Looks like my new Banner is toast (not holding enough charge to start the M3W, even after a run and staying on a CTEK conditioner). Of course it could be the CTEK *and* the rectifier are the problem (unlikely). Car voltmeter shows 14.2-14.4v on a run, and 12.4v at rest. I could buy a new battery charger, then a new battery... but noticed the motorbike world seems to like the Shido batteries. <£200 for a Banner replacement in size, 2Kg, and 480CA amps ... only also needs a Lithium charger.

See the LIX30 in their catalog.
They also do one that connects to an app... wow!
