12V Sodium-Ion Battery Charger for 4S Packs, NFPP or Layered Oxide, Pre-Programmed

A charger set up for your 12V Sodium-ion pack before it ships. We program the charge voltage and current for your exact cell count, bench-test it, and put the settings card in the box. You connect it to your pack and charge.

Built for: 4S sodium-ion packs (12V-class), including cold-climate builds.

Why this charger fits your pack

• 4S Sodium: charges to about 15.2–16.0 V
• Charge profile: CC/CV, Set from your cell's datasheet (typically ~3.8V max for NFPP and ~3.9V max for Layered Oxide).
• Auto-detect turned off. The charger only ever runs the curve we set for your pack, so it can't guess wrong.
• Safety certified (UL/IEC 62368-1), universal AC input 90–264 VAC with PFC, fan cooled.
• Protections: over-voltage, over-current, short-circuit, over-temperature, reverse polarity (fused).

Pick your cathode. NFPP and layered-oxide sodium cells use different charge voltages, so we program each one differently. Your cell datasheet names the cathode; if you bought cells from us, the listing says which. Not sure? Send us the cell model and we'll tell you.

Pick a power

Approximate time from empty to full, with the current capped at 0.5C. We set the charge current to 0.5C or less for your pack unless you ask otherwise, so a big charger is safe on a small pack.

How it ships

• Made to order: ships in 3–5 business days, programmed and tested on our bench.
• Want different settings (90% charge for longer life, lower current, a float stage)? Add a note at checkout.
• DC output is screw terminals. Bring your own cable and connector sized for the current.
• Use with a pack that has a BMS. Indoor, dry, ventilated location.
