Lithium battery

[rick danger]

Well, found this thread in a search. I put a lithium in both my KTM's and have had good luck with them. I'm just considering this because my ATV needs a battery, and the rocket's stock one can go in. So I'm considering this one. Antigravity XPS V-12 Lithium Battery - Left Side Negative Terminal This place is the best price I've found. Lots more in other places

Considering next time to replace the Battery to Lithium. Any thoughts?

Swapped to a LiPo battery and after initial good performance I noticed it performing like there was a parasitic leak. After much testing I was unable to located any drain. After leaving on tender and measuring voltages I noticed it would allow 2 or three starts in quick succession but no more. Also I was informed to leave the bike on for 30 secs before attempting a start. Nothing seemed to work. Checking the model battery online I noticed the R3R recommended version hand be upgraded 3 times in quick succession each increasing CCA. Discussion with the local bike shop I was advised that they had very little success with large capacity bikes and Lithium batteries. I then purchased a lead acid and all the issues disappeared. It will now sit for up to week not on a tender and start multiple timed in quick succession. The lipo is now serving in smaller stuff at home and working
fine. Maybe if a list is made of known batteries that work well as the LiPo s are expensive to blindly try.

7yrs on my Anti-Gravity, stock regulator. Never a problem, ive had it turn off one winter being in storage, but two weeks later it turned back on and charged as usual, It cuts off at a set voltage to save from discharge. High compression no problem, 900cca on my anti gravity hd. 7yrs and going strong, worth every penny to me, just knowing its gonna start! I can leave my key on and run the stereo 20 minutes and not worry about it starting. I do have led jw speaker headlight and led bulbs in rear light.

You must have more room on the first gen. Rocket. I just measured mine and the ATX 12 is as big as I can go. The 20 is 6.9 inches wide. The other dimensions are there same though. Shame. looks like they put a fuse block or something there on the new ones. The 20 is only a couple of bucks more too.

I bought a NOCO 20 12V they are so light. i dont know about how rigid they are but they are easy to charge them.

The 2.5s have decompressors that open some of the exhaust valves on startup. This reduces the initial compression, so the bike will start more easily. Lithiums are lighter, but one of the beauties of the power of the Rockets is that a small reduction in weight is not going to cause any significant difference in performance. I don’t have a dog in this fight, but I just replaced my battery and thought about paying more for a lithium for less than a red hot second before going with a conventional one.

Yeah, that's the thing about weight reduction. Its a cumulative thing. It all adds up. I couldn't believe the weight of the back rest on my GT. And up high weight and down low weight makes a big difference. That's why I'm not jumping on a full catless exhaust system. Its a good bit of weight ,but down that low isn't as important. But I'm sure I'll end up with one anyway. Now a nice set of BST carbon wheels on the other hand.....
