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.

Great look and very powerful - consider what your wanting to froth/mix - may be too powerful
Color: Lux White, Size: Rechargeable Z1 Motor Max
It's a great frother - but more for large drinks. Very powerful, even on the low speed. I returned it because I want something to mix my collagen and creamer in my coffee. The first time I turned it on it shot half the coffee out of the cup - very powerful. It has a great look, sleek and fits easy in the hand - but for what I needed, two powerful. It would have been nice to have a fully adjustable speed wand like my replaceable battery powered frother.

Powerful, rechargeable battery, easy to use & clean
Color: Lux Absolute Silver, Size: Rechargeable Z1 Motor Max
2 speeds, easy to change back and forth to different speeds with one click , easily blends 1/4 cup protein powder in 12 oz milk on low speed. Easy to clean: Stick blending wand in tall glass with warm water + dish soap, turn on low speed to clean easily (don’t stick the part that holds the battery in glass). Also of note, chosen by Americas Test Kitchen as best milk frother but I use it to make protein shakes.

Works great on bullet coffee!!
Color: Lux Alpha Black, Size: Rechargeable Z1 Motor Max
I am really pleased with this frother! Frothers I have used in the past didn’t mix my decaf coffee, 2% milk, and MCT oil as thoroughly as I like (oil and coffee separated). This frother blends everything AND I get a nice layer of frothy milk on top!!! Charge lasts a long and the froth can be submerged all the way up to the button!!!

Powerful, Versatile & So Easy to Use!
Color: Black
This immersion blender exceeded my expectations! The 1100W motor is super powerful and blends everything smoothly-from soups to smoothies—in seconds. I love the trigger speed control because it gives me full control depending on the texture I want. The attachments are a huge bonus-the whisk works great for eggs and batters, and the milk frother is perfect for my morning coffee. It's lightweight, easy to handle, and super convenient compared to using a bulky blender. Cleanup is quick, which is a big plus for everyday use. Overall, a versatile and reliable kitchen tool that makes cooking so much easier!

Quiet, powerful, and very easy to use
Color: Black, Color: Black
Very convenient and stylish milk frother. I use it every day for coffee and matcha — the foam becomes thick in just a few seconds. It works quietly, holds a charge well, and the wireless design with USB charging is very convenient. The handle is lightweight and comfortable to hold. Great value for making café-style drinks at home.
