Some FAQ's of interest on shoraipower.com ~~>
Of particular interest to me is a chart showing voltage of the battery at different percentages of capacity of charge. Our regular battery is 12.7 volts, if it's "full" charge; 100%. The Shorai doesn't drop down that low, until 10% capacity of charge. And ranges between 13.3-14.34, 90%-100% of charge. I know when my current "standard type" battery is at 12.7 V, versus maybe being at 12.5 V, the machine starts easier, and the starter is "alive" (with a bit more authority) when it slams the starter clutch. Also, one would have to have better spark at "12.7V" versus any lower voltage reading, that would show on the multimeter. In cold, cold weather 12.5V won't provide near the cranking power or spark, that 12.7V or above will do. I use my Greenlee multimeter a lot. "14.34V' or anything above 14V, or even 13.5V, stands to reason, starter is going to kick the starter clutch harder and faster and with more spinning torque=(?)better engagement. T99Ford in one of his posts in the thread telling of his mishap, tells that Shorai told him they had redesigned the battery for "safety" purposes, and the process had reduced cranking performance by a minimal degree. So now those voltage numbers in the aforementioned chart may not apply.
Also, cywelchjr mentions above re "...... stable charging on that battery would not be met by the XS charging system..........." May-be. Bob Jones, RIP, mentions in his book XS ELEVEN HEAVEN, that the charging system of the XS11 is a superior charging system. He had also mentioned same, several times when he had his fabulous website. I have book #161; gosh, I wish he'd gotten book II finished.

) Shorai is a really standup company, with a terrific product. 
. They have a lot of the good characteristics of the battery in your laptop (stable voltage down to a very low charge state, no memory, no sulfating) plus they are not as volatile, not toxic like the laptop batteries AND handle both fairly high (for battery size) charging rates and pretty high discharge rates, right down the minimum usable charge level. My average on cheap walmart batteries has always been about 2 years, at that rate, they cost only a little bit more, rather like moving up to a premium standard battery, with a LOT more reserve capacity.
