I generally take mine off , take it on holiday, treat to lunch,and then give it a good kicking if it won't start the bike!
Noticed that conquest carbon list lithium ion batteries for dukes surely if they can handle a bigger v twin the 900 should be fine. At the weight lose and smaller size appears ideal
I use one on my 999. LiPo 6 odd pounds lighter and charge in no time. mine cranks better than my old lead acid heres the cranking power of mine
These look very good batteries, one of those coupled with that "chunky battery lead" upgrade mod should be more than well worthwhile.
