Works perfect on 2nd bike with shorai battery. Made tending the battery a snap.
Kit includes two parts: one wire harness which plugs into battery and second harness which plugs into charger. However, if you have purchased charger, you would already have harness which plugs into charger. I have multiple bikes with Shorai batteries and really only need the harness which connects to the battery (which I keep attached to the bike and battery). Better if Shorai sold harnesses individually and allowed the consumer to save a few bucks. Plus, I end up with a bunch of harnesses which I don't need which means more trash.
There have been no questions asked about the Shorai 12V Extension Cable.
