Antigravity VTX-20 16V Lithium Battery
The VTX-20 is an ultra-lightweight, high-power lithium battery designed for race vehicles using 16V electrical systems. Despite its compact case, which matches the YTX12 size standard, it provides 500 Cranking Amps of starting power and an actual capacity of 12.5Ah (200Wh).
Weighing only approx. 2.3kg, it offers a significant weight reduction compared to traditional lead-acid batteries.
Its 16.5V design, specialized for strong spark and stable voltage supply required by racing ignitions and high-RPM/high-compression engines, delivers reliable starting performance and throttle response.
Specifications
Case size (YTX12 compatible): Approx. 150 × 87 × 130 mm
Voltage: 16.5V (for 16V racing systems)
Starting performance: 500 Cranking Amps
Capacity: 25Ah (lead-acid equivalent) / Actual capacity 12.5Ah / 200Wh
Weight: Approx. 2.34kg
Terminals: Large all-brass terminals
Mounting: Multi-directional
Features
Despite its compact size, it secures the high ignition voltage and starting torque necessary for 16V race vehicles.
The lithium structure allows for a weight reduction of up to approx. 12.7kg, directly improving acceleration, braking, and steering response.
It maintains cell balance during long-term storage and offers up to 1 year of self-discharge protection when no electrical load is present.
Features high vibration resistance, making it suitable for rigorous environments like drag racing and circuit driving.
Compatibility and Use Conditions
Exclusively for vehicles using a 16V racing electrical system.
For drag racing, road racing, and circuit vehicles.
Not recommended for passenger cars, street vehicles, or daily drivers (incompatible with standard charging systems).
A 16V-compatible charger (or regulator) is required as necessary.
Recommended Applications
Race-only vehicles (NA / Turbo / High-compression engines)
Competition vehicles where weight reduction is the top priority
Motorsports applications using 16V coils, CDIs, or fuel systems
Before Placing an Order
〇 Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether or not they can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us with any questions before placing your order.
○ Regarding Delivery
Shipping costs are paid at the time of settlement. An estimate for shipping can be calculated automatically by entering your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us in advance to check the delivery date. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese vehicle inspection standards" at all, and we cannot provide strength calculation sheets or similar documentation for Japanese vehicle inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packing box or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
