I've noticed something odd. I have an Elite Force 9.6v 1600 mAh (hereinafter "EF") butterfly battery, and an Enrichpower (hereinafter "EP") 9.6v 1600 mAh butterfly battery, but the EP seems to have much better trigger response. I just got a brand new Krytac Trident CRB and was testing out the trigger response. I noticed that with the EF, there's a very noticeable winding-up before the shot. With the EP, the shot is almost immediate (about 2x quicker). This was apparent even after topping off both batteries. My CRB also seems more prone to the trigger locking up in semi mode with the EF. I am unable to discern any difference between the two apart from branding; there's not much to go on. One came with my G&G CM16 Raider CQB, and the other one I bought concurrently at the store. Any thoughts? I'm worried I'm going to have to research batteries now before buying. P.S. I'm not interested in LiPoly as they seem like a hassle. I go months between airsoft sessions, and don't want to deal with something that will light my house on fire if I leave it alone.
