Epoch Batteries takes immense pride in offering the finest lithium iron phosphate (LiFePO4) batteries specially crafted for marine applications. Our batteries have undergone meticulous design and engineering to meet the exacting demands of the marine industry, delivering exceptional performance, safety, and durability.

One of the standout features of our LiFePO4 batteries is their outstanding safety profile. Equipped with built-in protection circuits, they effectively prevent overcharging and over-discharging, significantly reducing the risk of fires or explosions. Additionally, our batteries exhibit high thermal stability, allowing them to withstand elevated temperatures without igniting. These qualities make them the ideal choice for marine applications where safety is paramount.

Another notable advantage of our LiFePO4 batteries is their extended lifespan. These batteries can endure up to 3,500 cycles at 80% depth of discharge, far surpassing the longevity of traditional lead-acid batteries and other lithium-ion counterparts. As a result, they require less frequent replacement, ultimately saving our customers both time and money in the long term.

Our LiFePO4 batteries also offer a superior energy density compared to lead-acid batteries, enabling them to store more energy in a smaller space. This attribute proves invaluable in the often space-constrained marine environment. Additionally, their reduced weight simplifies handling and installation, enhancing user convenience.

With a significantly broader operating temperature range than lead-acid batteries, our LiFePO4 batteries excel in diverse environmental conditions. They can be discharged to lower levels without incurring damage, allowing for more efficient utilization.

Our LiFePO4 batteries also feature a faster charging time than lead-acid batteries, facilitating quicker recharges and more frequent usage. Moreover, they boast a low self-discharge rate, ensuring they can be stored for extended periods without losing their charge. This is particularly advantageous for marine applications where the battery may go unused for extended periods.

At Epoch Batteries, our unwavering commitment is to provide customers with the highest quality products and services. We are confident that our LiFePO4 batteries represent the optimal choice for marine applications, and we back this conviction with a comprehensive warranty, affirming our dedication to customer satisfaction.
