In case you don't know, I'm a dealer for Antigravity Batteries. I got my first order in the other day and wanted to do a weight comparison. First things first, these are lipo batteries. They are made in the USA. They are not the cheapest battery out there but they are definitely one of the better ones. The terminals on these batteries are rock solid. The guy who started making them is a racer and was making them for racers one at a time. Eventually he started the business and is now working on getting more advertising. These guys retail at $169 I believe.
The antigravity battery 8 cell version weighs in at 1 lbs 12.8oz
The AGM FZR replacement battery weighs in at 7lbs 15.6oz
The AGM R6 replacement battery weighs in at 5lbs 14.8oz
The FZR and R6 batteries run between $40-50 shipped. So, it's a definitely price increase to run the lighter weight batteries but if you're doing a custom install or really need to save every pound you can, these guys are the way to go.
