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.

A perfect natural glam mascara
Color: PLUM TWILIGHT, Size: 0.24 Fl Oz (Pack of 1)
I have been searching for my ultimate, every day mascara for at least 10 years & I actually tried this one about 4 or 5 years ago (not in this shade though) and I remember it being a strong like at the time but not “the one”. Buuut this might be the one. Went on smoothly with minimal clumping. Elongated and curved my lashes upwards without using an eyelash curler. Held up for 9 hours in humid, sticky conditions and is still going strong. No flaking, smudging or transfer. I do wish the brush was different, or had longer bristles at least, but not enough to dock a star over. The plum shade is gorgeous and veers toward black in some lighting but has just enough color to enhance the eyes. It didn’t add a ton of volume, but enough to be noticeable and I actually prefer that because I have sensory issues with my eyes and that is why I sadly can’t do falsies. All in all, this is a 5 star, every day, natural glam mascara and now I want to try the green.

My Favorite Face Mask for Hydrated, Glowing Skin
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve tried a lot of face masks over the years, but the BIODANCE Bio-Collagen Real Deep Mask has easily become my favorite. Every time I use it, my skin feels incredibly hydrated, smooth, and refreshed, and the results last much longer than I expected from a single mask treatment. One of the things I love most about this mask is how deeply moisturizing it is. After wearing it overnight, my skin looks noticeably plumper and feels soft and nourished. Instead of just giving a temporary boost, I’ve found that the healthy glow lasts well beyond the next day. In my experience, my skin maintained a radiant, hydrated appearance for nearly two weeks after use, which is something I haven’t experienced with many other masks. The hydrogel material feels comfortable on the skin and stays in place well throughout the night. When I remove it in the morning, my skin looks brighter, more refreshed, and noticeably more hydrated. I appreciate that this mask feels like a true self-care treatment rather than just another skincare step. Whether I’m preparing for a special event or simply giving my skin some extra attention, this is the mask I consistently reach for. The fact that it comes in a multi-pack makes it even better because I always like having one available when my skin needs a boost. Overall, this is one of the few skincare products that I continue to repurchase because I genuinely notice a difference. If you’re looking for a mask that delivers intense hydration, plumping benefits, and a beautiful long-lasting glow, I highly recommend giving this one a try.I’m

Instant Glass Skin!
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve tried SO many sheet masks and this collagen one is genuinely one of the best. My skin looked insanely hydrated, smooth, and glowy after just one use. It fit my face really well, stayed soaked the entire time, and didn’t leave that sticky feeling afterward. The next morning my skin still felt soft and looked brighter. Perfect before events or whenever your skin needs a reset. Definitely repurchasing!!

Nice mask! Caviar
Scent: PDRN, Size: 4 Count (Pack of 1), Scent: PDRN, Size: 4 Count (Pack of 1)
The first 3 pictures were taken after the first hour and a half. The second 3 pictures were taken at 2 hours. The mask had a hard time dissolving underneath my eyes and around my chin area mostly but everywhere else it hardened within the first hour or so. I will try to wear it for longer than 2 hours next time. To see if that changes, but my skin feels really nice right now. It's a little sticky, but it looks healthy and has a nice glow. Application is easy. I love that its separated into 2 parts. Doesn't fit well around the nose between the eyes and doesn't cover my entire face but its a great mask. I tried the caviar one this time. I have the collagen ones as well but these have better reviews. They seem to work effectively, for a nice glow and self pamper session.
