^{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. 680 CA, 20 Ah (Pb Eq).}

^{(Please note if you use older bikes from the mid 1990's and earlier you must update the charging systems to a modern voltage regulator. Damaged voltage regulators can over charge and damage lithium batteries)}

Due to their excessively high current draw, the restart & heavy duty series of batteries are not suitable for bikes with large, modified or custom V Twin engines

RE-START Series: FIRST Batteries with Built-In Jump-Starting!

^{OEM Size Lithium Battery (Direct Replacement)}

^{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… 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.}

^{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. Additionally it features our exclusive RE-START feature so you won’t get stranded with a dead battery.}

FEATURES

^{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.)}

Use only Lithium specific Chargers to charge this battery!

16.1.19. car honda civic import fd2 type r 2000cc. occ use road car. lads at antigrav [ag] were a fab bunch. spent ages chewing the fat as i work occ in southend so bought in person- real car nuts ). bought battery end october 2018 and left alone pre fitting til today 3 months later. weight 1.5 lbs [!!!] vs @ 23.5 lbs of bosch s4022-my main reason [car weight reduction] esp in very front of car. battery terminals' small 'locknut block' and bolts/ washers on it mean ideally it should be fitted by autoelectrician...my bosch battery failure through non use for @ 3/52 [not uncommon, couldn't revitalise with a ring smart charger which usually works] meant i fitted myself today using a cut up ctek 'washer end' electrical lead from spares in the garage with other end of it wires wrapped around bolts of the small japanese terminals of car [it'll do for now]. +ve terminal still has protective plastic block around it. didn't use 'restart' button. fired up first time quickly no probs though not with a 'forceful/ authoritative' start if that makes sense. drove 45 mins with lights and ac , radio and will restart tomorrow for work. big space for the bosch ['hybrid', usa, battery relocation kit holder due to air filter pipe where oe battery sits] has temporarily been filled. 4/5 as i need to see what extended non use of car does re its ability not to fail [like lead acid ones++], frozen weather start [coming soon...], ability to charge from my car and reliability. happy camper so far.
Note for ag lads - consider selling a conversion kit e.g. from japanese terminals to yours eg 2 male 'cones' simulating the oe battery terminals connected to 'washer end' leads to your battery. Cheers, Jamal
