Its 72V 20AH LiFePO4 composition ensures stability and safety, making it a good choice for users who prioritize safe, consistent performance.

Another plus is the battery's high discharge current, supporting motors up to 1800W, making it versatile for different types of electric vehicles. However, the battery is relatively heavy and might add significant weight to your ebike setup. Also, it’s important to ensure that its specific size (7.9*8.7*4.7 inches) fits your battery case before purchasing.
