The Antigravity AT7B-BS RE-START Lithium Battery is an ultra-lightweight, high-cranking lithium battery that can replace the OEM YT7B-BS specification battery. It is specifically designed as a replacement for the factory lead-acid batteries found in vehicles like the Ducati Panigale.
Its standout feature is the RE-START (restart) function, which automatically switches to power-save mode when the battery is about to die, reserving power for a "restart." If the battery ever goes dead, you can simply press the button on top of the battery case to crank the engine and start it again. You will never be stranded by a sudden battery failure.
Furthermore, it is equipped with a full BMS (Battery Management System), which automatically controls over-discharge, over-charge, thermal protection, and cell balancing, significantly improving safety and lifespan.
It weighs only approx. 0.68 kg, achieving up to 70% weight reduction compared to lead-acid batteries. This improves the motorcycle's agility, providing clear benefits in acceleration, braking, and handling.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
Our entire product database is based on North American (USDM) vehicles; please confirm compatibility with Japanese (JDM) vehicles 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 investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and model using the tabs on our home page, this does not necessarily mean they are compatible with Japanese models without modification.
All products have been translated into Japanese using translation software. Due to potentially confusing phrasing, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us to confirm the delivery date in advance. All products are shipped via air freight. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Generally, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. 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 cases of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support is handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
