I just bought a 9.6v 5000mAh NiMh. I figure using that will save me money in the long run by not blowing through so many BBs. I understand the 11.1v lipo is a beast and you'll be spraying BBs down range like crazy with it, so I just decided to go with the slower 9.6v to save $$$..
But if I DID ever want to go with a lipo, I saw the vid of the girl explaining it where she says it has to be an 11.1v 15C and no higher, but she never said what mAh to get. So should I be looking for the highest mAh possible in an 11.1v 15C?
PM sent to your question. Re-posting it here.
I'll address each question separately.
1. I've been using 11.1v Lipos for years and have never gone back. They are compact, efficient, and have become relatively cheap. Yes, they increase your rate of fire. But they also give you a better trigger response which IMO is more satisfying. BB's are cheap, I wouldn't worry about dumping too many and the best players only shoot what they need, they don't not spray and pray!
2. The 15c rating determines the continuous amps that a battery can deliver. The concern is two fold 1) too many amps causes more arcing in the trigger and the contacts wear out - this takes many thousands of rounds. Also, the higher the C rating the more expensive that battery. 2) Higher C ratings allows the voltage to remain higher longer at the beginning of the dump cycle of the battery which allows for a higher rate of fire longer. In many airsoft guns this voltage can cause "over-spin" which can be a PITA. For instance a double shot might occur in semi-auto. The fact is you are typically fine up to 21 amps continuous in a stock gun which is a battery with a 15C rating at 1400mAh. (15C x 1.4A = 21 Amps Continuous). Big C rating are better suited for R/C helicopters where that power is needed to avoid crashing your $3000 craft while doing acrobatics. At the end of the day, a 15C 1400 mAh is all you need for an airsoft gun. And these batteries only cost about $10.
Keep in mind that when you go lipo you need to take precautions (lipo bag) and have a good balancing charger. That said I believe the benefits are well worth the effort and investment.
Hope this helps,
