And they cost a ton to buy. They have been raising the prices for a while now. They are becoming the next boomboombatteries IMO.
I bought from them back when their prices were good. Years ago they sold a 3s 4000mAH for $99. This was a very good price at the time. Today it is $149 (+50%). This when just about every other LiPo brand has gone down in price over time. It's just not worth it.
