Return Shipping Cost
WattCycle Pays For Return Shipping
WattCycle will pay for the cost of return shipping if the reason for the return was the result of our error.
Examples of instances may include:
Item arrived defective and cannot be fixed with a replacement part.
We shipped out the wrong item.
We shipped it to the wrong address.
We shipped a duplicate order.
Item malfunctioned during the 30 day returns period. (The customer should install and operate the item properly per the product manual instruction.)
Attention
For items that arrive damaged or are defective, the customer MUST provide videos or photos to support the claim that the item arrived damaged or is malfunctioning. If a customer refuses to or fails to provide videos or photos of a claimed malfunctioning/damaged item, this return will be treated as “buyer’s remorse” and the customer is solely responsible for shipping it back. Once we have received the approved returned item, we will review its condition. If the item is found to be defective, we will issue a refund within 3 working days.

PRODUCT DESCRIPTION
Portable Battery Design: WattCycle 12V 8Ah LiFePO4 battery is smaller (L152 x W66 x H96mm) and lighter (0.95kg) than a traditional 12V 8Ah lead-acid battery (AGM battery). Its energy density reaches 107.79Wh/kg, while the 12V 8Ah lead-acid battery (AGM battery) achieves only 22.02Wh/kg.
EV-Grade A+ LiFePO4 Cells: WattCycle 12V 8Ah LiFePO4 battery is equipped with high-quality EV-grade A+ cells, guaranteeing a lifespan of over 5000+ cycles and up to 10 years. The LiFePO4 cells make the lithium battery more compact, which can enhance the working efficiency of the battery cell and ensure that there will not be any accidental situation such as power outage in the process of using.
Comprehensive BMS Protection: WattCycle 12V 8Ah LiFePO4 battery features an 8A battery management system (BMS) that provides protection against over-voltage, over-current, deep discharge, short circuits, overcharging, and extreme temperatures (high/low). It also enables cell balancing.
IP67 Dust & Water Resistant: WattCycle 12V deep cycle LiFePO4 batteries are designed with a compact case that is IP67 rated for dust and water resistance. The high impact resistance battery case is made of non-conductive ABS plastic, which has strong resistance to impact, shock, chemicals, and heat. The insulating material ensures that there is no leakage of electricity during use. It can be used normally, even on rainy days, but you need to be careful that the positive and negative poles do not get wet.
Up to 1638.4Wh Energy Solution: WattCycle 12V deep cycle LiFePO4 batteries support up to 4 in series and 4 in parallel configurations. Using the 16 WattCycle 12V 8Ah LiFePO4 batteries, a 48V 32Ah battery system can be built, delivering a continuous charge/discharge current of 32A, massive energy storage of 1638.4Wh, and an output power of 1638.4W.
Safer & More Environmentally Friendly: Compared with traditional lead-acid batteries, WattCycle 12V 8Ah small capacity battery is made of the latest lithium-ion technology. The battery doesn't contain any heavy metal elements; it's safer and more environmentally friendly.
Versatile Applications: Ideal for small devices such as fish finders, electric fishing reels, fishing gear, camping equipment, amateur radio equipment, and motorized toy cars.
