12V 50Ah Sodium ion Battery
PRODUCT INTRODUCTION

Introducing the CFS-NA1250, a robust 12.4V 50Ah lithium iron phosphate battery that offers a superior blend of power, endurance, and safety. This unit provides 620Wh of energy and is engineered for exceptional longevity, supporting more than 3000 cycles at 60% DOD. It ensures high performance with a very low internal resistance and minimal self-discharge. The battery operates efficiently across an extremely wide temperature range, from -50°C to 90°C for discharge, and is protected by an IP67 enclosure against dust and water ingress. Housed in a sturdy ABS case with M8 terminals, it is perfectly suited for demanding applications such as engine starting, solar energy storage, and heavy-duty mobile equipment, offering reliable power wherever it's needed.
