Shipping time varies depending on the product and your location. Generally, delivery takes 1-7 business days, and domestic shipping typically takes 2-3 business days.
All in-stock orders ship within 1-2 business days, and orders placed on the same day are usually shipped on the same day.
If the product is a pre-order or out of stock, it will require a longer shipping time. We will inform you of this at checkout or after your purchase.

Select "Warranty Claim" in the contact form type. Include your order number, product model, purchase date, and any photos of labels or issues. If you have not received warranty service, please register for warranty first.

Please provide the product model and system voltage, controller/model, charger model, temperature, symptoms, and any fault codes. Photos of wiring also help.

You can obtain the necessary product manuals, video tutorials, and more information in our "User Guide" center. If you have any other questions, please clearly describe your problem via email or form, and we will handle it for you as soon as possible.

Start with voltage, usable energy, discharge current, and the space you have for installation. A 48V 105Ah lithium battery suits many EZGO, Club Car, Yamaha, and ICON upgrades, while a 48V 150Ah lithium battery gives more range for hills, heavy loads, or 4–6 passenger carts. RV, marine, home storage, and forklift setups should be matched by watt-hours, inverter load, charger type, and daily runtime.

Match the battery voltage first, then check tray size, cable position, charger type, controller label, and accessory load. Golf carts such as Club Car Precedent, EZGO TXT/RXV, Yamaha Drive/Drive2, and ICON usually need a 36V, 48V, or 72V system match, not just a similar battery shape.

Check that the charger is LiFePO4-compatible, the terminals are tight, the main fuse is intact, and the battery is not in low-voltage or temperature protection. Read the SOC, voltage, current, temperature, and protection status from the LCD or Vatrer app if your model supports monitoring. Note what happened before the issue appeared, such as charging overnight, climbing hills, adding accessories, or storing the battery below 32°F.

The Vatrer LiFePO4 lithium batteries can be wired in series or parallel when the product manual supports it. Use identical Vatrer batteries with the same Ah rating, BMS current, brand, and purchase timing.
