12V LiFePO4 Battery Charger for 4S LFP Packs, 14.4V 25A, Pre-Programmed

A charger set up for your 12V LiFePO4 (LFP) 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: RV, van, boat and small solar 12V banks.

Why this charger fits your pack

• 4S LFP: charges to 14.4 V
• Charge profile: CC/CV, 3.60 V/cell, 2-stage (no float). Ask for 3.45–3.50 V/cell if you want a gentler charge for a pack that sits full.
• 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.
