Best Battery for Car Audio System in 2021 - TheVehicleCare (6)

From the house of LifePo4, we introduce you to this high-performance car audio battery, which is one of the most versatile and reliable batteries available on the market today. It’s a high-amp starting battery packed with extraordinary features. Its maintenance-free operation translates into many years of service, making it a must-have car battery for your sound system.

100 Ah LiFePO4 Key Highlights and Benefits

Cutting Edge Specs:At a whopping 1000cc, this 12-volt, 100-hour battery does not require any hardware to work with your sound system. All you need to do is place it on the battery tray, and so you have a separate battery for the car audio. It’s also a low-profile car battery, which means it doesn’t take up much space.

Battery Management System (BMS): The power control board (PCB) has a built-in battery management system, which is the heart of this battery. This system offers protection against short circuits, reverse polarity, Under voltage and overvoltage, and balancing the load and voltage of the individual cells. The BMS also allows you to connect multiple 100 Ah LifePO4 batteries in parallel with each other without the need for external protection.

Circuit Boards: Circuit boards are lined up across the cells to help control pressure, current, and temperature. If, for example, if there is a case of high internal pressure, the plates will respond with an automatic voltage cutoff that will cut off the positive and negative current. These circuit boards also help prevent any damage to the battery due to the shorted cell.

Solid Construction: The 100Ah comes with an ABS housing with the terminals of each cell soldered to a plate to provide a solid ground for electrical and physical connection. In addition to this, each cell has three layers for safety protection, which helps extend this audio battery’s life. The recommended cold-cranking amps for this unit are 1000, making it suitable during winter.

Pros

  • It takes little time to recharge; roughly about 3 hours
  • It can withstands very high charge rates .i.e. 100A
  • This battery does not freeze even in extreme temperatures.
  • It does not need to be fully charged for storage rather it can be stored at any state of charge(SOC)
  • It is lightweight and its weight is almost half of its lead-acid counterparts.

Cons

  • It is not the cheapest option.
  • Not suitable to be used as a cranking battery.
