12V 10A Smart LiFePO4 Battery Charger 14.6V 4S AC110-240V

12V 10A Smart LiFePO4 Battery Charger — 14.6V 4S, AC 110–240V Universal Input

Keep your lithium iron phosphate battery packs in peak condition with this intelligent 12V 10A LiFePO4 charger. Designed specifically for 12.8V (4S) LiFePO4 battery packs, it delivers a precise 14.6V charge voltage and up to 10A of charging current — making it one of the most capable smart chargers in its class. Whether you're maintaining a solar storage system, an RV auxiliary battery, or a high-capacity eBike pack, this charger handles it with built-in intelligence and comprehensive safety features.

Made in Mainland China.

Key Features

• Universal AC Input: Works on AC 110V–240V, 50/60Hz — compatible with outlets across most of the world (EU plug included; see note below for US plug users).
• Smart Multi-Stage Charging: Intelligent charge logic includes standard 10A bulk charging, a repair/reconditioning mode (600mA–800mA), and gentle trickle maintenance (30mA–170mA) to maximize battery longevity.
• Precise Output Voltage: Fixed 14.6V output perfectly matched to 4S (12.8V nominal) LiFePO4 chemistry — no risk of overcharging your pack.
• Multiple Output Connectors: Ships with your choice of Crocodile Clips, DC 5.5×2.5mm barrel, XT60, XT90, or Anderson connector — one charger works across many battery setups.
• 5-Layer Protection System: Short circuit, over-current, overvoltage, reverse polarity, and automatic thermal protection (cuts off above 85°C, resumes below 75°C) for worry-free charging.

Frequently Asked Questions

Q: Is this LiFePO4 charger compatible with standard lithium-ion (Li-ion) batteries?

A: No. This charger is designed exclusively for lithium iron phosphate (LiFePO4) batteries with a 12.8V nominal voltage (4S configuration) and a 14.6V charge cutoff. Using it with standard Li-ion batteries, which require a different charge voltage, could damage the battery or create a safety hazard.

Q: What output connector options are available with this 12V LiFePO4 charger?

A: When ordering, you can choose from five output connector types: Crocodile Clips (alligator clips), DC 5.5×2.5mm barrel jack, XT60, XT90, or Anderson connector — making this charger compatible with a wide range of battery packs and enclosures.

Q: Can I use this charger in the United States with a standard 110V outlet?

A: The charger's input supports AC 110–240V, so it is electrically compatible with US 110V outlets. However, this product ships with a EU plug. US customers will need to use an appropriate plug adapter. Please verify compatibility before purchasing.

Q: How long does it take to fully charge a 12V LiFePO4 battery pack?

A: Charge time depends on the battery's capacity (Ah). As a general guide, divide the battery capacity by the charging current (10A). For example, a 100Ah LiFePO4 pack would take approximately 10–11 hours for a full charge cycle (factoring in the multi-stage smart charging process).
