About Rock-12-120 Bluetooth lithium battery
The Rock-12-100 lithium battery is safe and reliable whilst being small and lightweight, with a long life and fast charging. Comparing the Rock-12-120 lithium battery with similar batteries, the volume and weight are around a third and a half respectively than that of ordinary lead-acid batteries. The build in battery management system(BMS) provides multiple protection: over-charge, over-discharge, over-current and over temperature. The Rock-12-120 lithium battery will last at least 2000 full cycles before minimal performance changes. This means it can last up to seven years, depending on the frequency of use. It can also be charged and discharged under high current without affecting its expected lifespan. The Rock-12-120 lithium battery can be used with solar inverter, vehicles, electricity grid and many other charging methods. It is very suitable for use in various vehicles, such as electric boats, caravans, RVs and so on.
The Rock-12-120 lithium battery support 100A continuously discharge. Customer can parallel up to 4 of them in parallel, to make a 12v480Ahead system. The maximum continuously discharge rate will be 400A in 4 parallel setups. Customer can put up to 4 of them in series, to make a 48v120Ah system. The maximum continuously discharge rate will be 100A in 4 setups.

Lithium Iron Phosphate (LiFePO4) batteries have several advantages that make them a popular choice for various applications, particularly in comparison to other types of lithium-ion batteries like lithium cobalt oxide (LiCoO2) or nickel-cadmium (NiCd) batteries. Some of the key advantages of LiFePO4 batteries include: Safety: LiFePO4 batteries are known for their excellent thermal and chemical stability. They are less prone to thermal runaway or overheating, making them safer than some other lithium-ion battery chemistries.
Long cycle life: LiFePO4 batteries have a long cycle life, typically rated for thousands of charge and discharge cycles, which makes them suitable for applications where durability and longevity are essential, such as in renewable energy systems and electric vehicles.
High energy density: LiFePO4 batteries have a relatively high energy density, which means they can store a significant amount of energy in a compact space. This makes them suitable for portable electronic devices and electric vehicles.
Fast charging: LiFePO4 batteries can accept high charge and discharge currents, enabling faster charging and discharging capabilities. This is advantageous in applications where quick power delivery is required.
Wide operating temperature range: LiFePO4 batteries can operate effectively in a wide temperature range, making them suitable for both extreme cold and hot environments.
Low self-discharge rate: LiFePO4 batteries have a lower self-discharge rate compared to some other battery chemistries, which means they can hold their charge for longer periods when not in use.
Environmental friendliness: LiFePO4 batteries are considered more environmentally friendly compared to other lithium-ion battery types because they contain no toxic heavy metals like cobalt and have a lower risk of hazardous materials leaking into the environment.
Low maintenance: LiFePO4 batteries require minimal maintenance compared to lead-acid batteries, as they don't need regular electrolyte top-ups or equalization charging.
High discharging efficiency: LiFePO4 batteries have a high discharging efficiency, meaning they can deliver a higher percentage of their stored energy without significant voltage drops, making them efficient for various applications.
Versatility: LiFePO4 batteries can be used in a wide range of applications, from small consumer electronics to large-scale energy storage systems and electric vehicles.
