12V Li-ion NMC / NCA Battery Charger for 3S / 4S Packs, 12.6V / 16.8V, Pre-Programmed

A charger set up for your 12V Li-ion NMC / NCA 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: 12V-class packs built from NMC/NCA cells or modules.

Why this charger fits your pack

• 3S NMC: charges to 12.6 V
• 4S NMC: charges to 16.8 V
• Charge profile: CC/CV, 4.20 V/cell, 2-stage (no float). Ask for 4.10 V/cell (about 90% charge) for longer cycle life.
• 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 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.
