Sodium-ion Battery Module 12V40Ah
H8 / PL4-40Ah
Characteristics & Advantages of Sodium-ion Batteries
LOW POWER START STOP
Sodium-ion batteries can start the vehicle even when it is low on power.
ULTRA-LOW-TEMPERATURE STARTING
Sodium-ion batteries enable vehicle starting in extreme conditions down to -40℃.
ULTRA-LONG STANDBY MAINTENANCE
Sodium-ion batteries can be discharged to 0V and still be used after recharging without affecting their service life.
HIGH SAFETY
Sodium-ion batteries are non-flammable and have better safety performance than lead-acid batteries.
LOW COST
Sodium is abundant and inexpensive, which helps reduce battery costs.
LONG CYCLE LIFE
Sodium-ion batteries boast extended cycle life, which can last as long as the car.
ENVIRONMENTALLY FRIENDLY
Sodium-ion batteries contain no harmful substances and are environmentally friendly, in line with the concept of sustainable development.
