  1. Bill

    I run a bike shop and switched to Lithium Batteries a couple years ago. Even though I had some issues with other brands they were good about it and I never looked back. When I started using The Antigravity Batteries the issues that I had with other brands stopped. Now I can start a big inch motor with zero issues. Customers are happy, I am happy. What else could I ask for?

  2. Clint Gabrielle

    I went through three different batteries before trying antigravity’s ytz12-20, having a big inch motor the other batteries wouldn’t spin it for long the ytz12-20 spins it like its a scooter deffinetly the best battery I have used. Antigravity’s support in my opinion has to be the best in the industry, Eric was very knowledgeable and easy to talk to and they shipped my battery very fast.

    I have a 113″ 2004 FXDL with 10.5 pistons. This battery 600amp starts it time after time. Even with compression releases the stock battery had problems. I’ll be a return customer. Thank you for a better then good product.

  4. NSWU.

    Big compression Street/strip motor with 24 volt system, put in a ytx12-20cell to see if it would start the bike. It doesn’t spin quite as fast as two batteries but it starts it like it has a stock motor in it. Good by to all the 2 Batt, headaches.This is one hell of a good,powerful Battery. ILL NEVER USE ANYTHING ELSE !!!

    Wow, I shed 10lbs off my custom bobber and added more cranking power for the 120″ engine. Well worth the extra $!
