Howdy, folks. Some time in 2012, BMWON had a review of a device that, if I recall correctly, enabled you to charge multiple motorcycle batteries using a single charger (like a Battery Tender. It was not itself a charger; you use it with a charger.

I cannot recall the name of the device, and all my ONs are at work for redistribution.

Anyone know what I am talking about?

thanks, bws
