These are the world's first motorsport lithium ion batteries with built-in RE-START technology & Battery Management System (BMS). The 4-terminal design means you have dual polarity for more flexibility with installation location.
The NEW Antigravity ATX20-RS battery is built with our groundbreaking RE-START Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! This is a HI-Power, lightweight lithium replacement battery for the heavy YTX-20 Series Lead/Acid battery.
The new Antigravity 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 Antigravity ATX20-RS (Antigravity ATX20 Restart Battery) 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.
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. As with most all our batteries, you can easily bolt on our Automotive Terminal Adapters for use in high performance automotive applications.
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.
Antigravity ATX20-RS (Antigravity ATX20 Restart Battery)
Features:
- 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. (A Remote RE-START Button will soon be Available so you can activate the RE-START feature without accessing 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 years old and most likely broken by now.

***USE A LITHIUM ION CHARGER TO AVOID DAMAGING THE BATTERY***
Please Note:
- For custom V-twin applications over 103 cubic inches or when a higher compression, modified motor is being used we do not recommend RE-START batteries due to the extremely high current draw of larger V-twin motors.
- If you own an older classic bike from mid 1980s and earlier you must update the charging system to a modern solid-state voltage regulator. Damaged or excessively old voltage regulators can over-charge and damage lithium batteries and cause smoking and melting of battery. This is NOT a fault of the battery!
Please use the following models for large V-twin applications: YTX20, YTX12-24, YTX12-20, or V-10.
