HOOVO 3S 11.1V Lipo Battery 2200mAh 50C with EC3 Plug for RC Car Boat Truck Multi-Motor Heli Airplane Quadcopter Helicopter Hobby

Work great, perfect size for my eflite planes. Last a long time and a good deal.

These batteries fit and work great for the grom Rc cars.. Perfect size and punch to get them ripping..

Just about the maximum dimensions for the typhon grom. Hasn't overheated yet and to note it is not a hardcase. Paired this with a hobbywing 16BL30 ESC and Quicrun 2435 4500kv motor (used Losi 18t pinion 2.0mm). I need to get some stabilization so I don't know top speed but it will easily push it over 40mph. Run time is better than 25min per battery. Good amount of power and the quality is there. No problems charging them with my spektrum s2100 charger. Definitely recommend

They work fine!

2 of these are basically the same price as 1 Spektrim 2200mah smart battery. They last around 7 to 8 minutes in Blade 350 QX2 and have also used them in my BF109. I have maybe 10 charge cycles on each of them and no problems so far. They seem to balance well but I think they fudge the C rating a bit. Overall, good price food q uality

i bought bunch of these not one issue

I have had two batteries already reach the end of their lives after five months of light use. One I have used in a float plane and it gets stranded on a regular basis because the battery does not hold a full charge anymore. Update: they claim a "warranty" but no contact information is available. This is a company best avoided unless taking risks is something that you enjoy. I would stick with reputable US or (insert country other than China here) manufacturers.

Exactly what I ordered and solid performance.
