Never stranded again… Antigravity Batteries introduces the groundbreaking “RE-START (RS)” line of batteries – the first batteries with built-in jump starting! The revolutionary ATX20-RS RE-START Battery intelligently monitors its status, and just before going completely dead puts itself to sleep with just enough energy to get your vehicle started again. Simply press the RE-START button located on the battery, start your vehicle and drive away… No more dead battery emergencies or being stranded!

The new ATX20-RS is an extremely lightweight and high-power Lithium-Ion replacement battery for the heavy lead/acid YTX20 battery found in many Motorcycles and Powersport Vehicles. The ATX20-RS offers the first FULL Battery Management System (BMS) found on a Powersport Battery and includes low-voltage cut-off, over discharge, over-charge, and thermal protections with real time lithium-ion cell balancing. If you want to also track your battery status via Bluetooth, you can use the Lithium Battery Tracker.

Automotive Applications

The ATX-20 Re-Start battery can also be used in Hi-Performance Automotive and Racing applications where extremely high cranking power and massive weight reduction in a very compact size are desired. Due to lower amp-hour capacity, not recommended for Street-use automobiles.

As with most all our batteries, you can easily bolt on our Automotive Terminal Adapters(AG-TA-1).

To give you an idea of the power of this battery, the ATX20-RS can easily start Motors up to 700 Horsepower yet the ATX20-RS weighs LESS than 5 pounds! At a massive 680 Cranking Amps in an extremely compact size, this battery offers the most power in the smallest package you can find for your vehicle. Additionally it features our exclusive RE-START feature so you won’t get stranded with a dead battery.

CRANKING AMPS: 680 CA

AMP HOURS (PbEq): 20 Ah

WEIGHT: 3.8 lbs

LxWxH: 6.8 x 3.4 x 5.1″

 


Re-Start Battery Top View

First Motorsports Battery with built-in RE-START & BMS.

New 4 Terminal Design for easy installation in any vehicle.


  • Most Advanced Lithium Battery on the market.
  • World’s First Battery with Built-in Jump Starting, using our RE-START Technology.
  • World’s First Powersport Battery with a FULL Battery Management System (BMS) including Over-Discharge, Over-Charge*, Thermal Protections and Cell Balancing.
  • RE-START TECHNOLOGY: The RE-START Battery intelligently monitor its status; if it senses over-discharge it will put itself into a sleep mode, yet saves enough energy to allow you to RE-START your vehicle. Simply press the RE-START button on battery.
  • LONGER LIFE: Up to twice the lifecycle of lead/acid, and other Lithium batteries due to full Battery Management system.
  • HI POWER: Up to 2 Times the Cranking Amps of similar sized lead/acid batteries. Better Starting and higher voltage at start-up.
  • ULTRA LIGHTWEIGHT: Up to 70% lighter than equivalent lead/acid battery. Up to 15 lbs in bikes or 40 pounds in some Race Cars. Carbon Fiber costs thousands to lose a pound of weight; with our LiFePO4 battery a few hundred dollars will lose roughly 8-15 pounds and offers better starting and handling!
  • NEW 4 Terminal Design allows easy installation in any vehicle. Fits right or left hand Negative or Positive connections. No more looking for the correct Terminal locations in certain bikes.
  • LOW SELF-DISCHARGE: The RE-START Batteries do not self-discharge like Lead/Acid Batteries. They can hold a charge up to a year provided there are no “Parasitic Drains” (accessories that draw power when bike is off, i.e. alarms, ECUs, GPS, heated grips, and other accessories the vehicle might have).
  • DURABILITY: Our lithium batteries are shock and vibration resistant making them perfect for Racing, and other applications requiring a durable battery.
  • MOUNTING: You can mount our battery in any orientation, there are no liquids to spill or drain out.
  • ENVIRONMENTALLY SAFER BATTERY: No Acid or Heavy Metals such as Lead, Cadmium, or Mercury.

(*Over-Charge protection will not protect from a faulty/old Voltage Regulator spiking Hi-Voltages to Battery. If you have a Pre-1990s Motorcycle replace your voltage regulator; it is over 25 year old and most likely broken by now.)


  • For replacement of all OEM Lead/Acid Batteries of same size.
  • Excellent for every day use in bikes up to 2200cc.
  • Great for extra large, high-performance V-Twin motors.
  • Excellent for Touring Bikes, Adventure Bikes and Bikes where extreme power and larger Amp Hour capacity are needed.
  • Excellent for use in Race Cars of all types including large V-8 Racing Motors up to 700 Horsepower.
  • Not for use with PWC (personal watercraft).

The lithium ATX-20-RS is a direct replacement for these OEM battery sizes:

YTX15
YTX15L
YTX20
YTX20L
YTX20H
YTX20HL
YTX20-BS

GYZ20H
GYZ20L
GYZ20HL


Please Note: For Custom V-Twin applications with Motor sizes over 103 Cubic Inches, and when a higher compression, or modified motor is being used we do not recommend the RE-START version of our Batteries due to the extremely high current draw of these Larger V-Twin Motors.  Please use the following models for Large V-Twin Applications: YTX20,  YTX12-24,  YTX12-20, or V-10.


Use only Lithium specific Motorsport Chargers to charge this battery! Do not use Lead/Acid Chargers.

Cute but not for a super chewer
Color: Green, Color: Green
It’s a super cute toy. My boy loves the squeaker toys and he’s a fast chewer. Unfortunately for him, he tore it up within 24 hours. It’s definitely not for super chewers but he had a good time with it while it lasted!

Bully approved
If he wants something to gnaw on he will sit with it but he doesn't really play with it. Which is probably the point. It's lasted. The ends are the most chewed. Overall great for a chewer!

Surprisingly Durable
Color: Green
Our dog is an aggressive chewer. She has destroyed other toys meant for "aggressive chewers" in less that 6 hours. This toy has lasted 17 days and it's still going. It does have areas were the seam has given way and a very small amount of stuffing has come out. She has "killed" the squeaker. But the toy is still usable. We just played Tug of War this morning. It will not last forever. It is showing it's "age". But the durability is there. I am ordering more.

Durability and lasting period of toy.
Color: Green
I got this toy for our bulldog. He had a hole in it, which will only progress, within minutes. I took it away until I could find out if there is any kind of warranty. The information says this toy is not for aggressive chewers, yet right in the description and the photo of the toy (that way I knew I was looking at the correct toy), it says for the "aggressive chewer". I am disappointed that even though it isn't how they described, it only lasted minutes before there was damage. Not sure if I would buy another product.
