Flat battery

Yes, every time a battery discharges it is a little closer to death.  An AMG more so than a wet, LiFePO4 even more.  Fact is a resting voltage at 12.866 or less can be fatal.   AFAIK, your battery needs to go back to Shorai for testing as there is no field test presently.  http://shoraipower.com/lfxcheck

The mechanic thinks the problem is the battery.  He has had the bike for a week and reckons the RR is charging the battery OK (I think based upon the fact that the voltage goes up when the engine is running).

If I can get the bike charged up enough to get it home, should I plan on replacing the Shorai or moving onto a different brand?

My preference is the AGM battery your bike came with unless your bike is a track bike or occasional canyon carver.

Any particular reason?  I was led to believe the Lithium battery would last longer and be less temperamental at starting the bike (assuming mine is a bad battery). It is certainly a lot lighter. I don't do track days. In fact, I mainly commute 15km to work and back.

The bike is being recharged. If I can get it home I was planning on doing a final test at home and fully charging the battery and then testing it daily, out of the bike, for a week. Shorai seem happy to have it back for testing and it is possible it will be replaced under warranty. Otherwise I would certainly consider other brands.

Reason being the high voltage needed to be maintained by the bike charging system and the likely possibility that charging system failures or even leaving the parking light on is likely to result in needing a new battery.  Last longer?  My last AGM was still starting the bike at seven years old.  Just figured it was time to replace it.

Fair enough. If I' month looking likely to get a free battery, under warranty, I'll look into this. Thanks

+1 on that, I went back to a regular battery and kick myself in the ass over the money I wasted

Advice taken.  I'm getting an AGM put in (or I will put it in, if the LiIon is capable of getting the bike home).  The question is weather I try my like with Shorai at getting a refund or just clock it up to experience!
