Description

Never again worry about getting stranded with a dead battery! 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…

The new ATX20-RS is a super lightweight and high-power Lithium-Ion replacement battery for the heavy lead/acid YTX20 battery found in many Motorcycles and Powersport Vehicles.

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.

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.

Additional Restart-Remote part (Item #985111) sold separately for Antigravity RE-START (RS) Powersport Batteries with jump-starting built-in. Simply plug this accessory into your Battery's charging cable to remotely awaken the RE-START Battery with no need to remove the seat or a fairing to get to the Battery.

Features:

  • YTX20 case size: 6.89 x 3.4 x 5.12 inches (L x W x H)
  • 680 Cranking Amps
  • 20 Amp Hours (PbEq)/ 10Ah (Actual)
  • 3.8 lbs
  • Advanced Lithium Battery on the market
  • World's First Battery with Built-in Jump Starting, 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 way, 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.)

Best Uses:

  • 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)

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: AG-YTX-20, AG-YTX-12-24, AG-YTX-12-20, or AG-V-10. Use only lithium specific motorsport chargers to charge this battery! Do not use lead/acid chargers. Can only be charged with lithium chargers, charging at a minimum rate of 4 Amps

Rated 4 out of 5 by from Never going back to lead acid I replaced my lead acid battery because I don’t have a garage and haven’t been maintaining them over winter, shortening their life. I’m hoping the high cost of a lithium battery will pay off for me. I’m the meantime, I’ve already used the “restart” feature, which is fantastic. My only complaint is that Antigravity uses different dimensions than lead batteries do, so I had to modify my bike to make the battery fit.

Questions

Would a 2008 screamin eagle dyna (fxdse2) with the 110ci and a custom tune be considered a custom engine over 103ci or is this battery suitable for it? It seems to eat batteries like crazy and looking to be done with acid batteries.
