Here is my impression of Shorai as used on my Ducati Diavel 2012. True does not like the cold. However, it cold starts early in the morning with temperatures about 0 -10. I turn the bike on and leave it for a few minutes - starts every time. Needs some cranking, then fires right up. Never been stuck. Bought my Shorai from Glen(Flying Squirrel). Battery crashed on me completely. Shorai wanted me, at my cost, to send the battery to them in the States, via UPS, who at the time wanted so much paperwork re lithium, they where a complete joke. Lucky for me Glen is the man. Took the battery back and said he would deal with them at his expense, returning the battery. The next Shorai sat for about 2-3 weeks and went flat. A quick charge from a regular charger (non sulphate) and came back to life in about 20 minutes. Took it down to Glen to check the battery and the Shorai charger and said all was good. Now have the battery in the house and without a charge it is holding at 13.28 for the last 3 months. Stick it on the bike soon, as I am away in sunny cold Florida.If anybody is interested in the follow up please let me know.
