Car Audio 12V Lifepo4 Battery 22ah Prismatic Cell For Yacht Boat Caravan

Car audio 12V Lifepo4 battery 22ah prismatic cell

Reasons why car audio batteries require high current

1.Music is not a constant signal, it is full of instantaneous explosive power, such as the tapping of bass drums, explosions, and so on. These moments require audio amplifiers to provide enormous power (current) in a very short amount of time to drive speakers and reproduce impactful sound.

2.High power speakers require enormous energy, and energy (power)=voltage x current. To achieve high power with a fixed voltage, it is necessary to use a large current.

The standard voltage for the electrical system is usually fixed 12V,To achieve high power, it is necessary to increase the current.

If you want the peak power of your audio system to reach 1000W

• I = P / V = 1000W / 12V ≈ 83.3A

• This means that at peak output, your audio system needs to draw over 83A of current from the battery and generator! This is only a rough estimate, and in reality, due to issues such as amplifier efficiency, the current may be higher.

3.High performance car audio systems typically use low impedance speakers, commonly 4 Ω, 2 Ω, or even lower.

Ohm's Law: I=V/R

In the case of a fixed voltage V, the smaller the resistance R, the larger the current I.

Driving a 2 Ω speaker requires twice the current as driving a 4 Ω speaker at the same voltage.

Battery cell IR

Peak 20C discharge,it's excellent for car audio battery.

Compared to LTO,LifePO4 battery has higher rated voltage 3.2V,max 3.65V.

4S for a 12V battery,for LTO it needs 6 pcs cells.

LiFePO4 battery is cheaper cost than LTO.

It is a 22ah LFP prismatic cells,small dimension allows for various installation space by limitation.like E-motorcyle,E-bike,rickshaw,caravan,boat etc.

5C constant discharge for fastly start up,speed up,let vehicles have excellent climbing and acceleration abilities.

High CCA as a starting battery for race car,motorcycle,vehicle,truk etc
