PulseTech QuadLink Battery Charger

PulseTech’s QuadLink works with any 6- or 12-volt charger to charge up to four batteries at once. The unit works by automatically splitting and distributing charge output in 10-minute segments to batteries hooked to the QuadLink. It can be mounted to a wall or bench and comes with four eyelet lug adapter cables and four 5ft extension leads with standard SAE connectors, making it easy to use on bikes already wired for a charger. The unit we tested worked exactly as advertised. $99.95.
