STARMAX LITH12-40 12V 40Ah LiFePO4 Deep Cycle Lithium Battery

SLI40-12 is a 12V 40Ah lithium battery with Bluetooth LiFePO4 technology, also known as Lithium Iron Phosphate.

This battery is designed for high-performance use in all deep cycle applications such as marine, recreational vehicles RV, solar/wind energy systems, off-grid systems, camping, and backup power systems. Due to its popularity in the marine industry, the SLI40-12 is commonly referred to as a deep-cycle lithium marine battery. This 12V 40Ah battery model can also be used to replace standard AGM batteries in the use of floor machines, medical devices, electrical vehicles EVs, and much more.

12V 40Ah lithium battery is engineered with lithium-ion cells offering superior performance and high reliability as they can be used for power storage solutions or as power sources. Unlike traditional Gel and other SLA batteries, they can be fully discharged without loss in longevity. To further enhance safety and performance, our 12V 40V LiFePO4 battery is equipped with an intelligent internal battery management system (BMS), which provides safety features including low-temperature disconnect and over-discharge protection. The SLI40-12 model is fitted with M6 terminals.

Our high-power lithium iron phosphate batteries can withstand up to 2500+ charge/discharge cycles at a depth of discharge of 100%. LiFePO4 batteries have the longest shelf life and can be stored for up to 2 years in any state of charge without the worry of degradation. This makes them exceptional for use in seasonal equipment as they do not require maintenance for long periods of time. This 12V 40Ah lithium battery can be connected in parallel up to 4 units of the same model to create a 12V 80Ah,12V 120Ah, or even 12V 160Ah battery bank. It can also be connected in series of up to 4 units of the same model to create a 24V 40Ah, 36V 40Ah, or even 48V 40Ah battery bank.
