Hilldow 11.1V Lipo Battery 3S 65C 2200mAh Lipos Batteries Rechargeable with XT60 Plug for RC Models Airplane Helicopter UAV Remote Control Quadcopter Drone FPV(2 Packs)

Fits perfectly fast delivery

These fit perfectly in the battery tray of FMS 1/10 Atlas and Mashigan, I do not have the FJ yet, but I see no reason it wouldn't fit perfectly too.

Works great, lots of power, lasts longer that original battery

I ordered these LiPos to use in a 1:18 scale car that can only accommodate up to a 21mm thick battery. The photo in the description shows the dimensions to be 20x30x70mm but unfortunately the packs are actually 25x33x70 and don’t fit my car. Also, the photo shows the packs weigh 105g each where they actually weight 120g. After carefully studying the fine print of the description I see that the dimensions are actually described correctly but unfortunately I went by what the photos show when I ordered the packs. As none of the dimensions or weight in the description photos are accurate I wonder if the 120c ranting or the 1600mAh capacity are accurate either. Buyer beware! At least read the fine print if the size is critical to your application.

can't go wrong with these.. I have the cheapo to empty wallet lipos.. these are decent..

Admittedly, I just got these in today and have not yet charged for testing. They look tiny... supposed to be 1600mah, but they're smaller than my 1550mah AND my 1300mah 4s packs.I bought 8 of them and surprisingly none were DOA, and all cells were balanced with each pack reading either 3.82 or 3.81.I'll get these charged up tonight and report back tomorrow with how long they last.. could go either way but I'm not hopeful given the size.**Update**So they're definitely not 1600mah. Flight time on on my 5" freestyle quad is about 2m45s - 3m on my 1300mah packs and i was lucky to get close to 2m30s with these "1600mah" packs. Pretty disappointing, but I do have use for them with my smaller quads.. so I suppose I'll keep them.**Buyer beware!!

Did not expect such a compact battery. These are shorter than normal batteries, so you have to adjust for weight in your airplane. Be careful when ordering batteries like this.

These work well in my 4S glider
