Wow......That's expensive.Antigravity batteries are superb and have that failsafe re-start button, I'd have one in a heartbeat. But for us down under the cost is astronomical like $1200 or so, so it's a no go from me.
How does that compare to a good quality AGM battery in your part of the world?
I have located a potential source for a good quality stock battery here in the UK:
£420 for Lithium compared to £125 for a replacement standard battery.
I can't justify the extra cost.......In the case of the Triumph Rocket 3, I can't see that the extra cost justifies the potential benefits of lithium.
I can see that if I was building a Special and I needed the compactness and the lightness etc.... but I can't see it for a regular Rocket 3 rider, like myself.
