We shipped 4 pcs of 3.2V 400Ah Thunder Sky Winston LiFeYPO4 batteries to Canada by FedEx recently and provided a 3-year warranty and door-to-door service.
These 400Ah Winston LiFePO4 batteries can be easily assembled into a 12V 400Ah 5 kWh LiFePO4 battery pack for a home solar system using connectors and busbars. The maximum discharge and charge current of each battery is up to 3C (1200A), with an ultra-long cycle life of 5000 cycles (80% DOD). Every battery we ship is tested, so you receive cells that are tested, guaranteed, and brand new Grade A.
Winston LiFePO4 batteries are an excellent option for 12V systems because four cells in series provide a voltage equivalent to a lead-acid battery, and they can be widely used in EVs, RVs, energy storage systems, solar systems, etc.
Our company, BESS, supplies high-quality CALB, CATL, Winston, and Sinopoly lithium batteries to businesses or personal DIY projects. If you have any requirements, please feel free to contact us, and we will provide you with quality batteries and superior service.
