Update on my 1 year old Shorai. Now that the weather is just a bit warmer, it's been behaving OK. Until testerday.
Two weeks ago Friday (4/19 to be exact), I was headed out of the country with a scheduled return yesterday. So I figured lets give the "store" function on the Shorai battery charger a try. I do so and it looks OK, so I leave on my trip, not giving it another thought. I get back last night and both charger lights are flashing - indicating a severe over discharge. I put it on "charge" overnight. This morning both lights are still flashing. I put a voltmeter on the battery and it indicates 8 VOLTS. This is, indeed, serious over discharge and the charger has done nothing to rectify it.
I'll see what Shorai has to say, but here is the great irony: When I replaced the battery a year ago I put the original battery on a shelf in my carport where it sat for a year. It wasn't on a charger or anything and sat through the winter (though this ain't Wisconsin). I check the battery and it shows 12.4 volts. Hmm, not too bad, I think. So I pull the Shorai and reinstall the old disfavored lead battery in the bike. All the lights and instruments come to life and the bike fires right up.
