Hello Operators.
You all know I’ve been testing Power Queen LiFePO4 batteries since August of 2023. So far, so good! With all the projects completed with Power Queen batteries on the channel, I thought it would be a good idea to announce their Prime Day sale. Not only can you get larger discounts during the sale, your purchase supports the channel and blog indirectly, and without cost to you. If you’ve been on the fence about trying LiFePO4, this might be a great time.

LiFePO4 is an excellent energy storage technology. It outperforms a comparably sized lead-acid battery in lifespam, charging and depth of discharge. LiFePO4 isn’t as volatile as LiPo or Lithium-ion with it being increadibly difficult to get them into a state of thermal runaway. This makes them safe for portable ham radio and emergency communications, overlanding, camper vans, boating, or as the energy storage solution for your solar-powered home.

Power Queen LiFePO4 batteries

Power Queen has supported many of the projects found on the channel and blog. I have used these batteries exclusively since August 2023. I have had some logistical issues with Power Queen in Europe, but they always get things sorted out. Regarding the battery hardware, the packs have performed reliably, and even better than expected. Theyve been reliable, and consistent, making the entire experience a positive one. For the camper caravan project, Power Queen provided a 280ah 3584wh LiFePO4 battery. The battery has a 200 amp load capability, 4000 charge cycles at 100% DOD.

Manufacturers like Power Queen are important as they bridge the cost gap between traditional lead-acid batteries, and the better performing, better value LiFePO4.

Don’t forget Power Queens Prime Day sale for USA and Europe.

Benefits of LiFePO4 over lead-acid

The main benefits of LiFePO4 (Lithium Iron Phosphate) batteries over lead-acid batteries include:

  1. Longer Lifespan: LiFePO4 batteries typically last 5-10 years or more, with thousands of charge cycles, compared to lead-acid batteries, which last 2-5 years with fewer charge cycles. For LiFePO4, the goal post is generally 4000 cycles at 100% DOD.
  2. Higher Efficiency: LiFePO4 batteries have a higher charge and discharge efficiency, often around 95-98%, whereas lead-acid batteries have an efficiency of about 70-85%.
  3. Weight and Size: LiFePO4 batteries are much lighter and more compact than lead-acid batteries, which makes them easier to handle and install.
  4. Greater depth of Discharge: LiFePO4 batteries can be discharged up to 80-90% of their capacity without damage to the battery. In contrast, lead-acid batteries should not be discharged beyond 50% to avoid damage which materializes itself as a reduction in cyclic life..
  5. Maintenance: LiFePO4 batteries are completely maintenance-free!
  6. Environmental Impact: LiFePO4 batteries are more environmentally friendly as they do not contain toxic heavy metals like lead, and they are easier to recycle.
  7. Discharging in Extreme Conditions: Although LiFePO4 batteries perform extraordinarily well in extreme cold and heat, they cannot be charged below freezing. In contrast, lead-acid batteries are more susceptible to performance degradation in both hot or cold climates.
  8. Safety: LiFePO4 batteries are generally safer, with a lower risk of overheating and fire compared to some other lithium-ion based batteries.

Overall, LiFePO4 batteries offer significant advantages in terms of longevity, efficiency, size, weight, and environmental impact, making them a great choice for many energy storage applications.

That’s it for now.
