Super safe 32140 10ah sodium ion battery for two wheeler
Main Feature of CSiT 32140 sodium ion battery:
● High discharge rate: 5C continuous discharge rate and 15C pulse discharge rate, suitable for the application of e-bike, e-motorcycle, low speed car,etc.
● High safety. The electrode materials of sodium-ion batteries possess excellent thermal stability, which prevents the batteries from catching fire or exploding when subjected to extreme tests such as overcharging, over-discharging, short-circuiting, and nail penetration.This stability is a key advantage of sodium-ion batteries, ensuring their safety under various extreme conditions
● No over discharge effect. Sodium ion battery could be discharged to 0V without any over discharge effect, which allows to discharge it to 0V during shipment to avid safety issue.
● Fast charge/discharge. CSiT sodium ion battery can be charged at max 3C-4C , and discharged at 3C, 5C, 20C, 75C according to the battery cell we provide.
● Long cycle life. Our sodium ion battery cycle life is over 3000 times @ 70% DOD.
