I have were getting dented during crashes. I highly recommend this for other 3s BLX Arrma's, or similar RC trucks that it will fit in.

Great

Heavy duty keeps charge longevity is great!

Barely fits in xmaxx. But works

I have a "first gen" pair of hoovo's that I really liked. They worked really well in my 1/8 Kraton EXB. So I bought these 7200mah 120C 3s packs thinking they'd be similar. I was extremely disappointed. IR (internal resistance) measured 30mOhms for both packs on my Hota D6+. IR on the two packs were still the same when then measured on my Imax B6AC. That IR is seriously unacceptable for a brand new lipo. For reference, thats higher than an old pair of SMC lipos i had that I retired at 28mOhms because it was getting hot enough during use to concern me that it would catch fire. The second picture I attached is the IR on one of my old hoovo packs (old style label) that's been driven hard for 6 months. It's still good, I'd say. These new packs are a far cry from the old packs. They used to have 10awg branded wire. And you could see it in the pictures. Now they don't even have that--go check the new style stock photos, they conveniently hide the wire branding. Not even going to bother putting these new packs in my Kraton EXB and run them. They are going straight to a return. If you want to buy a Hoovo, perhaps look for the old style. But I can't recommend the new style based on my experience.

Batteries were great at first. I have always ran 2s 6000mah Hoovo batteries in my 1/10 scale RCs with no problems. After a couple months of use, these 4s 7200mah batteries have high internal resistance, causing a loss of a motor and ESC. They have always been charged and stored properly.
