Hilldow 7.4V Lipo RC Battery 2S 120C 1600mAh Lipos Batteries Rechargeable with Dean-Style T Connector for RC Models Airplane Helicopter UAV Remote Control Quadcopter Drone FPV(2 Packs)

I’ve only used one so far in my small rock crawler, for about 45 minutes, and it’s not dead yet. So far, so good!

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..

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

One of these brand new batteries was DEFECTIVE! It was DEAD right out of the box. I requested a replacement now the seller wants me to jump through hoops (print a label, box it up and take to shipping) to return a defective product! I cannot even find a way on contact the seller to resolve this! Horrible! Highly do NOT recommend!
