FAQ

Are Power Queen LiFePO4 Lithium batteries safe?

Yes, LiFePO4 (Lithium Iron Phosphate) is one of the safest and most stable types of lithium batteries available on the market. Each Power Queen LiFePO4 battery features an internal Battery Management System (BMS) that provides comprehensive protection against various risks. These include under-voltage during discharge, over-voltage during charging, over-current during discharge, over-temperature during both charging and discharging, and short-circuit events, ensuring the battery cells remain undamaged. Moreover, Power Queen LiFePO4 batteries have been rigorously tested and found to be free from fire hazards and electric shock risks, even in challenging environments.

Can I use Power Queen LiFePO4 Lithium batteries as starting batteries?

No. Power Queen LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

For further details, please consult the "Deep Cycle VS Starting Battery" article.

Can I charge Power Queen LiFePO4 lithium batteries in cold weather (under freezing temperatures)?

The Power Queen 12V 50Ah Deep Cycle Lithium Batteries can be safely charged within a temperature range of 32℉ to 122℉ (0℃ to 50℃). However, charging below freezing temperatures can potentially damage the battery cells.

How do I store Power Queen LiFePO4 lithium batteries?

For optimal storage of Power Queen LiFePO4 batteries, it is recommended to keep them at a 50% state of charge (SOC). If the batteries will be stored for an extended period, it is advisable to cycle them at least once every six months. Recommended storage environment: 10℃~35℃ (50℉~95℉), 45%RH~75%RH.

For more detailed, you can read the article: Storing LiFePO4 Batteries: A Guide to Proper Storage.

What is the maximum discharge capacity of a Power Queen 12V 50Ah Deep Cycle Lithium Battery?

The Power Queen 12V 50Ah Deep Cycle Lithium Battery has a maximum continuous discharge of 50Ah and a peak discharge of 100Ah for 5 seconds.

What is the lifespan of the Power Queen 12V 50Ah Deep Cycle Lithium Battery?

A Power Queen LiFePO4 lithium battery can be used for 4000-15000 life cycles, which can be 10 years or more depending on usage. Lead acid and AGM batteries have about 300-500 life cycles before their capacity is significantly reduced. Despite the higher initial cost, upgrading to a Power Queen LiFePO4 battery will save you a lot of money in the long run.

How do I know what size the Power Queen LiFePO4 lithium battery I need?

The Power Queen LiFePO4 lithium battery has approximately twice the useful capacity of lead acid and AGM batteries. So, if you want longer useful battery time (Amps), you should upgrade to a battery of the same (or higher) Amps. For example, if you replace a 100amp battery with a Power Queen 12V 100Ah LiFePO4 Lithium Battery, you will obtain around twice as many useful amps while weighing half as much. If your goal is to have a battery that is smaller, lighter, and less expensive. Then, replace the 100amp battery with a Power Queen 12V 50Ah LiFePO4 Lithium Battery. You will receive roughly the same number of useful amps (time), but it will cost less and it's about 1/6 the weight.

Can Power Queen LiFePO₄ batteries be used to charge a portable power station?

No, we do not recommend using Power Queen batteries to charge portable power stations such as EcoFlow or Bluetti. This may lead to over-discharge, triggering the battery’s protection mode and causing it to remain in a low-voltage state that cannot be reactivated.

Love the charger and battery work grate with my ham radio setup

R
Robert S.

Last week I used my 50Ah Power Queen as the only source of battery for one of my ham radios. This radio and I were on the air for about an hour each morning as I transmitted at the 25 watt level. We lasted 5 days before I needed to recharge it. The radio I was using has a volt meter that displays voltage when the radio is turned on. The radio does not transmitt if the voltage is below 13.2 volts. I am very very please with my 12 pound load when I go out on specail Amateur radio call outs. Bob Smith WB6ODR

I’ve had 2 of these in my homemade remote control mower for over a year now and they work great. I had 2 lead acid batteries in it before and didn’t get a 3rd of the mowing time I get with these. I’m really glad a friend told me about them. These things were well packaged. This is a great company and just because their prices are lower doesn’t mean their quality is. They are well made.

R
Richard L.

I really love these batteries. I was using two 35ah batteries on my remote control mower I built for mowing a steep hillside. I could only mow half and batteries would be very low. I installed two 50ah Power Queens and mowed it all and only used 20% of the power. What a difference. These are great batteries and I highly recommend them. The big 24 volt charger also works well.

These batteries are awesome. They fit perfectly in my toolbox that I use for my trolling motor. The weight of each battery is as advertised. The only minor gripe is the sticker is not straight on one battery. Shipping was fast and packaged well. They included extra battery terminal bolts which was nice. The manual is well written. Prior to ordering, I emailed PQ and response time was within one day. Would buy again.

I have multiple PQ batteries ranging in size from 50AH to 410AH. They are 100% reliable, always exceed their published capacity, and are now my go-to source for high power density.

R
Raymond Z.

I am using this as a battery for my trolling motor for my kayak. I like the size and the weight. I could keep this in the front hatch of my kayak if I wanted but I did buy a battery box to put this in and will mount it behind my seat. I haven't had a chance to try it out yet and see how long it will last as I am still waiting on a few items to finish my build. I'm sure the 50ah size will be plenty for a day of fishing and if not, I'll just buy another PQ battery in 100ah. These things are a good price.

I had a great experience with powerqueen's customer service. Due to problems created by FedEx, my initial shipment was mishandled and completely lost in transit. Powerqueen's customer service immediately remedied the service and put the order through a dependable courier (ups) and I received my package right on time as they said.
