CSIT Wholesale Rechargeable 26700 3.1v 3200mah Energy Storage Sodium Ion Battery
Main Feature of this 3400mah sodium-ion battery:
* Nominal voltage is 3.1V, nominal capacity is 3200mAh.
* Support 3C max continous discharge current and 9C peak current.
* Super fast charge, this sodium-ion battery fast charge current is 1C ,but if you need, we can make it to bare max 3C~4C charging current.
* Support -40℃ low temperature discharge.
* Long cycle life. CSIT cylinder sodium-ion battery cycle life is over 2000 times,which is much longer than NCM material lithium ion battery.
* Cost saving. The cost of soium ion battery can be lower than lithium ion battery in future because the storage capacity of sodium far exceeds that of lithium.
* Good safety performance, it’s much safer than lithium ion battery material, it won’t explode even puncture it with a needle.
* Customized. OEM/ODM request are warmly welcome.

Why use 3400mAh sodium-ion battery to replace 3400mAh Li-ion batteries?
* High safety. Na-ion batteries offer higher safety than lithium-ion batteries, it won’t explode even you prick it with a needle.
* Fast charging performance. Comparing with lithium-ion batteries, na-ion batteries is with better fast charging performance, you can charge it with 3C current, which means the battery can be fully charged within 20 minutes.
* Great low temperature performance. Sodium-ion battery could be charged at -40 ℃ and keep 80% capacity retention rate.
* Cost saving. The cost of soium ion battery can be lower than lithium ion battery in future because the storage capacity of sodium far exceeds that of lithium.
