I ordered a Power Queen MPPT Charge Controller, (3) Power Queen Batteries, and a Power Queen Inverter through Ebay. In order to safeguard safety in putting my Solar Generator together, I communicated with the Power Queen company. I had at least a dozen questions along the way and Jennifer and the Power Queen Technical Team guided me all the way. I will recommend Power Queen products and service to friends and acquaintances in the future. Thank you. Respectfully Submitted: Lawrence L. Harlowe

I got a reply to a question o had before I ordered them and it was the prompt. I appreciate that from whomever I deal with and hope that continues thru my use of these batteries. Whenever I receive any kind of service I use I will recommend the dealer to others. You have business practices that all buyers or people who inquire appreciate very much. I was told about Power Queen from a friend who has friends that recommended you, so your kindness and prompt replies do make a difference. I wish your company the best of luck and thank you and your staff from me. Have a good day

About Power Queen
Power Queen manufactures LiFePO4 battery systems and related power equipment for off-grid, marine, RV, and renewable energy applications. The brand focuses on accessible lithium battery technology, offering drop-in replacements for traditional lead-acid batteries in 12V, 24V, and 48V configurations. Their catalog includes deep-cycle batteries, trolling motor batteries, solar charging systems, and DC chargers designed to work together as complete power solutions.
The company positions itself as a beginner-friendly entry point into lithium battery systems, with products that don't require complex installation or specialized knowledge. Power Queen batteries are built with built-in battery management systems (BMS) that handle cell balancing, temperature monitoring, and overcharge protection automatically. This makes them suitable for first-time lithium battery users who want the performance benefits (lighter weight, longer lifespan, faster charging) without the learning curve of managing individual cells.
Power Queen serves boaters upgrading trolling motor power, RV owners seeking longer battery life between charges, off-grid solar enthusiasts, and homeowners switching to electric lawn equipment. The Power Queen Reviews on Trustpilot provide customer feedback on product performance and support experiences.
Buying guide
3 parts, about 3 min readBefore you buy
If you're new to lithium batteries, match the amp-hour (Ah) capacity to your actual power needs rather than simply replacing your old lead-acid battery with the same Ah rating. Because LiFePO4 batteries can be discharged to 100% depth without damage (versus 50% for lead-acid), a 100Ah Power Queen lithium battery provides usable energy equivalent to a 200Ah lead-acid battery. Oversizing wastes money, while undersizing means you'll hit low-voltage cutoff sooner than expected during use.
Check your existing charger compatibility before ordering. Many older lead-acid chargers will technically charge a Power Queen battery, but they won't optimize lifespan or charge speed because they use the wrong voltage profile. Power Queen's DC charger products are programmed for LiFePO4 chemistry and will fully charge the battery faster and safer. For marine applications, verify your trolling motor's voltage requirements, some motors labeled "24V" actually need two 12V batteries in series rather than a single 24V battery, and the wiring differs. Power Queen customer service can clarify compatibility questions before you order, which saves return shipping costs on heavy battery orders.
What to buy
The Power Queen LiFePO4 battery is the brand's core product, available in multiple voltages and capacities. The 12V LiFePO4 battery comes in sizes ranging from 50Ah to 300Ah, making it suitable for everything from small fish finders to full RV house battery banks. These batteries use lithium iron phosphate chemistry, which is safer and more stable than other lithium types and tolerates thousands of charge cycles. The built-in BMS protects against common battery failures, so you don't need external monitoring equipment.

For marine applications, the trolling motor batteries are optimized for high-draw, sustained loads. A 12 volt lithium battery from Power Queen typically weighs 60-70% less than an equivalent lead-acid battery, which matters when you're carrying it to a boat or mounting it in a kayak. The 24V lithium battery options are popular for larger trolling motors (80-pound thrust and up) and can be purchased as a single integrated unit or assembled from two 12V batteries in series.
The 48V battery systems are designed for solar storage and electric vehicle applications, including e-bikes and electric lawn mowers. Power Queen's electric lawn mower line is aimed at homeowners who want cordless convenience without gas engine maintenance. The DC charger products include both AC-to-DC chargers for home use and DC-to-DC chargers for vehicle-based charging, with models specifically designed for LiFePO4 charging profiles (different from lead-acid chargers). If you're building a complete off-grid system, pairing Power Queen batteries with compatible Smart Plugs & Outlets can help you monitor and control power consumption.
How to save
The GRACE code works across all product categories without minimum purchase requirements, which is straightforward for first-time buyers. Since Power Queen sells relatively expensive items (batteries typically range from $150 to over $1,000), even a 6% discount represents significant dollar savings. The code applies to bundle purchases, so if you're building a battery bank with multiple units, you'll save on the entire order.

Power Queen occasionally runs limited-time promotions on specific battery sizes or product lines, but the brand does not heavily discount its core LiFePO4 battery products outside of major shopping holidays. Watching for these events can yield better savings than the standard code, though availability can be limited. Creating an account before checkout sometimes reveals member-only pricing or early access to sales.
Some customers save by purchasing directly from the Official LifePo4 battery website in their region, as international versions sometimes have different shipping policies. The Power Queen promo code applies at checkout regardless of cart size, making it useful even for smaller accessory purchases like chargers or cables.
Questions
Does the Power Queen discount code work on all battery sizes?
Yes, the GRACE code applies to all LiFePO4 battery capacities and voltages, including 12V, 24V, and 48V systems, as well as trolling motor batteries, chargers, and electric lawn mowers. There are no exclusions or minimum purchase requirements.
How do I use the code at checkout?
Enter GRACE in the discount code field on the checkout page at ipowerqueen.com, then click apply. The 6% discount will appear in your order summary before you complete payment.
Is Power Queen coupon code the same as the promo code or voucher code?
Yes, the terms coupon code, promo code, and voucher code all refer to the same thing: GRACE is the Power Queen code that saves 6% on all orders. Use whichever term you prefer, they all mean the same discount.
Where are Power Queen batteries made?
Power Queen batteries are manufactured in China with LiFePO4 cells and battery management systems designed for international markets. The brand focuses on quality control and safety certifications for marine, RV, and solar applications.
Can I return a Power Queen battery if it doesn't fit my application?
Power Queen offers a return policy, but batteries are heavy and return shipping costs can be substantial. Contact Power Queen customer service before ordering to confirm compatibility with your specific trolling motor, RV, or solar system to avoid returns.
Do Power Queen lithium batteries need a special charger?
LiFePO4 batteries require a charger with a lithium-specific charging profile for optimal performance and lifespan. Many lead-acid chargers will charge a Power Queen battery but won't reach full capacity or may reduce longevity. Power Queen's DC charger products are pre-programmed for their batteries.
