Original 32700 4700mAh Sodium Ion Battery
Original 32700 4700mAh sodium ion battery with 3C discharge rate
ain Feature of this 32700 sodium ion batteries:
* Nominal voltage is 3.1V, nominal capacity is 4700mAh.
* Support 3C max continous discharge 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 1500 times,which is much longer than NCM material lithium ion battery.
* Cost saving. The cost of SOB can be lower than lithium ion battery in future.
* 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 32700 na-ion batteries to replace 32700 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 90% capacity retention rate.
Q: How can I place battery order for battery packs?
A: We will check your battery request in details and provide our proposal, once confirmed, we will provide PI for you to arrange payment to proceed with sample order first, once sample confirmed, we will prepare spec data sheet for your record, and send sales contract for you to sign and arrange payment, then we will proceed with mass production.
Q: What’s the payment terms?
A: For battery cells and energy storage battery, we normally accept 30% deposit, balance to be paid before shipment for the first cooperation, if you have any special payment terms request after that, we will send your document to our finical department to confirm.
Q: Which brand of inverter does your stacked energy storage battery compatible with?
A: Our battery is compatible with most mainstream brands in the market, such as PACE / PYLON / Growatt / Voltronic / Schneider / Luxpowertek / WOW / VISION / GoodWe / SMA / Sorotec / STUDER / SofarSolar / GINLONG / MUST / Victron，etc.
This original 32700 4700mAh sodium ion battery with 3C discharge rate , support -40℃ low temperature discharge temperature, much safer than lithium ion materail.
