That's pretty good battery for its price: - 2400-2500mAh (tested on genue iMax B6 and it's ACM copy; I have 3 of these batteries) - high continuous discharge current ~50A - relatively good burst current ~70-75A - good results at high stress applications (2.36 minutes at ~50A till being fully drained; ~2Ah capacity) - good results at cold weather (~30A continues discharge at 0 C) - good buid quality
- that's not a 2800mAh battery like advertised - it's not 30C, much closer to 20C - not ready for operation out of the box (soldering connector is required)
I use these for RC car, studio lights and flashes and mostly for airsoft replicas. Airsoft replicas require continuous discharge ~20A, so I think those three batteries I've got would last for at least 3-4 years before I would need to replace them.
Highly recomended for airsoft, medium-power RC models, high-power photo light and flashes.
