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.

What is LTO/Lithium titanate battery?

• Lithium titanate battery(LTO) is a kind of lithium titanate used as a negative electrode material for lithium ion batteries. It can be combined with lithium manganate,NCM materials or lithium iron phosphate to form a 2.4V or 1.9V lithium ion secondary battery.
• LTO battery is deep cycle with more than 25000 times.
• LTO lithium battery is one of the best options for solar energy system
• It's for street lamp,home power wall,solar system etc

Lithium battery won't lose capacity at extremely low temperature

LITHIUM TITANATE(LTO)

Spinel structure/Zero strain material

Lithium titanate has a stable 3D crystal structure,The material structure hardly changes in discharging&charging.
Compared to lithium battery with graphite as the negative electrode,LTO hardly results in SEI with poor stability that
happens on LFP,Avoiding thermal runaway caused by SEI during high-temperature decomposition, resulting in battery
fire and explosion.

Lithium titanate batteries have a higher potential for lithium metal,no lithium crystal occured,safer and better stability.
It's able to charge&discharge in high rate due to 3D lithium iion transist channel.Fully charge and discharge within the
range of -50 ° C extreme low temperature to 60 ° C ultra-high temperature.

Delithiation,LTO(volume change rate ± 3%),25000 times life

Frequent delithiation,Graphite volume increases(volume change rate ± 3%),reducing life cycles
