First of all, hello all, first post here.

I am planning a motorcycle conversion and ran across these. http://www.shoraipower.com/

Currently they are out of stock waiting for a shipment but they have been selling like hotcakes in the motorcycle world. The prices are really good, I believe the 18ah was $189, if I remember correctly. They are not listing the prices now.
They have no BMS, the new shipment is getting updated with an overcharge protection circuit, apparently there has been a problem with some stock bikes and their regulator/rectifier compatibility.
I am thinking the form factor on these is perfect for a bike conversion but I am not an expert on lithium or electric conversions. I do have 2 decades of experience with lead acid power systems and know that I prefer to stay far away from them.
Has anybody looked into these or any thoughts?

Not sure they'd give you the capacity you need. Do you have specs?

This is all they have...the largest one.

Voltage (V):
12

A/Hr PbEq:
18

Cranking CCA (A):
270

Weight (grams):
960.00

Weight (lbs.):
2.12

Max Charge (A):
18

Without continuous current ratings and discharge curves, I'd avoid them. 270A is impressive, but Cranking amps are not usually for more than a few seconds to crank the engine.
