For those of u that own the small Antigravity battery be sure to hook the tender up to it. This is now my second one that I have killed. First one was a bad wire off the alternator causing me to lose power and run off the battery alone till it died. Well, it never came back to life after that. I was fine with that. It is what it is its a Lithium battery and they have there down sides. The second one killed was simply because im a jackass and didn't put the tender on it. Got down to like 10-20 degrees for about 10 days and I didn't have tender on it and it died. I may have some sort of parasitic loss coming from the stereo system or something I dont ****ing know but nonetheless if I had the dam lithium battery tender on it I wouldn't be out another $500 smh.
