Features
RE-START Technology
The internal Battery Management System detects over-discharge and automatically enters sleep mode, reserving enough power to start the vehicle.
Simply press the button on the remote to wake it up and start your engine.
Full BMS Protection
Built-in protection against over-charge, over-discharge, short-circuits, and over-heat, while maintaining optimal cell balance for maximum battery life.
Significant Weight Reduction
Reduces weight by approximately 16–27 kg compared to standard H7 lead-acid batteries.
Provides a noticeable improvement in vehicle handling, braking, and acceleration.
High Cranking Power
Up to 2000 Cranking Amps ensures reliable starting for large-displacement, high-compression, turbocharged, and track-oriented engines.
Direct Bolt-In Replacement
Fully compatible with stock sizing. No modifications or additional battery trays are required.
Practical Benefits
• Improved cold-weather starting
• Stable idling voltage
• Improved handling due to weight savings
• Excellent for high-output vehicles and ECU-controlled systems

Notes
• Use only a LiFePO4-compatible charger (do not use a standard lead-acid charger).
• Periodically check battery status during long-term storage.
• If your vehicle has a high parasitic draw (e.g., many constant-power accessories), select a model with higher capacity.
Before You Order
〇 Import Taxes
Shafutoya handles the payment of import taxes for all orders, so you will not be charged anything beyond the total amount paid at checkout.
〇Compatibility Check
Our product database is based on North American (USDM) vehicle specifications. Please verify compatibility with your Japanese-market (JDM) vehicle before ordering. (Feel free to contact us if you are unsure; our support team will assist you.)
We cannot accept returns due to incompatibility if a product was ordered without verifying fitment first.
Please note that even if a product appears after filtering by year, make, and model on our site, it does not guarantee a direct, modification-free fit for Japanese-market vehicles.
All product descriptions are machine-translated; please contact us if anything is unclear before ordering.
○ Shipping
Shipping costs are paid at checkout. Quotes are automatically calculated based on your shipping address. In rare cases, the automated calculation for large items like body parts may significantly differ from actual shipping costs; we will contact you via email if such an adjustment is required.
All products are shipped internationally from our U.S. warehouse. Please allow 7–14 days for international delivery. If you are in a rush, please inquire about delivery times beforehand. All items are shipped via air freight, not sea freight.
○ Japanese Vehicle Inspection (Shaken)
Our products are designed and manufactured outside of Japan and are not compliant with "Japanese vehicle inspection" regulations. We cannot provide structural strength documentation. Therefore, all parts are sold for use on circuits, private property, or off-road use only, and installation/use is at your own risk.
○ Warranty
Please inspect your items immediately upon arrival. As all goods are shipped internationally, packaging and products may occasionally suffer shipping damage. We offer returns, refunds, or replacements for damaged, defective, or incorrect items only if reported within 7 days of receipt. All warranty claims must be processed directly through us; we do not provide support through other companies or domestic agencies in Japan.
