High Safety Yinlong Brand New Class A LTO Battery 2.3V 40ah Lithium
Titanate Battery
The lithium titanate battery is a type of rechargeable battery
which is also called LTO Battery, which has the advantage of being
faster to charge than other lithium-ion batteries and a long cycle
of life. The discharge rate of Titanate batteries is very high, as
much as 10C.
A disadvantage of lithium titanate batteries is that they have a
lower inherent voltage (2.4 V), which leads to lower specific
energy of about 30 = 110Wh/kg than conventional lithium ion battery
technologies (which have an inherent voltage of 3.7 V).

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
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.
