CSIT Cylindrical 18650 Sodium-Ion Batteries for 3C Digital Products / Power Tools / ESS
Main Feature of this sodium-ion battery:
*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.
Sodium-ion Battery,which is also a kind of rechargeable battery,very similar with lithium ion battery,but the cost is only about a half.It has super fast charging function,and not easy to explode.
CSIT sodium-ion battery including cylindrical and prismatic type,supports 3-4C fast charging;-20℃charging,and-40℃discharging;There’s no fire or explosion under the following circumstances:the experimental environment rises to 130℃±2℃and maintains this temperature for 30min;the extrusion voltage reaches 0V or the deformation amount reaches 15%or the extrusion force reaches 100KN or 1000 times;the external resistance is 80mΩand the short-circuit time reaches 24 hours;and the maximum temperature does not exceed 150℃.

FAQ:
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 cylindrical sodium-ion battery for 3C digital products/power tools/ESS is with over 2000 times cycle life, support -40℃ low temperature discharge temperature, much safer than lithium ion material.
