Product information
Before you order
This is a bare sodium-ion cell, not a finished battery. Current checkout is limited to the remaining physical individual cells. The next 20Ah supplier/model is not yet frozen, so Saltra is collecting free restock demand without taking deposits or promising a delivery date.
Bare cells are not a finished battery. Confirm the exact BMS voltage window, charger limits, terminal hardware, system current, and shipping path before purchase.

Confirm the balancing approach
A balancer may improve cell balance but does not replace the BMS. Compatibility must be proven for the exact cell voltage range.

required
Add busbars or cell interconnects
Terminal geometry, spacing, current and mechanical loading determine the correct interconnect.

required
Add fuse and service disconnect
Pack-level overcurrent protection and a safe isolation method are required parts of the system design.

FAQ
Before you buy
How many cells are currently available?
Three individual cells remain. Four-cell and sixteen-cell sets are sold out.
Is this a finished 12V battery?
No. This offer is for individual bare cells and fewer than four remain. Protection, charging, interconnects, fuse, wiring, insulation, restraint and enclosure are not included unless explicitly stated.
Are a BMS, balancer, busbars, or charger included?
No, unless the selected offer explicitly lists them. Saltra will only recommend a specific accessory after exact compatibility is approved.
Will the cells ship to my location?
Shipping eligibility is confirmed for the exact quantity, destination, carrier service and available transport documentation before fulfillment.
