I purchased these 6.5 years ago and they have worked flawlessly for the last 450 flight hours. I have a pair of these in my airplane and they are half the weight compared to a single lead acid airplane battery. I have no hesitation about using these. I have never accidentally left my master or on left it months and have it die, so when you hear people say how the battery does not stand up to being abused like that, know that no battery does, and these are more expeinseve to replace then cheap heavy batteries. Treat it well and it will treat you well.

Light and so far works.

My AGM battery was killed twice due to leaving the switch on. This has protection to not kill the battery from leaving things on. The weight is a huge difference as well for sport aircraft use. No cons.
