Yes and no. It's all about how much current (Amps) can be supplied by the battery. Car batteries are Lead Acid, and this technology cannot supply anywhere near the amount of current (pound for pound) of modern lithium based batts. That said, it will work, albeit with reduced performance and/or more weight/bulk.OK!
Will this stuff work with any sort of battery, e,g, car batteries.
If you are just testing things, then SLA's would will be enough to prove its all working.
In the real world, SLA's don't make sense on a bike anymore.
