Zeee Premium Series 3S Lipo Battery 4200mAh 11.4V High Voltage Shorty Battery 120C with XT60 Plug Soft Case HV Lipo Compatible with Rock Crawler Helicopter Airplane Drone Boat Racing Models(2 Pack)

I put these in my Omni Terminator and I could tell an immediate difference over the battery it came with. The are high voltage LiPos so make sure your charger can handle that for the extra punch. You can charge them as a normal LiPo and they will still give you plenty of power at 120C. They last a long time in my truck and were well worth the money.

Delivered a day early and packaging was excellent. The product works great on my first time out. Can't go wrong with the item and the seller. ..

Plenty of punch and cells were matched exactly at storage voltage when I received them. Wires were good quality and the batteries have equal run time and they stay balanced. (I bought 2) Good price and fast shipping. Haven't had them long so cant say on longevity but everything so far tells me they'll be good for a long time. I'll buy them again if I need more.

Fits perfect in RZ001 Monster truck without mods

last a long time

These aren't a name brand expensive battery but after going through several cycles with them with no problems, I really recommend them. They are the perfect dimension for airplane and give me 10-12 minutes of flight time when drained down to 3.5 Volts per cell. The product performs well for the price.

I purchased these batteries to wake up my Chinese ready to runs. These batteries pack a punch, have decent run time based upon the size, and fit( mostly, maybe a few modifications are needed) a wide variety of RTRs. They are soft case LIPOs so be mindful of how and where you install them.

I charged one of these up to full capacity at 4.2 volts per cell and then discharged it at less than 25 percent C. You can see the results in the picture. At a point where a little less than about 90 percent of the battery was discharged, the actual capacity was around 1600 mAhs which is less than 40 percent of the rated capacity. This was nowhere near the actual discharge rate one would be using to fly an aircraft. I expect that under those conditions, the capacity would be even less. I purchased these because of the size, weight, and supposed capacity to fit into an Eflite Apprentice STS 1.5 which takes 3200 mAh batteries. Because of this, now I am going to have to test the other Zee 3200 mAh batteries I purchased recently. The bottom line is that these are not worth it and will be returned. You get what you pay for.
