Rated 5 out of 5 by from Very Capable Battery Not exactly a bike application but I'm running two of these guys in series for 24VDC to power a robot platform. Great performance and very light weight. So far so good. Excellent service from FortNine as well.

Rated 5 out of 5 by from Small and super light!! I bought this to replace the stick lithium ion battery in my KTM. This one is even lighter and smaller than stock. We’ll see how it holds up to a season of riding.

Is there a difference when it says Lithium, and Lithium ION? Would this work with a 2004 Honda CB599 Hornet?

Do I need a special battery charger for this battery? If connected in my minibike, will the alternator keep it topped up? Also - will a 12 automatic battery maintainer work on this if I leave it connected?

Asked by: BrianK
A conventional charger wont be able to charge it i think because its lithium, i purchased the battery tender charger for it wich can switch from conventional to lithium and comes with wires that stay on the battery gor when you want to trickle charge it
