The 18ah Shorai has approximately 6 ah of power available at full charge. This would be at 14.4 volts. If your resting voltage is less than 14.4 then the capacity is reduced from 6 ah.
The same is true for other brands of Li batteries. Multiply the battery PbEq advertised AH by 1/3 to get actual AH at 14.4 volts.
The PbEq is a measure of the battery's ability to flow current on a very short term test.
Small Li batteries will briefly flow current like a big lead acid battery. That means they tend to work well for starting, provided the bike is a reasonably quick starter.
I see Podtronics is now selling a regulator for Li batteries. It works at a higher voltage range than the regular Podtronics, which is set for lead acid battery charging.
