Welcome to purchase 12v 20ah Lithium batteries! Our 12v 20ah Lithium is a LiFePO4 battery or LFP battery. These batteries have long use-time, high safety, low weight, and fast charging. Thanks to the low self-discharge rate (<3% per month), these batteries can be stored for many years without maintenance.
To make our batteries have higher safety, we adopt cutting-edge technology and the BMS system to ensure that the batteries remain safe and stable during long-term use. These 12v 20ah LiFePO4 batteries are not the cheapest on the market, but they must be more cost-effective than other types of batteries in the long run.
Would you be confused when purchasing 12v 20ah Lithium in China? Because China has so many suppliers and manufacturers. Now you meet XD Battery. You need no confusion anymore! We are founded in 2006. With advanced machines and factories, we accept all types of customized orders. Our OEM and ODM Lithium batteries have TUV UL CE CSA CEC JET certifications.
