power queen 12V 10A LiFePO4 Charger — 14.6V CC/CV Fast Charging, BMS‑Friendly Aluminum Case

Power Queen 12V 10A LiFePO4 Battery Charger delivers a dedicated 14.6V/10A CC/CV charging cycle engineered specifically for 12.8V LiFePO4 (LFP) batteries, providing fast, safe recharges and BMS-friendly pre-charge functionality.

Designed for users who run 12.8V LiFePO4 battery systems — from portable power stations and marine banks to RV house batteries and solar energy storage — this compact aluminum charger applies the correct two-stage constant current / constant voltage (CC/CV) profile that LFP cells require. Its 10A output fills medium-to-large LiFePO4 batteries quickly while built-in protections and a cooling fan preserve both charger and battery health.

How does this charger support LiFePO4 batteries differently than lead-acid chargers?

The Power Queen unit uses a 14.6V termination voltage and a CC/CV algorithm tailored to LiFePO4 chemistry, avoiding over-voltage and improper charge profiles common with generic chargers. A Pre-Charge feature allows the charger to wake BMS-protected packs down to 0V so charging can begin safely.

• 14.6V maximum charging voltage set for LFP cell requirements
• Two-stage CC/CV charging for stable charge termination
• Pre-Charge to activate BMS on deeply discharged batteries

How fast will a 12V LiFePO4 battery charge with this 10A charger?

Charging time depends on battery capacity and starting state of charge, but at 10A this charger significantly reduces fill time compared with low-current chargers. For example, a 50Ah 12.8V LiFePO4 battery can reach full charge in roughly five hours from a typical mid-level state of discharge.

• 10A constant current for rapid replenishment of medium-large packs
• Estimated ~5 hours to fully charge a 50Ah LiFePO4 battery from most states
• Better than slower 3A chargers which can take 15–20 hours for the same capacity

What protections and construction features keep charging safe and reliable?

The Power Queen charger includes multiple safety circuits and a durable housing to protect both the charger and the battery during use. Over-temperature, short-circuit, reverse-polarity and output over-voltage safeguards reduce the chance of damage from incorrect connections or extreme conditions.

• Over-temperature cutoff and built-in cooling fan for thermal control
• Reverse polarity and short-circuit protection to prevent mishaps
• Aluminum alloy case with oxidation treatment for durability

What accessories and battery sizes is this charger intended for?

The charger ships with heavy-duty power cord and battery charging leads suitable for routine use with 12.8V LiFePO4 banks. It works best on batteries rated about 20Ah and higher, where its 10A current is efficient and appropriate.

• Includes heavy-wall cord and battery clips for secure connections
• Optimized for LFP packs 20Ah and above, including 50Ah and larger
• Compact form factor for workshop, garage, RV or marine storage

Who is this for? The Power Queen 12V 10A LiFePO4 Battery Charger is intended for homeowners, DIYers, RV and boat owners, off-grid solar users and anyone who uses 12.8V LiFePO4 battery systems and needs a faster, chemistry-appropriate charger. If you want a purpose-built charger that wakes BMS-protected packs, charges at an efficient 10A rate, and includes multiple safeguards and a cooled aluminum housing, this model is a practical choice. It is not designed for lead-acid charging profiles; use with LFP batteries only.
